PERFORMANCE CHARACTERISTICS

1. Operating Temperature: - 55°C to + 85°C with rated DC

voltage U

derating to category voltage U

information)

2. Capacitance and Tolerance: Capacitance measured at

100Hz 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

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.

* Humidity test is 56 days (1350 hours) for 499D

8. Marking

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
