To IEC 60068-1:
25/085/56 (25 °C/+85 °C/56 days damp heat test)
The capacitors can be operated in the temperature range of
40 °C to +85 °C but the impedance at 40 °C should be taken into
consideration.
Similar to CECC 30301-810
IEC 60384-4
Ripple current capability
Due to the ripple current capability of the contact elements, the following current upper limits must
not be exceeded:
Capacitor diameter
