Tantalum Surface Mount Capacitors – High Reliability COTS (CWR11 Style)

T493 Series Military/Aerospace COTS MnO

Overview

The KEMET T493 Series is designed for the COTS

(Commercial Off-the-Shelf) requirements of military and

aerospace applications. This series is a surface mount product

offering various lead-frame plating options, Weibull grading

options, and surge current testing options. Standard, low, and

ulta-low ESR options are available. All lots of this series are

conditioned with MIL–PRF–55365 Group A testing. This series is

also approved for DSCC Drawing 07016 (please see part number

list specific to this drawing).
