Tantalum Surface Mount Capacitors – Standard Tantalum
T491 Industrial Grade MnO2
Overview
The KEMET T491, 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 T491 is classified as moisture sensitivity
level (MSL) 1 under J STD 020, with unlimited floor 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.
