FerriShield Ferrites are recognized for their ease of installation and reliable performance over time. FerriShield Ferrites are designed to fit tight against the cable or wiring bundle that requires shielding. Ideally, you should select a ferrite with an inside diameter that is slightly less (+/- .04") than the outside diameter of your cable. For quick reference, all part numbers in this catalog have an accompanying technical drawing and specifications chart that illustrates dimensions and impedance for the selected ferrite. For a more detailed technical explanation see page 33. Helpful Tips and Insider Hints * Ferrite performance typically increases as ferrite volume increases. The larger the ferrite mass, the better the RF attenuation. * Smaller cables can be looped through larger ferrites to increase performance. Impedance increase by the square of the number of loops. For example, by looping a cable through a ferrite 2 times (22), impedance increases by a factor of 4. For a detailed explanation see page 6- Electromagnetic Characteristics * Ferrite installation guidelines and recommendations are shown on page 35 * Attenuation properties by part number can be referenced on page 32 * Maximum recommend cable size by part number can be found on page 33 5 a powerful insertion loss device Product Profile Electromagnetic Characteristics Ferrite shielding materials are widely accepted as providing the simplest, most convenient and most cost-effective solution for radio frequency interference problems in cables and connectors. Further, they accomplish both RF attenuation and suppression of unwanted high frequency oscillations with no loss in dc or low frequency signal strength. Stated most simply, the operative characteristic which makes ferrites effective in RFI/EMI suppression is their variable sensitivity to frequency. With a ferrite installed as a suppressor, lower frequencies will pass with no significant loss. But above the frequency where (tan d/) climbs sharply (see figure 1), the signal couples with the ferrite to create an impedance which is quite high compared with the rest of the circuit. The offending RFI is thus immediately and consistently blocked out by way of impedance damping of the unwanted high frequency signals. It is this greater resistive impedance which allows the basically passive, apparently simple material to suppress multiple signals in a variety of application situations. The basic composition of ferrite materials is a combination of ferrous oxide and one or more other powdered metals most often manganese, zinc, cobalt or nickel. An extensive selection of shapes and sizes is already available, and custom geometries may be manufactured for special situations. There are infinite varieties of formulas and performance levels possible. Each discrete ferrite formulation results in a stoichiometric ratio which is its performance characteristic signature regarding electrical, magnetic and mechanical relationships. The most common expression of ferrites' performance capabilities is in terms of their permeability (). This property expresses the ratio of the magnitude of magnetic induction to magnetizing force. The materials are normally categorized according to initial permeability (i). 20 Permeability ( i) #20 Ferrite (Microwave formula) TYPICAL PERFORMANCE 1000 B 100 A C 125 Permeability ( i) #25 Ferrite (Specific, high-frequency formula) 850 Permeability ( i) #28 Ferrite (Popular, universal formula) fig. 3 Two turn loop through ferrite increases effective magnetic path. Impedance increases by the square of the number of turns (N2). 2700 Permeability ( i) #33 Ferrite (Specific, low-frequency formula) 10 1 fig. 2 Impedance comparison vs. cubic volume. 1M 10M 100M FREQUENCY (Hz) 1G fig. 1 Typical attenuation profiles FerriShield has developed four principal formulations which together serve the common spectrum of today's RFI needs. For frequencies from 10 MHz to 1 GHz, #28 formulation is recommended, especially when higher frequency harmonics are a consideration. For frequencies typified by microprocessor speeds in excess of 100MHz and harmonics peak interference at nominally 700MHz, #25 formulation is designed to cover this range with even some effect beyond that. For frequencies from 1 MHz to 30 MHz, #33 material offers a concentration of impedance in that range with a decreasing effect above 30 MHz. For microwave frequencies relating to BluetoothTM 2.45GHz operations, the #20 material is available. See figure 1 above. fig. 4 Increased impedance; multiple turns (N2) vs. one turn through