Note
* This datasheet provides information about parts that are
RoHS-compliant and / or parts that are non-RoHS-compliant. For
example, parts with lead (Pb) terminations are not RoHS-compliant.
Please see the information / tables in this datasheet for details.
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.

RoHS-COMPLIANT
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
rating. A decimal point
is indicated by an “R”
(6R3 = 6.3 V)
