PERFORMANCE CHARACTERISTICS

1.

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

rated DC voltage UR applied. + 85 °C to + 125° C with

499D only (see general information)

2.

Capacitance

and

Tolerance:

Capacitance

measured at 100 Hz and + 25 °C shall be within the

specified tolerance limits of the nominal rating.

Capacitance measurement shall be made by means

of a polarized capacitance bridge. No polarizing

voltage is required. The maximum voltage applied

during measurements shall be 0.5 volt rms at 100 Hz

and + 25 °C.

3.

Reverse Voltage: These capacitors are capable of

withstanding peak voltage in the reverse direction

equal to:

15 % of the rated DC voltage at + 20 °C

10 % of the rated DC voltage at + 25 °C

5 % of the rated DC voltage at + 85 °C

4.

Surge Voltage:

Capacitors shall withstand the surge voltage applied

in series with a 1000 ohm (± 5 %) resistor, at the rate

of one half-minute on, five and a half-minute off for

1000 successive test cycles at + 85 °C. After test,

capacitance change shall not exceed 10 % of initial

value, dissipation factor and DC leakage current shall

meet initial requirements at + 25 °C - Table 2.

6.

Life Test: After 2000 hours at + 85 °C with rated DC

voltage applied, or after 1000 hours at + 125 °C. With

derated DC voltage*, capacitors shall meet the

requirements in table below. (*only for 499D)

7.

Humidity Test: After 21 days (504 hours) * at

+ 40 °C, 90 to 95 % of relative humidity (per IEC

68-2-3) with no voltage applied, capacitors shall meet

the requirements in table below.

8.

Marking: The capacitors shall be marked with the

rated capacitance and the rated DC working voltage.

A code may be used for both capacitance and

voltage. Units rated at 6.3 volts are usually marked as

6 volts. The package shall be marked with full Vishay

Sprague part number, date code and quantity.
