PERFORMANCE CHARACTERISTICS
Operating Temperature:
-55 °C to +85 °C
(to +125 °C with voltage derating)
Capacitance Tolerance:
at 120 Hz, +25 °C. ± 20 %
standard. ± 10 %, ± 5 % available as special
DC Leakage Current (DCL Max.):
at +25 °C and above:
leakage current shall not exceed the
values listed in the Standard Ratings tables
APPLICATIONS
Designed specifically for the severe operating environment
of aerospace applications, this capacitor was developed
under partial sponsorship of the Marshall Space Flight
Center, National Aeronautics and Space Administration. To
meet aerospace requirements, the capacitors have a high
resistance to damage from shock and vibration.
