PERFORMANCE CHARACTERISTICS
1. Operating Temperature: -55 °C to +85 °C with rated DC
voltage UR applied. +85 °C to +125° C with linear voltage
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
voltage applied during measurements shall be 0.5 VRMS
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
(1) For 499D
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.
7. Humidity Test: after 21 days (504 h) (1) 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.
Note
(1) Humidity test is 56 days (1350 hours) for 499D
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:
