PERFORMANCE CHARACTERISTICS

1.

Operating Temperature: Capacitors are designed to

operate over a temperature range of - 55 °C to + 200 °C.

Note

paragraph 9.3.

2.

DC Working Voltage: The DC working voltage is the

maximum operating voltage for continuous duty at the

rated temperature.

3.

Surge Voltage: The surge voltage rating is the

maximum voltage to which the capacitors should be

subjected

under

any

conditions.

This

includes

transients and peak ripple at the highest line voltage.

3.1 The surge voltage of capacitors is 115 % of rated DC

working voltage.

3.2 Surge Voltage Test: Capacitors shall withstand the

surge voltage applied through a 1000

 ± 10 % resistor

in series with the capacitor and voltage source at the

rate of one-half minute on, four and one-half minutes

off, for 1000 successive test cycles at + 85 °C or

+ 125 °C.

3.3 Following the surge voltage test, the capacitance at

+ 25 °C shall not have changed by more than ± 10 %

and the equivalent series resistance and DC leakage

current will not exceed the values shown in the

Standard Ratings table for each capacitor.

4.

Capacitance

Tolerance:

The capacitance of all

capacitors shall be within the specified tolerance limits

of the nominal rating.

4.1 Measurements shall be made by the bridge method at

or referred to a frequency of 120 Hz at a temperature of

+ 25 °C. The maximum voltage applied to the capacitors

accuracy of the bridge shall be within ± 2 %.

5.

Capacitance

Change

With

Temperature:

The

capacitance change with temperature shall not exceed

the values given in the Standard Ratings table for each

capacitor.

6.

Equivalent Series Resistance: Measurements shall be

made by the bridge method at, or referred to, a

frequency of 120 Hz at a temperature of + 25 °C. A

maximum

of

1

measurement.

6.1 The equivalent series resistance shall not exceed the

maximum value in ohms listed in the Standard Ratings

table for each capacitor.
