Dissipation factors at
+20°C: tan
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) Specific dissipation:

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.
