SMPS Stacked MLC Capacitors
(SM Style) SM Military Styles MIL-PRF-49470
drawing 87+06 capacitors. MIL-PRF-49470 specification
was created to produce a robust replacement for DSCC
87+06. MIL-PRF-49470 offers two product levels.
AVX IS QUALIFIED TO MIL-PRF-49470/1
AND MIL-PRF-49470/2
The SMPS capacitors are designed for high currentꢁ 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.
AꢄX is qualified to supply MIL-PRF-49470ꢀ+ parts. These are
unencapsulated ceramic dielectricꢁ switch mode power supply
capacitors. AꢄX is also qualified to supply MIL-PRF-49470ꢀ1
parts. These are encapsulated ceramic dielectricꢁ switch
mode power supply capacitors.
MIL-PRF-49470 SMPS Series capacitors are primarily used
in inputꢀoutput 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 -ꢂꢂ/C to ꢃ+1ꢂ/C.

For “T” level partsꢁ replace the “M” in the pin with “T” (for
example M49470R0+474KCN becomes T49470R0+474KCN)
MIL-PRF-49470 contains additional capacitors that are not
available in 87+06ꢁ such as additional lead configurations
and lower profile parts.
