Encapsulation:
Solvent-resistant, flame-retardant plastic
case with epoxy resin seal, UL 94 V-0
Terminations:
Tinned wire or plates.
Marking:
Colour: Red. Marking: Black.
Epoxy resin seal: Red
for pulses equal to the rated voltage
Mounting Recommendation
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. 5 Nm.
For further details and graphs please
refer to Technical Information.
