Overview
The KEMET T494 is a lower ESR version of the popular
T491, designed specifically for today’s highly automated
surface mount processes and equipment. The T494
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 T494 is classified as MSL (Moisture
Sensitivity Level) 1 under J STD 020: unlimited floorlife
time at ≤ 30°C/85% RH. The T494 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-and-
reel in accordance with EIA 481. This system provides perfect
compatibility with all tape-fed placement units.
Benefits
• Meets or exceeds EIA Standard 535BAAC
• Taped and reeled per EIA 481
• Symmetrical, compliant terminations
• Optional gold-plated terminations
• Laser-marked case
• 100% surge current test on C, D, E, U, V, and X sizes
• Halogen-free epoxy
• Capacitance values of 0.1 μF to 1,000 μF
• Tolerances of ±10% and ±20%
• Voltage rating of 2.5 – 50 VDC
• Extended range values
• Low profile case sizes
• RoHS Compliant and lead-free terminations
• Operating temperature range of −55°C to +125°C
