Polyester Capacitors

FEATURES

• Utilizes minimum area where printed wiring

board space is most important

• Wound from PETP polyester film and thin gauge

foil

under

carefully

controlled

atmospheric

conditions

• Protected against moisture by a conformal coating of

epoxy

• Specifically designed for printed wiring board applications

• Widely

used

in

computers,

instrumentation

and

telecommunications equipment

• 100 VDC through 600 VDC, may be operated up to

+ 125 °C with proper dearting

PERFORMANCE CHARACTERISTICS

Operating Temperature: - 55 °C to + 85 °C

To + 105 °C when working voltage is reduced to 70 % of

+ 85 °C rating; to + 125 °C when working voltage is reduced

to 50 % of 85 °C rating

Insulation Resistance: After a 2 minute charge at rated

voltage or 500 V, whichever is less.

At + 25 °C: 100 000 Megohm for C

≤ 0.25 Microfarads

25000 Megohm - Microfarads for C > 0.25 Microfarads

At + 85 °C: 10 000 Megohm for C

≤ 0.15 Microfarads

1500 Megohm - Microfarads for C > 0.15 Microfarads

At + 105 °C: 1500 Megohm for C

≤ 0.17 Microfarads

250 Megohm - Microfarads for C > 0.17 Microfarads

At + 125 °C: 200 Megohm for C

≤ 0.13 Microfarads

25 Megohm - Microfarads for C > 0.13 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 0.75 %

Dielectric Withstanding Voltage:

Capacitors shall withstand a DC potential of 250 % of rated

voltage applied between 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 2 minute charge at 25 °C and rated voltage or 500 VDC,

whichever is less. Minimum product of insulation resistance

and capacitance shall be 5000 Megohm - Microfarads after

test but need not exceed 10 000 Megohm. Not more than

one failure allowed in 12 units tested.

DC Life Test:

Capacitance 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 1 %.
