U.S. Preferred Styles
drawing 87106 capacitors. MIL-PRF-49470 specification
was created to produce a robust replacement for DSCC
87106. MIL-PRF-49470 offers two product levels.
AVX IS QUALIFIED TO MIL-PRF-49470/01
AND MIL-PRF-49470/02
The SMPS capacitors are designed for high current, high-
power and high-temperature applications. These capacitors
have very low ESR (Equivalent Series Resistance) and ESL
(Equivalent Series Inductance). SMPS Series capacitors offer
design and component engineers a proven technology
specifically designed for programs requiring high reliability
performance in harsh environments.
Level “B” is the standard reliability. Level “T” is the high relia-
bility suitable for space application.
AVX is qualified to supply MIL-PRF-49470/01 parts. These
are unencapsulated ceramic dielectric, switch mode power
supply capacitors. AVX is also qualified to supply MIL-PRF-
49470/02 parts. These are encapsulated ceramic dielectric,
switch mode power supply capacitors.
MIL-PRF-49470 SMPS Series capacitors are primarily used
in input/output filters of high-power and high-voltage power
supplies as well as in bus filters and DC snubbers for high
power inverters and other high-current applications. These
capacitors are available with through-hole and surface
mount leads. The operating temperature is -55°C to +125°C.

For “T” level parts, replace the “M” in the pin with “T” (for
example M49470R01474KCN becomes T49470R01474KCN)
MIL-PRF-49470 contains additional capacitors that are not
available in 87106, such as additional lead configurations
and lower profile parts.
