PERFORMANCE CHARACTERISTICS
1. Operating Temperature: - 55°C to + 85°C with rated DC
voltage U
R applied. + 85°C to + 125°C with linear voltage
derating to category voltage U
C for 499D only (see general
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
: 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.
