MINIATURE HIGH VOLTAGE CAPACITORS
520 SERIES
and up with 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. Please add
.010” to maximum T and W dimen-
sion for protective clear wrap.
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.
The unique high performance and
long life characteristics of polyester
account for the wide use of of this
miniature capacitor series. They can be
used in varied applications requiring
voltage ratings from 1000 to 10,000
VDC. Higher voltages are available on
special order. A wide range of sizes
and configurations are available. The
dielectric materials used are polyester
and kraft paper. You can choose from
axial-lead wrap and fill in oval and
round shapes.
These capacitors feature extended
foil construction for 1000V units and
tab construction for voltages 2000V

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.
