To avoid such problems, observe the following precautions when using the tantalum capacitors. OPERATING VOLTAGE The voltage derating factor should be as great as possible. Under normal conditions, the operating voltage should be reduced to 50% or less of the rating. It is recommended that the operating voltage be 30% or less of the rating, particularly when the tantalum capacitors are used in a lowimpedance circuit (see Figs. 1, 2, and 3). For circuits in which a switching, charging, discharging, or other momentary current flows, it is recommended that the operating voltage be 30% or less of the rating, with a resistor connected in series to limit the current to 300 mA or less. When the tantalum capacitors are to be used at an ambient temperature of higher than 85, the recommended operating range shown in Fig. 3 should not be exceeded.

Please consult us detail in formations. Ripple Current The maximum permissible ripple current, IMAX, is calculated as follows : PMAX IMAX = ESR(f) where: IMAX : Maximum permissible capacitor ripple current (Arms). PMAX : Maximum permissible capacitor power loss (W). Varies with the ambient temperature and case size. Calculated according to Table ESR(f): Capacitor equivalent series resistance (). Since the ESR(f) value varies with the ripple frequency, however, the following correction must be made in accordance with the operating frequency (see Fig. 4). ESR(f) = K * ESR(120) K : Coefficient for the operating frequency (Fig. 4). ESR(120) = Tan * Xc = Tan 2fC where: ESR(120) : Equivalent series resistance at 120 Hz (). Xc : Capacitive reactance at 120 Hz (). C : Electrostatic capacitance at 120 Hz (F). f : Operating frequency (Hz).

The tantalum capacitors must be used in such a conditions that the sum of the Working Voltage and ripple voltage peak values does not exceed the rated voltage (Fig. 5) Ensure that an reverse voltage due to superimposed voltages is not applied to the capacitors. The maximum permissible ripple voltage varies with the rated voltage. Ensure that ripple voltage does not exceed the values shown in Figs 6 and 7. If, however, the capacitors are used at a high temperature, the maximum permissible ripple voltage must be calculated as follows: Vrms(at 55) = 0.7 x Vrms(at 25) Vrms(at 85) = 0.5 x Vrms(at 25) Vrms(at 125) = 0.3 x Vrms(at 25) 100 10 100 100 50 V 35 V 25 V 20 V 16 V 10 V 6.3/7 V 4V 2.5 V 10 100 100 1 100 10 100 50 V 35 V 25 V 20 V 16 V 10 V 6.3/7 V 4V 2.5 V 100 100 1 10 100 Frequency(Hz) Frequency(Hz) Fig.6 Maximum permissible ripple voltage Fig.7 Maximum permissible ripple voltage (P,A,B) (C,D) REVERSE VOLTAGE Solid tantalum capacitors are polarized device and may be permanently damaged or destroyed, if connected with the wrong polarity. The tantalum capacitors must not be operated and changed in reverse mode. And also the capacitors must not be used in an only AC circuit. The tantalum capacitor dielectric has a rectifying characteristics. Therefore, when a reverse voltage is applied to it, a large current flows even at a low reverse voltage.As a result,it may spontaneously generate heat and lead to shorting. Make sure that the polarity and voltage is correct when applying a multi-meter or similar testing instrument to the capacitors because a reverse voltage or overvoltage can be accidentally applied. When using the capacitors in a circuit in which a reverse voltage is applied, consult your local SAMSUNG ELECTRO-MECHANICS agent. If the application of an reverse voltage is unavoidable, it must not exceed the following values. At 20C: 10% of the rated voltage of 1 V, whichever smaller. At 85C: 5% of the rated voltage or 0.5 V, whichever smaller. RELIABILITY OF TANTALUM CAPACITORS General The failure rate of the tantalum capacitor varies with the digression ratio, ambient temperature, circuit resistance, circuit application, etc. Therefore, when proper selections are made so as to afford additional margins, higher reliability can be derived from the tantalum capacitors. Some examples of actual failure rates are presented below for your reference. Failure Rate Calculation Formula The tantalum capacitors are designed to work at their basic failure rates shown in Table 3 that prevail when the rated voltage is applied for 1000 hours at 85. Table 3 Basic failure rate TYPE Classification SCF Face-down type SCE Low ESR type SCM Ultra-Miniature type(0603) SCL Low profile type SCS Small type SCN Standard type Basic failure rate 1%/1000h Failure rate calculation formula use = 85 x KV x KR use : Estimated capacitor failure rate under the operating conditions. 85 : Basic failure rate (Table 3) KV : KR : Failure rate correction coefficient by the ambient temperature and derating factor. Failure rate correction coefficient by the circuit resistance, which is the series-connected resistance divided by the voltage applied to the capacitor. This resistance is connected in series when the power supply side is viewed from the capacitor side. K(derating factor)=operating voltage/rated voltage RELIABILITY PREDICTION Solid tantalum capacitors exhibit no degration failure mode during shelf storage and show a constantly decreasing failure rate(i.e. , absence of wearout mechanism) during life tests. this failure rate is dependent upon three important application conditions:DCvoltage, temperature, and circuit impedance. Estimates of these respective effects are provided by the reliability nomograph.(Figure 8.) The nomograph relates failure rate to voltage and temperature while the table relates failure rate to impedance. These estimates apply to steady-state DC condition, and they assume usage within all other rated conditions. Standard conditions, which produce a unity failure rate factor, are rated voltage, +85, and 0.1 ohmper-volt impedance. While voltage and temperature are straight-forward, there is sometimes difficulty in determining impedance. What is required is the circuit impedance seen by the capacitor. If several capacitors are connected in parallel, the impedance seen by each is lowered by the source of energy stored in the other capacitors. Energy is similarly stored in series inductors. Voltage "de-rating" is a common and useful approach to improved reliability. It can be persued too far, however , when it leads to installation of higher voltage capacitors of much larger size. It is possible to lose more via higher inherent failure rate than is gained by voltage derating. SAMSUNG typically recommends 50% derating, especially in low impedance circuits. Failure rate is conventionally expressed in units of percent per thousand hours. As a sample calculation, suppose a particular batch of capacitors has a failure rate of 0.5% / Khr under standard conditions. What would be the predicted failure rate at 0.7times rated voltage, 60 and 0.6/V? 120 110 101 100 80 60 50 The failure rate estimate is then : 0.5 x 7 x 10-2 x 0.4 100 90 70 The nomgraph gives a factor of 7 x 10-2 and the table gives a factor of 0.4. 102 Connect the temperature and applied voltage ratio of interest with a straight edge.

