KEMET T491A336003A

Tantalum Surface Mount Capacitors – Standard Tantalum
T491 Industrial Grade MnO2 Series
Overview
The KEMET T491 Series, designed specifically 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 physical outline and dimensions of this series
conform to this global standard. Five low profile case sizes are
available in the T491 Series. The R/2012–12, S/3216–12 and
T/3528–12 case sizes have a maximum height of 1.2 mm. The
U/6032–15 size has a maximum height of 1.5 mm, and the
V/7343–20 has a maximum height of 2.0 mm.
The T491 standard terminations are 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 with today's technology. Lead frame attachments to the
tantalum pellet are made via a microprocessor-controlled welding
operation, and a high temperature silver epoxy adhesive system.
Standard packaging of these devices is tape and reel in
accordance with EIA 481–1. This system provides perfect
compatibility with all tape-fed placement units.

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 specified 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.

Reverse Voltage
Solid tantalum capacitors are polar devices and may be permanently damaged or destroyed if connected with the wrong polarity. The
positive terminal is identified on the capacitor body by a stripe plus in some cases a beveled edge. A small degree of transient reverse
voltage is permissible for short periods per the table. The capacitors should not be operated continuously in reverse mode, even within
these limits.

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 desity 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.

T491 Industrial Grade MnO2 Series
Soldering Process
Note that although the X/7343–43 case size can withstand wave
soldering, the tall profile (4.3 mm maximum) dictates care in wave
process development.
Hand soldering should be performed with care due to the difficulty
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 reflow occurs. Once reflow occurs, the
iron should be removed immediately. “Wiping” the edges of a chip
and heating the top surface is not recommended.
During typical reflow operations, a slight darkening of the goldcolored epoxy may be observed. This slight darkening is normal
and not harmful to the product. Marking permanency is not
affected by this change.

KEMET’s families of surface mount capacitors are compatible
with wave (single or dual), convection, IR, or vapor phase reflow
techniques. Preheating of these components is recommended
to avoid extreme thermal stress. KEMET's recommended
profile conditions for convection and IR reflow reflect the profile
conditions of the IPC/J–STD–020D standard for moisture
sensitivity testing. The devices can safely withstand a maximum
of three reflow passes at these conditions.

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 fluctuations 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.

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 product–related 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.