ferrite; i.e., 2 turns (22) = 4 times impedance 6 a powerful insertion loss device Organizing the Engineering Model Even though the same unit of ferrite is used, the attenuation provided by a ferrite suppressor can differ somewhat as the original circuit impedance varies. The ferrite is more effective when the circuit impedance is low. For example, by using the same 250 ohm ferrite in a 75 ohm circuit, the result will be: To understand the various practical modeling techniques employed with ferrite, it is best to prepare a properly engineered calculation of expected results. An empirical trial and error method may leave the circuit close to borderline performance without adequate safety margins. As indicated previously, a wide range of formulations is possible. The major application factors to be used when defining a specific ferrite solution for a particular interference problem include the following: With a high circuit impedance, it may be possible to increase the number of turns or passes through the ferrite (figures 3 and 4), or to use a larger amount of ferrite (cubic volume) in the circuit in order to achieve the same level of insertion loss (fig. 2). By increasing the number of turns (passes) through the ferrite opening, the "effective magnetic path" is increased _ impedance then increases by the square of the number of turns (N2) ; i.e., two turns (22) = 4 times the impedance. When additional ferrite volume is added, impedance increases on almost a direct percentage basis; i.e., a 100 percent increase in volume will provide about 100 percent increase in impedance (figure 2) in most situations according to certain prescribed dimensional ratios. - Frequency where maximum attenuation is required. - Amount of attenuation needed. - Ferrite permeability formulation characteristics as they relate to the frequency range in question (i.e., initial permeability) - Ferrite formulation consistency (i.e., expected range of variation in attenuation performance) - Installation environment and mechanical attachment requirements. An alternative modeling procedure may also be structured in reverse by solving for a desired insertion loss goal. The result yields an impedance requirement. This can be matched to known performance profiles of existing ferrite configurations in the geometric style best suited for mechanical and packaging requirements. The frequency range requiring attenuation must be matched to the performance of a given ferrite composition (figure 1 on previous page). The optimum profile would be a ferrite in which the highest attenuation level coincides with the disruptive frequency (A). That same ferrite could be used even if the frequency falls in a lower area of its impedance curve (B) but there would be correspondingly reduced attenuation. Conversely, a different ferrite formulation could be employed in the same frequency situation with the intent of using a lower part of its performance curve (C). Space and weight considerations are not normally a concern since good quality ferrites provide high performance per a given cubic volume. As an example, a 15dB insertion loss is required for a flat ribbon cable at 100 MHz. Using the formula: Insertion Loss (dB) = 20 log10 (ZA + ZB + ZF) (ZA + ZB) Where: IL = 15 dB ZA = 25 ohms ZB = 25 ohms ZF = Unknown ferrite impedance (solve for this value) The modeling procedure to calculate impedance characteristics of the source and load coupled with the ferrite suppressor is developed as follows: Insertion Loss (dB) = 20 Log10 (75 + 250)/75 = 12.7 dB ( 15dB = 20 Log10 50 + ZF 25 + 25 0.75 = Log10 50 + ZF 50 5.625 = 50 + ZF 50 ZF = 231.25 ohms ( 20 log10 (ZA + ZB + ZF) (ZA + ZB) Where: Insertion Loss = A measure of the effectiveness of a filter, expressed in decibels, is described as the ratio of voltages with, and without, the filter in the circuit. ZA = Source Impedance ZB = Load Impedance ZF = Ferrite Impedance ) ) Next, refer to the Attenuation Properties on page 36. The flat ribbon cable style part that closely matches is #28B2480 with a 2501/2 impedance at 100 MHz. Once the ferrite suppressor is installed in the circuit, results should be confirmed by testing. Although these ferrites are "linear," the term is relative to the common operating range of temperatures. The permeability is different at every degree of temperature. The published initial permeability (i) nomenclature applies to standard temperature, 59F (15C) only. There are only minor impedance differences, however, throughout normal operational ranges and up to 180 F (82C). See Material Properties on page 33. If the circuit impedance (ZA + ZB) is 50 ohms and the ferrite impedance is 250 ohms, then the insertion loss will be: 20 Log10 (50+250)/50 = 15.56 dB 7 ferrites for interference control FerriShield Advantages Controlling RFI/EMI Any device used to block an RFI signal between its source and a receiver is an electromagnetic interference (EMI) shield. 