METALLIZED POLYPROPYLENE CAPACITORS
935 SERIES
Polypropylene and foil capacitors may
also be specified in all standard styles.
All capacitors feature extended foil
construction and standard tin-coated
copper-clad steel leads. Nickel, copper,
dumet and other special leads are available.
Protective clear wrap is offered on all
wrap and fill units.
The potting material and endfills
of Electrocube’s capacitors meet or
exceed the flammability requirements
of UL94VO.
Dimensional variations for all MFD
values are available with the same volume
to meet your design requirements.
This capacitor series was designed for
AC and pulsing applications. The units
are rated for 135 VRMS and 67 VRMS
(to 400 Hz), but may also be used for all
DC applications up to 200 VDC and
400 VDC respectively.
A wide range of sizes and styles is
available. You can choose from axial-
lead wrap and fill in oval and round
configurations or rectangular epoxy
case with axial and radial leads.
Two types of dielectric material are
used: metallized polypropylene and
polypropylene and foil. Metallized
versions are offered in all styles.

NOTES:
For information regarding insulating sleeves, mountings, special terminals,
non-standard leads, circuit connections and other hardware, please
consult factory.
For styles and ratings not shown, or for unusual requirements necessitated
by special circuit applications (including higher IR or lower DF), consult
the factory direct.
All Electrocube film capacitors have endfills and tape that
meet or exceed the flammability requirements of UL94V0.
