Tantalum Surface Mount Capacitors – Automotive
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 serie conform to this global standard.
Five low profiles case sizes are available 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. The symmetrical terminations offer total compliancy
to provide the thermal and mechanical stress relief required with
today's technology. 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.
