Polypropylene Film Capacitors

ORANGE DROP

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 ≤ .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.

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%.

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.

Not more than one failure allowed in 12 units tested.

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

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.

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.

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

60Hz voltage for a period of 500 hours at + 85°C.