1,000,000:1 99.999 100,000:1 99.99 10,000:1 99.9 1,000:1 99.0 100:1 90.0 10:1 ATTENUATION RATIO PERCENT ATTENUATION 99.9999 I/O cable with RFI suppressor. 0 20 40 60 80 100 120 SHIELDING EFFECTIVENESS (dB) The concept of bisected ferrites has been developed to address a number of industry needs in the area of Electromagnetic Compatibility, EMC. * engineering adaptability * risk-free engineering: - tight tolerance performance - easy to upgrade attenuation by changing size or number of turns. * easy retrofitting * convenient installation * integral mounting features * cost-effectiveness * extended resistance to core saturation under Direct Current loads. * consistent performance The measure of this ability to attenuate RFI is Shielding Effectiveness, SE, which is expressed in decibels, dB, the ratio of field strength on one side of the shield to the other side. The figure above shows the relationship between shielding effectiveness (in dB), the amount of attenuation, and attenuation percentage. UL recognized plastic case Bisected ferrite RFI absorber Cable gripping entry/exit port Typical FerriShield RFI suppressor. Gap effect of ferrite subjected to direct current. Design Support The technical air gap in bisected ferrites actually extends current carrying capability with only an imperceptible reduction in impedance versus solid ferrites of the same size. The gap is magnetically insignificant while it is electrically significant as a discontinuation, thereby accommodating more current. Engineering assistance is always available. We will be pleased to help with applications, cross-referencing or complete insertion loss calculations when a custom suppressor is required. For attenuation properties by frequency, see page 32 8 ferrites for interference control Installation is simple Just snap over circuit wiring to be controlled - even after wiring has been terminated Radio interference sources usually radiate their RFI power at frequencies above 30 MHz by way of the main cabling, which acts as an antenna. Anywhere There is an Antenna-Like Structure Electronic cabling and wires, by virtue of their length-to-width ratios, are perfect natural antennas. In the presence of high speed microprocessor signals, cables will conduct, radiate and/or receive unwanted high frequency interfering signals. Control of radio frequency interference can be assured by proper placement of an insertion loss device, such as a ferrite suppressor.

Power distribution characteristics pass unimpeded Advantages Compared to other alternatives, ferrites' high resistivity per cubic volume stands out as the most important advantage. Prior to the development of bisected ferrites, suppression engineering was restricted to the costly addition of filters, cable shielding, and less versatile solid core (not bisected) ferrites. While these methods offer a degree of suppression, they are often awkward to install and, in many cases, are not completely effective. Bisected ferrites have a concentrated, homogeneous magnetic structure with high permeability. They are consistently stable versus time and temperature, and provide RF suppression without high eddy current losses. 9 wideband ferrites- up to 1GHz applications 28 material cable snap C Ferrite assembly in fully enclosed nylon case; functional with wires and cables up to a 2.0" (50,8mm) diameter.

Any of the round or flat cable clamps shown elsewhere in this catalog make a perfectly good solution for many bus bar geometries and their mounting requirements. A properly placed suppressor will attenuate unwanted high frequency signals, thus negating the conductor and/or antenna-like radiating effects at specific frequencies while not disturbing the power distribution characteristics. For attenuation properties by frequency, see page 32 21 D .325" (8,3mm) G IMPEDANCE IN OHMS .200 5,1 180 @ 100MHz .200 5,1 160 @ 100MHz B A For situations where extremely high amounts of attenuation are needed. Can be strapped longitudinally onto bus bars with common cable tie-wraps; or, potting compounds can be used. Sandwiching the bus bar between two shielding bars will dramatically increase impedance up to three times the effect of a single bar depending on frequencies involved.

