General Specifications
The Type 225P Orange Drop
®
is designed and manufactured for operation in a wide range of demanding envi-
ronments and applications. Type 225P capacitors are wound from the most reliable polyester film and alum-
inum foil available and are protected by a rugged conformal coating of orange epoxy. They may be operated
up to +125 °C with proper derating.
The combination of proven dependability and extensive availability through CDE distribution make
the 225P an ideal choice for many commercial and industrial electronic applications, from power supplies and
instrumentation to audio amplifiers and test equipment.
Operating Temperature Range:
The standard operating temperature range for
polyester film is -55°C to +85°C. The 225P
may be operated a t full voltage within this
temperature range.
The 225P may be operated up to +105°C
provided the DC working voltage is reduced
to 70% of the +85°C rating (full rating), and
up to +125°C with a 50% reduction from the
+85°C rating (full rating).
For more specific details regarding operation
above +85°C please contact our design
engineering department.
The maximum operating temperature for the
225P polyester film capacitors is +125°C.
Dielectric Withstanding Voltage:
Units shall withstand a DC potential of 250%
of rated voltage applied between terminals for
not more than 5 seconds.
Lead Bend Test:
After 3 consecutive 180° bends. No damage.
Humidity Testing:
Units subjected to 95% relative humidity for 72
hours with no voltage applied at +75°C. After 4
hours of drying minimum product of insulation
resistance and capacitance shall be 5,000 M -µF.
DC Voltage Life Test:
500 hours at +85°C at 150% of rated voltage. After
test; capacitance shall not have changed by more
than ±5% of initial value, insulation resistance shall
not have decreased by more than 50% of initial value
and dissipation factor shall not have increased to
more than 1.0%. In addition, there should be no
open or short circuits, and no sign of visible damage.
