HIGH CURRENT/HIGH FREQUENCY
METALLIZED POLYPROPYLENE
945 SERIES
Units are available in axial-lead wrap
and fill, in oval and round shapes, and in
voltages of 100, 200, 400 and 600 VDC.
All capacitors feature extended foil
construction and standard tin-coated
copper leads.
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.
The new rugged Series 945 metallized
capacitors offer high frequency opera-
tion, high current and low ESR in a
miniature package. They are able to
handle high surge currents without
degrading thus making them an
excellent electrolytic capacitor replace-
ment. Series 945 are ideal for audio
systems. This capacitor series was
designed for AC and pulsing appli-
cations. The units are rated for 67
VRMS and 100 and 270 VRMS (to 100
KHz), but may also be used for all DC
applications up to 200 VDC and 400
VDC respectively.
SPECIFICATIONS
Temperature:
-55°C to +85°C at rated voltage; to +105°C
with 50% voltage derating.
Dielectric Voltage Test:
Will withstand the application of 150 VDC,
300 VDC, 600 VDC and 900 VDC on 67 VAC, 135 VAC, 270 VAC and
440 VAC, respectively at 25° C for a period not to exceed 1 minute;
current limited to 5 mA.
DC Life Tests:
Will withstand the application of 138 VDC, 280 VDC,
560 VDC and 840 VDC, respectively, on the 67 VRMS, 135 VRMS,
270 VRMS and 440 VRMS parts at 105°C for 250 hrs., with not
more than 1 failure in in 12 permitted, current limited to 5 mA.
For life test details, contact the factory.

Shall not exceed 0.1%
at 25°C for values to 1 mfd; 0.2% for
values 1 mfd and over.
Dielectric Absorption:
Shall not
exceed 0.1% at 25°C per MIL-C-19978.
Acceptance Criteria:
Measurement
frequency for capacitance and
dissipation factor shall be 1000 Hz
for values up to 1 mfd and 120 Hz
for values of 1 mfd and over.

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.
