Overview
TheKEMETT491Series,designedspecicallyfortoday’shighly
automated surface mount processes and equipment, is the
leading choice for surface mount designs. The T491 combines
KEMET’sprovensolidtantalumtechnology,acclaimedand
respected throughout the world, with the latest in materials,
processes and automation, resulting in unsurpassed total
performance and value. This product meets or exceeds the
requirementsofEIAstandard535BAAC.Thisseriesisclassied
as MSL (Moisture Sensitivity Level) 1 under J STD 020: unlimited
oorlifetimeat≤30°C/85%RH.TheT491standardterminations
are available in 100% matte tin and provide excellent wetting
characteristics and compatibility with today's surface mount solder
systems. Tin/lead (Sn/Pb) terminations are available upon request
for any part number. Gold-plated terminations are also available
for use with conductive epoxy attachment processes. Standard
packaging of these devices is tape and reel in accordance with
EIA 481. This system provides perfect compatibility with all tape-
fed placement units.

(1) To complete KEMET part number, insert M for ±20% or K for ±10%. Designates capacitance tolerance.
(2) To complete KEMET part number, insert T = 100% Matte Tin (Sn) Plated, G = Gold Plated, H = Standard Solder coated (SnPb 5% Pb minimum), N = Non-
Magnetic 100% Tin (Sn), M = Non-Magnetic (SnPb). Designates Termination Finish.
Refer to Ordering Information for additional detail.
Higher voltage ratings and tighter tolerance product including ESR may be substituted within the same size at KEMET's option. Voltage substitution will be marked
with the higher voltage rating. Substitutions can include better than series.

Ripple Current/Ripple Voltage
Permissible AC ripple voltage and current are related to equivalent
series resistance (ESR) and the power dissipation capabilities of
the device. Permissible AC ripple voltage which may be applied is
limited by two criteria:
1. The positive peak AC voltage plus the DC bias voltage, if any,
must not exceed the DC voltage rating of the capacitor.
2. The negative peak AC voltage in combination with bias
voltage,ifany,mustnotexceedtheallowablelimitsspeciedfor
reverse voltage. See the Reverse Voltage section for allowable
limits.
The maximum power dissipation by case size can be determined
using the table at right. The maximum power dissipation rating
stated in the table must be reduced with increasing environmental
operating temperatures. Refer to the table below for temperature
compensation requirements.

Using the P max of the device, the maximum allowable rms ripple
current or voltage may be determined.
I(max) = √P max/R
E(max) = Z √P max/R
I = rms ripple current (amperes)
E = rms ripple voltage (volts)

Density Level A: For low-density product applications. Recommended for wave solder applications and provides a wider process window for reow solder processes.
Density Level B: For products with a moderate level of component density. Provides a robust solder attachment condition for reow solder processes.
Density Level C: For high component desity product applications. Before adapting the minimum land pattern variations the user should perform qualication
testing based on the conditions outlined in IPC standard 7351 (IPC–7351).
¹ Height of these chips may create problems in wave soldering.

Soldering Process
KEMET’sfamiliesofsurfacemountcapacitorsarecompatible
withwave(singleordual),convection,IR,orvaporphasereow
techniques. Preheating of these components is recommended
toavoidextremethermalstress.KEMET'srecommendedprole
conditionsforconvectionandIRreowreecttheproleconditions
of the IPC/J–STD–020D standard for moisture sensitivity testing.
Thedevicescansafelywithstandamaximumofthreereow
passes at these conditions.
Please note that although the X/7343–43 case size can withstand
wavesoldering,thetallprole(4.3mmmaximum)dictatescarein
wave process development.
Handsolderingshouldbeperformedwithcareduetothedifculty
in process control. If performed, care should be taken to avoid
contact of the soldering iron to the molded case. The iron should
be used to heat the solder pad, applying solder between the pad
andthetermination,untilreowoccurs.Oncereowoccurs,the
iron should be removed immediately. “Wiping” the edges of a chip
and heating the top surface is not recommended.
Duringtypicalreowoperations,aslightdarkeningofthegold-
colored epoxy may be observed. This slight darkening is normal
and not harmful to the product. Marking permanency is not
affected by this change.

Storage
Tantalum chip capacitors should be stored in normal working environments. While the chips themselves are quite robust in other
environments, solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long term
storage. In addition, packaging materials will be degraded by high temperature– reels may soften or warp and tape peel force may
increase. KEMET recommends that maximum storage temperature not exceed 40ºC and maximum storage humidity not exceed 60%
relativehumidity.Temperatureuctuationsshouldbeminimizedtoavoidcondensationonthepartsandatmospheresshouldbefreeof
chlorine and sulphur bearing compounds. For optimized solderability chip stock should be used promptly, preferably within three years
of receipt.

1. The embossment hole location shall be measured from the sprocket hole controlling the location of the embossment. Dimensions of embossment location and
hole location shall be applied independent of each other.
2. The tape, with or without components, shall pass around R without damage (see Figure 4).
3. If S1 < 1.0 mm, there may not be enough area for cover tape to be properly applied (see EIA Standard 481–D, paragraph 4.3, section b).
4. B1 dimension is a reference dimension for tape feeder clearance only.
5. The cavity de ned by A0, B0 and K0 shall surround the component with suf cient clearance that:
(a) the component does not protrude above the top surface of the carrier tape.
(b) the component can be removed from the cavity in a vertical direction without mechanical restriction, after the top cover tape has been removed.
(c) rotation of the component is limited to 20° maximum for 8 and 12 mm tapes and 10° maximum for 16 mm tapes (see Figure 2).
(d) lateral movement of the component is restricted to 0.5 mm maximum for 8 mm and 12 mm wide tape and to 1.0 mm maximum for 16 mm tape (see Figure 3).
(e) see Addendum in EIA Standard 481–D for standards relating to more precise taping requirements.

Although KEMET designs and manufactures its products to the most stringent quality and safety standards, given the current state of the art, isolated component failures may still
occur. Accordingly, customer applications which require a high degree of reliability or safety should employ suitable designs or other safeguards (such as installation of protective
circuitry or redundancies) in order to ensure that the failure of an electrical component does not result in a risk of personal injury or property damage.
Although all productrelated warnings, cautions and notes must be observed, the customer should not assume that all safety measures are indicted or that other measures may not
be required.
