Tantalum Surface Mount Capacitors Low ESR
T494 Industrial Grade MnO
2
Overview
The KEMET T494 is a lower ESR version of the popular
time at 30C/85% RH. The T494 standard terminations are
T491, designed specifically for today s highly automated
available in 100% matte tin and provide excellent wetting
surface mount processes and equipment. The T494
characteristics and compatibility with today's surface mount
combines KEME Ts proven solid tantalum technology,
solder systems. Tin/lead (Sn/Pb) terminations are available
acclaimed and respected throughout the world, with the
upon request for any part number. Gold-plated terminations
latest in materials, processes and automation, resulting
are also available for use with conductive epoxy attachment
in unsurpassed total performance and value. This product
processes. Standard packaging of these devices is tape-and-
meets or exceeds the requirements of EIA standard reel in accordance with EIA 481. This system provides perfect
535BAAC. The T494 is classified as MSL (Moisture compatibility with all tape-fed placement units.
