Polypropylene Film Capacitors
ORANGE DROP®, Low Loss
PolypropyleneplasticfilmisemployedasthedielectricinType
715P ORANGE DROP® capacitors. Type 715P capacitors
are ideal for applications where high AC current flow is found,
as in certain solid-state TV vertical circuits,
r-f generators and pulse-forming networks where dielectric
heating is often a problem.
The polypropylene dielectric film is similar to polystyrene in
that it can handle high AC currents due to its low loss but with
the added advantage of an operating temperature to
+ 105°C.
Capacitance change with temperature is less than 3% over
the entire operating temperature range. The temperature
coefficient is negative and virtually linear at 180PPM/°C over
thetemperaturerangeof+25°Cto+105°C. Thischaracteristic

Type 715P ORANGE DROP® capacitors are conformally
coated with a flame retardant epoxy.

PERFORMANCE CHARACTERISTICS
Operating Temperature: - 55°C to + 85°C standard; up to
+ 105°C when working voltage is reduced to 50% of the
+ 85°C rating.
Humidity Test: Condition capacitors with no voltage
applied for 72 hours at 95% relative humidity and + 75°C.
Remove capacitors from humidity chamber, wipe surface
dry of moisture and dry in circulating air for 4 hours.
Measure insulation resistance after a two minute charge at
+ 25°C and rated voltage or 500 VDC, whichever is less.
Minimum product of insulation resistance and capacitance
shall be 50,000 Megohm-microfarads after test but need
not exceed 100,000 Megohm. Not more than one failure
in 12 units tested shall be permitted.
Insulation Resistance: After a 2 minute charge at rated
voltage or 500 V, whichever is less.
At + 25°C: 400,000 Megohm for C ≤ .5µF.
200,000 Megohm - Microfarads for C > .5 Microfarads.
At + 85°C: 20,000 Megohm for C ≤ .5 Microfarads.
10,000 Megohm - Microfarads for C > .5 Microfarads.
At + 105°C: 2000 Megohm for C ≤ .5µF.
1000 Megohm - Microfarads for C > .5 Microfarads.
DC Life Test: Capacitors are capable of withstanding a
500 hour life test at + 85°C at 150% of rated working
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 the initial limit
and dissipation factor shall not have increased to more
than 0.1%.
Capacitance, Tolerance and Dissipation Factor:
Capacitors shall be measured at a frequency of 1000Hz
at + 25°C or else be referred to measurements made at
that frequency and temperature. The maximum dissipation
factor shall be 0.1%.
AC Life Test: Capacitors shall withstand the maximum
60Hz voltage for a period of 500 hours at + 85°C.
Dielectric Withstanding Voltage: Capacitors rated below
1000 volts shall withstand a DC potential of 250% of rated
voltage applied between terminals for not more than
5 seconds. Capacitors rated 1000 volts and above shall
withstand a DC potential of 200% of rated voltage applied
between the terminals for not more than 5 seconds. The
test voltage must be applied and discharged through a
resistor of one ohm per volt.
