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 V. The maximum voltage applied during
measurements shall be 1.0 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 + 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 W resistor, at the rate of 1.5 min on,
5.5 min 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 W 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
Note
(1) Not applicable for CTS13
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
Note
(1) Not applicable for CTS13
8. Impedance:
The impedance measured at 100 kHz and 25 °C shall not
exceed the following values:
Table 5
Note
(1) Not applicable for CR 0.68 μF
9. Life test:
After 2000 h at + 85 °C with rated DC voltage applied,
or after 2000 h at + 125 °C with category DC voltage
applied (for types CTS1, 749DX only) capacitors shall
meet the requirements in Table 6.
