Type 715P
Vishay Sprague
Polypropylene Film Capacitors
ORANGE DROP
®
, Low Loss
Polyproplyene plastic film is employed as the
dielectric in Type 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.
RoHS
COMPLIANT
The polyproplyene dielectric film is similar to polystyrene in
that it can handle high AC currents due to is 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 180 PPM/°C over
the temperature range of + 25 °C to + 105 °C. This
characteristic means the Type 715P is suitable for matching
with positive TC resistors and inductors to maintain circuit
stability.
Type 715P ORANGE DROP
®
capacitors are conformally
coated with a flame retardant epoxy.
Performance characteristics, as well as curves showing
typical variation in electrical characteristics as a function of
temperature and frequency, are given.
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.
Insulation Resistance:
After a 2 minute charge at rated
voltage or 500 V, whichever is less.
At + 25 °C: 400 000 Megohm for C
≤
0.5 µF
200 000 Megohm - Microfarads for C > 0.5 Microfarads
At + 85 °C: 20 000 Megohm for C
≤
0.5 Microfarads
10 000 Megohm - Microfarads for C > 0.5 Microfarads
At + 105 °C: 2000 Megohm for C
≤
0.5 µF
1000 Megohm - Microfarads for C > 0.5 Microfarads
Capacitance Tolerance and Dissipation Factor:
Capacitors shall be measured at a frequency of 1000 Hz at
+ 25 °C or else be referred to measurements made at that
frequency and temperature. The maximum dissipation factor
shall be 0.1 %.
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. Capacitance 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 1 ohm per volt.
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.
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 %.
AC Life Test:
Capacitors shall withstand the maximum
60 Hz voltage for a period of 500 hours at + 85 °C.
