PDF《Medium Power Film Capacitors》

Medium Power Film Capacitors FFV3 (RoHS Compliant) The series uses a non-impregnated metallized polypropylene or polyester dielectric, with the controlled self-healing process, specially treated to have a very high dielectric strength in oper- ating conditions up to 105°C.

The FFV3 has been designed for printed circuit board mounting. DC FILTERING

STANDARDS IEC 61071-1, IEC 61071-2: Power electronic capacitors IEC 60384-16: Fixed metallized polypropylene film dielectric DC capacitors IEC 60384-16-1: Fixed metallized polypropylene film dielectric DC capacitors Assessment level E IEC 60384-17: Fixed metallized polypropylene film dielectric AC and pulse capacitors IEC 60384-17-1: Fixed metallized polypropylene film dielectric AC and pulse capacitors Assessment level E IEC 60384-2: Fixed metallized polyester capacitors 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. PACKAGING MATERIAL Self-extinguishing plastic case (V0 = in accordance with UL 94) filled thermosetting resin. Self-extinguishing thermosetting resin (V0 = in accordance with UL 94;

I3F2 = in accordance with NF F 16-101). HOT SPOT CALCULATION See Hot Spot Temperature, page 3. θhot spot = θambient + (Pd + Pt) x (Rth + 7.4) θhot spot = θcase + (Pd + Pt) x Rth with Pd (Dielectric losses) = Q x tgδ0 ? [
