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 (only for types
CTS1, 749DX).
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. The polarizing voltage shall be of
2.2 volts. The maximum voltage applied during
measurements shall be 1.0 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 + 25 °C,
5 % of the rated DC voltage at + 85 °C.
4. Surge Voltage:
Table 1
Capacitors shall withstand the surge voltage applied in
series with a 1000 ohm resistor, at the rate of one
halfminute on, five and a half-minute off, for 1000
successive test cycles at + 85 °C or at + 125 °C. After
test, dissipation factor and leakage current shall meet
the initial requirements at + 25 °C (see below),
capacitance change shall not exceed ± 10 % of initial
value at + 25 °C.
5. Leakage current: Rated voltage UR shall be applied
to capacitors during five minutes with a resistor of
1000 ohm in series with each capacitor, before making
DC leakage current measurements. The leakage
current shall not exceed the following limits:
Table 2
6. Dissipation factor: The dissipation factor, when
measured at 100 Hz, shall not exceed the values
below:
Table 3
7. Stability at low and high temperature: Capacitance
change with temperature shall not exceed the limits of
the following table, leakage current and dissipation
factor shall be within the limits specified in Tables 2
and 3.
Table 4
8. Impedance: The impedance measured at 100 kHz
and 25 °C shall not exceed the following values:
Table 5
9. Life test: After 2000 hours at + 85 °C with rated DC
voltage applied, or after 2000 hours at + 125 °C with
category DC voltage applied (for types CTS1, 749DX
only) capacitors shall meet the requirements in table 6.
