Applications
Typical applications include decoupling , filtering and hold-up in defense and aerospace applications that require low ESR or
a benign failure mode.
When extreme temperatures and humidity are taken into account, polymer capacitors offer a number of advantages over
other types of capacitors. KEMET continues to investigate the behavior of polymer capacitors in extreme conditions. If
you have questions about using these capacitors in a specific environment or application, we suggest you contact your
local KEMET representative or Field Application Engineer. You may also refer to Considerations for Polymer Capacitors in
Extreme Environments located at www.kemet.com/ExtremePolymerPaper.
