Overview
TheKEMETT491,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.TheT491isclassiedasmoisturesensitivity
level(MSL)1underJSTD020,with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
& 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 details.
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.

(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 details.
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the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.

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 density 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.
2 Land pattern geometry is too small for silkscreen outline.

Tantalum Surface Mount Capacitors – Standard Tantalum
T491 Industrial Grade MnO2
Soldering Process
The KEMET 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
di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40°C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 suffi 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 (see Figure 2).
(d) lateral movement of the component is restricted to 0.5 mm maximum for 8 mm and 12 mm wide tape (see Figure 3).
(e) see Addendum in EIA Standard 481–D for standards relating to more precise taping requirements.