From management of warehouse inventory to identification of patients in a medical setting, proper deployment and unimpeded communication between RFID readers and tags is paramount to successful operation. One of the major considerations when implementing an RFID system is the effect of unwanted RF interference between Readers and Tags. Most workplaces have hundreds if not thousands of electronic devices that create unwanted interference, including computers, Bluetooth networks, wireless networks, motors, conveyors and robots. Actually, any device with a microchip and power cord or cable will emit RF energy which can interfere with the ability of the reader to receive a clean signal. Leader Tech offers a simple "first-step" approach to reducing unwanted RF interference. We recommend the following: Identify Sources of RFID Interferences The FerriShield CTK031 hand-held probe (see below) is one of the easiest ways to identify unwanted electro-magnetic interference. All you need to do is pass the probe over suspect sources. If the device detects RF emissions it alerts with an audible tone that intensifies as interference increases. Attach a Frequency-Specific RFID Ferrite to the Suspect Device Samplings of our most popular RFID ferrites are shown on the following page. In addition, a free 32-piece engineering kit is provided with the purchase of any CTK031 Probe. Check If Interference Has Been Eliminated After you have attached the cable-mounted ferrite, simply use the hand-held RF probe to confirm that the ferrite has eliminated the unwanted interference. CTK031 - SCAN EM-C PROBE SET WITH DEMO FIXTURE Contains both CTM030 electric and CTM032 magnetic near-field probes along with a step-by-step guide, an EMC Demo Fixture, and cables with adapters for spectrum analyzer, oscilloscope or multimeter.

ScanEM probes are diagnostic instruments for detecting, locating and measuring electromagnetic emissions. They are professional tools that don't require you to be an EMC expert to completely address emission compliance. They can reliably predict electromagnetic behavior of your products and locate emission sources in a matter of seconds. They detect the presence of an electromagnetic field and provide audio and visual indication of its relative strength either working by themselves, or as broadband active probes with any spectrum analyzer, oscilloscope or multimeter. * Pinpoint exact sources of EMI * Detect electric and magnetic fields separately * Self-contained: palm-sized, no cords, no power supply or amplifier * Audio output: tone changes indicate field strength * LED color bar verifies relative field strength * Squelch feature nullifies ambient to locate problem areas * Output to spectrum analyzer or oscilloscope if desired * DC output to multimeter for DC voltage as a function of field strength * No disturbance of circuit under test - does not touch the circuit WHY NEAR-FIELD TESTING? The standard radiated EMC test is done in the far field at 10'-0" (3M) from the product. This shows if there is a failure, but does not pinpoint the source of the problem. A near-field probe is a close-up inspection which permits quick product scanning for problem areas. * PC board traces * Trouble shooting * Production quality control *Service and repair * Prequalification * Cables, connectors - to a single circuit or pin * Production quality control * Service and repair * Non-contact diagnostics - no circuit loading A day spent at the beginning of a project preventing EMC problems saves days, even weeks, fixing these problems at the end.

For attenuation properties by frequency, see page 32 34 installation Installation Guidelines FerriShield(R) suppressors offer the finest performance alternatives by way of universal packaging, specific-purpose and general-purpose formulations. There are a few simple guidelines to assure expected results. 1. Cable Size Refer to the chart on the page 33 for maximum recommended cable (or cable bundle) diameter. More than one cable may be inserted through the core opening since each circuit reacts with the ferrite material independently. Consider the double loop knot shown in Attachment section below for snug attachment while greatly increasing the attenuation effect due to the increased magnetic path length. See also page 6, figures 3 and 4 for related technical information. 2. Closure A tight fit between the cable outside dimensions; i.e. O.D., and the ferrite inside dimensions, i.e. I.D., will create the most effective magnetic path and a correspondingly higher attenuation ratio. Conversely, a loose fit is acceptable for many reasons, principally if a larger ferrite is desired, or a purpose-fit slack cable for tension control, flexing, etc. 3. Position RF SOURCE The suppressor should normally be located close to the cable termination where it exits the electronic enclosure. Where a cable connects two enclosures containing RF sources, a suppressor on each end may be required. For circuits within an enclosure, a position close to the RF source is best; however, other locations along the circuit may work just as well. This provides the opportunity to allow the suppressor, when affixed to the enclosure, to function also as a cable routing guide. See "Attachment" below for alternatives. 4. Attachment Tight grip on cable Double loop knot Hardware: screw, rivet Pressure sensitive adhesive Cable tie wrap Side-by-side double loop for flat cables 35 RF SOURCE AUXILIARY EQUIPMENT OR POWER SOURCE RF SOURCE RF SOURCE OR RF SOURCE ELECTRONIC ENCLOSURE Consider the various attachment alternatives shown below.
