Tantalum Surface Mount Capacitors – Automotive Grade
T491 Automotive/Industrial Grade MnO2
Overview
TheꢀKEMETꢀT491,ꢀdesignedꢀspecificallyꢀforꢀtoday’sꢀhighlyꢀ
automated surface mount processes and equipment, is
the leading choice for surface mount designs. The T491
combinesꢀKEMET’sꢀprovenꢀsolidꢀtantalumꢀtechnology,ꢀ
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 physical outline and dimensions of T491
conformꢀtoꢀthisꢀglobalꢀstandard.ꢀFiveꢀlowꢀprofilesꢀcaseꢀ
sizesꢀareꢀavailableꢀꢀThisꢀseriesꢀisꢀclassifiedꢀasmoistureꢀ
sensitivity level (MSL) 1 under J STD 020, with unlimited
floorꢀlifeꢀtimeꢀatꢀ≤30°C/85%ꢀRH.ꢀTheꢀT491ꢀstandardꢀ
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. The symmetrical
terminations offer total compliancy to provide the thermal
and mechanical stress relief required for today's technology.
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 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
specifiedꢀforꢀreverseꢀvoltage.ꢀSeeꢀtheꢀReverseꢀVoltageꢀ
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 reflow
solder processes.
Density Level B: For products with a moderate level of component density. Provides a robust solder attachment condition for reflow solder processes.
Density Level C: For high component density product applications. Before adapting the minimum land pattern variations the user should perform
qualification 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.

taken to avoid contact of the soldering iron to the molded

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
storageꢀhumidityꢀnotꢀexceedꢀ60%ꢀrelativeꢀhumidity.ꢀTemperatureꢀfluctuationsꢀshouldꢀbeꢀminimizedꢀtoꢀavoidꢀcondensationꢀ
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.

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).

4. B1 dimension is a reference dimension for tape feeder clearance only.
5. The cavity defined by A0, B0 and K0 shall surround the component with sufficient 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.