Pressure must not exceed 4.9 N with a tool end diameter of 1.5mm when applied to the capacitors using an absorber, centering tweezers, or the like. An excessively low absorber setting position would result in not only the application of undue force to the capacitors but capacitor and other component scattering,circuit board wiring breakage, and / or cracking as well, particularly when the capacitors are mounted together with other chips having a height of 1 mm or less. Flux Select a flux that contains a minimum of chlorine and amine. After flux use, the chlorine and amine in the flux remain and must therefore be removed.

Table 5 Type All case Soldering-iron tip temperature 350 MAX Time 3 sec MAX Soldering-iron power 30 W MAX Cleaning after Mounting The following solvents are usable when cleaning the capacitors after mounting. Never use a highly active solvent. - Halogen organic solvent (HCFC225, etc.) - Alcoholic solvent (IPA, ethanol, etc.) - Petroleum solvent, alkali saponifying agent, water, etc. Circuit board cleaning must be conducted at a temperature of not higher than 50C and for an immersion time of not longer than 30 minutes. When an ultrasonic cleaning method is used, cleaning must be conducted at a frequency of 48 kHz or lower, at an vibrator output of 0.02 W/cm3, at a temperature of not higher than 40C, and for a time of 5 minutes or shorter. NOTE 1: Care must be exercised in cleaning process so that the mounted capacitor will not come into contact with any cleaned object or the like or will not get rubbed by a stiff brush or the like. If such precautions are not taken particularly when the ultrasonic cleaning method is employed, terminal breakage may occur. NOTE 2: When performing ultrasonic cleaning under conditions other than stated above, conduct adequate advance checkout.
