General Specifications

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 at 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.

AC Voltage Applications:

The A-C component of the 225P's voltage rating

has been specified to assure that corona will not

be encountered when the capacitor is operated

within the noted specifications. We encourage

you to contact us if you have any concerns about

operating voltage, temperature limits, etc.

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.
