METALLIZED POLYESTER
PLASTIC CASE, QUICK DISCONNECT CAPACITORS
247A SERIES
mounting configurations, voltages
and capacitances for capacitor models
not shown. Special designs can be
manufactured to meet any existing or
future requirement.
For specific information on your
product needs, contact your local
sales representative or Electrocube
directly.
The potting material and epoxy
endfills of Electrocube’s capacitors
meet or exceed the flammability
requirements of UL94VO.
The 247A Series Snubber Capacitors
were designed for AC applications
such as motor start, motor run,
fluorescent lamp ballast and other
commercial applications. A wide
range of rectangular epoxy case sizes
are available with quick disconnect
terminals. Wrap and fill designs are
also available on special order.
Extended metallized polyester is
used as the dielectric material.
Electrocube recognizes and supports
the circuit design needs for specific
Dimensional variations for all
MFD values are available with the
same volume to meet your design
requirements.
SPECIFICATIONS
Capacitance Tolerance:
±10%
Temperature:
-55°C to +70°C at rated voltage
Dielectric Voltage Test:
Will withstand the application of
175% rated DC voltage for a period not to exceed 1 minute at
25°C; current limited to 5 mA.
TYPICAL DIELECTRIC CHARACTERISTIC CURVES
DC Life Test:
Will withstand the application of 125% rated VDC at
85°C for 1000 hours, with not more than 1 failure in 12 permitted;
current limited to 5 mA
Dissipation Factor:
Shall not exceed .35% at 25°C.
Acceptance Criteria:
Measurement frequency for capacitance
and dissipation factor shall be 1000 Hz for values less than 1 mfd
and 120 Hz for values of 1.0 mfd and up.
Insulation Resistance:
At rated voltage or 500V, whichever
is less, units shall meet the minimum values below:
1.0K
Terminals:
1/4” Quick Disconnect terminals
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.
INSULATION RESISTANCE
(MEGOHMS TIMES MICROFARADS)
The 247A Series film capacitors have epoxy fill and enclosures
that meet or exceed the flammability requirements of UL94V0.
