Tantalum Surface Mount Capacitors – MIL-PRF (CWR Style)
T409 MIL-PRF-55365/4 (CWR09 Style)
Overview
The KEMET T409 is approved to MIL-PRF-55365/4 (CWR09
Style) with Weibull failure rates of B level (0.1% failures
per 1,000 hours), C level (0.01% failures per 1,000 hours),
D level (0.001% failures per 1,000 hours), or T level (0.01%
failures per 1,000 hours, option C surge current, DPA,
radiographic inspection, 100% visual inspection, DCL and
ESR measurements within +3 standard deviations, and Group
C inspection). This CWR09 product is a precision-molded
device, with compliant terminations and indelible laser
marking. Tape & Reel packaging per EIA 481 are standard.
