Medium Power Film Capacitors

FFV3 (RoHS Compliant)

The series uses a metallized polypropylene or polyester dielec-

tric, with the controlled self-healing process, specially treated

to have a very high dielectric strength in operating conditions

up to 105°C.

This is a dry solution for polypropylene and dry or wet for

polyester.

The FFV3 has been designed for printed circuit board mounting.

LIFETIME EXPECTANCY

One unique feature of this technology (as opposed to elec-

trolytics) is how the capacitor reacts at the end of its lifetime.

Unlike aluminum, electrolytics film capacitors do not have a

catastrophic failure mode. Film capacitors simply experience

a parametric loss of capacitance of about 2%, with no risk of

short circuit.

Please note that this is theoretical, however, as the capacitor

continues to be functional even after this 2% decrease.
