Electrical Data
Capacitance
range: 0.047 μF to 25 μF
Rated voltages: 250VDC,
400VDC, 630VDC, 1000VDC, 1600VDC, 2000VDC,
3000VDC Capacitance
tolerances: ±20%, ±10%, ±5% (other
tolerances are available subject to special
enquiry) Operating temperature
range: -55°C to
+100°C Climatic test
category: 55/100/56 in accordance with
IEC Insulation resistance at
+20°C: C < 0.33 μF: > 1 x
105 M (mean
value: 5 x 105 M) C
> 0.33 μF: > 30000 sec (MxμF) (mean value: 100000
sec) Measuring voltage: 100V/1
min. Dissipation factors at
+20°C: tan
Test voltage:
L < 41.5: 1.6 Ur, 2 sec L =
41.5: 1.4 Ur, 2 sec L = 56 : 1.2 Ur, 2
sec Voltage derating: A voltage derating factor of
1.35% per K must be applied from +85°C for DC
voltages and from +75°C for AC
voltages. Reliability: Operational
life > 300000 hours Failure rate < 1 fit
(0.5 x Ur and 40°C)
Excessive mechanical
strain, e.g. pressure or shock onto the capacitor body,
is to be avoided during mounting and usage of the
capacitors. When fixing the plates the screw torque is
to be limited to max. 5Nm.
