PERFORMANCE CHARACTERISTICS

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

derating to category voltage UC for 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

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:

Note

Capacitors shall withstand the surge voltage applied in

series with a 1000

 (± 5 %) resistor, at the rate of 1.5 min

on, 5.5 min 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 h at +85 °C with rated DC voltage

applied, or after 1000 h at +125 °C. With derated DC

voltage (only for 499D), capacitors shall meet the

requirements in table below.

to 95 % of relative humidity (per IEC 68-2-3) with no

voltage applied, capacitors shall meet the requirements

in table below.

Note

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 part number,

date code, and quantity.

5. Stability at low and high temperatures:
