1 / 4 page 1 Medium Power Film Capacitors FE (RoHS Compliant) The FE series uses a non-impregnated metallized polypropylene dielectric specially treated to have a very high dielectric strength in operating conditions up to 100°C. The FE has been designed for printed circuit board mounting. FE series performance characteristics make them a viable alternative to aluminum electrolytic technology due to much lower ESR and much higher surge voltage capability (dv/dt). APPLICATIONS The FE capacitor is particularly designed for DC filtering, low reactive power. HOT SPOT CALCULATION See Hot Spot Temperature, page 3. θhot spot = θambient + (Pd + Pt) x Rth with Pd (Dielectric losses) = Q x tg δ0 Q x tg δ0 ⇒ [ 1⁄2 x Cn x (Vpeak to peak)2 x f ] x tgδ0 tg δ0 (tan delta) For polypropylene, tg δ0 = 2 x 10-4 for frequencies up to 1MHz and is independent of temperatures. Pt (Thermal losses) = Rs x (Irms)2 where Cn in Farad Irms in Ampere f in Hertz Vin Volt Rs in Ohm θ in °C Rth in °C/W OPERATING TEMPERATURE RANGE Operating temperature range: -40ºC to +100ºC LIFETIME EXPECTANCY One unique feature of this technology (versus aluminum electrolytics) is how the capacitor reacts at the end of its lifetime. Unlike aluminum electrolytic film capacitors do not have a catastrophic failure mode. Film capacitors simply experience a parametric loss of capacitance of about 2% from initial value, with no risk of short circuit. 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).
