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.

* Pb containing terminations are not RoHS compliant, exemptions may apply

This is expressed

in picofarads. The

first two digits are

the significant

figures. The third

is the number of

zeros to follow

X0 = ± 20 %

X9 = ± 10 %

X5 = ± 5 %

This is expressed in

volts. To complete the

three-digit block, zeros

precede the voltage

Note

Packaging: The use of formed plastic trays for packaging this type of axial lead component is standard. Tape and reel is not recommended due

to the unit weight.
