DC Working Voltage: The DC working voltage is the

maximum operating voltage for continuous duty at the

rated temperature.

3.

Surge Voltage: The surge DC rating is the maximum

voltage to which the capacitors may be subjected

under any conditions, including transients and peak

ripple at the highest line voltage.

3.1

Surge Voltage Test: Capacitors shall withstand the

surge voltage applied in series with a 33 ohm ± 5%

resistor at the rate of one-half minute on, one-half

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

PERFORMANCE CHARACTERISTICS

and the leakage current shall meet the initial require-

ments; the capacitance shall not have changed

more than ± 10%.

4.

Capacitance Tolerance: The capacitance of all

capacitors shall be within the specified tolerance

limits of the normal rating.

4.1

Capacitance measurements shall be made by means

of polarized capacitance bridge. The polarizing

voltage shall be of such magnitude that there shall be

no reversal of polarity due to the AC component.

The maximum voltage applied to capacitors during

measurement shall be 2 volts rms at 120 Hz at

+ 25°C. If the AC voltage applied is less than one-

half volt rms, no DC bias is required. Accuracy of the

bridge shall be within ± 2%.

5.

Capacitance Change With Temperature: The

capacitance change with temperature shall not

exceed the following percentage of the capacitance

measured at + 25°C:

6.

Dissipation Factor: The dissipation factor,

determined from the expression 2πfRC, shall not

exceed values listed in the Standard Ratings Table.

6.1

Measurements shall be made by the bridge method

at, or referred to, a frequency of 120 Hz and a

temperature of + 25°C.
