Technical content

Medium Power Film Capacitors FLB (RoHS Compliant) The FLB series uses metallized polypropylene dielectric, alu- minum can, impregnated with soft PU specially treated to have a very high dielectric strength in operating conditions up to 85°C. The FLB has been designed with overpressure disconnected device. They are suitable for power factor correction and out- put AC filtering for power converters, UPS systems, solar inverters and motor drives etc.

APPLICATIONS

  • The FLB capacitor is particularly designed for AC filtering and power factor correction. HOT SPOT CALCULATION See Hot Spot Temperature, page 2. θhot spot = θambient + (Pd + Pt) x Rth with P d (Dielectric losses) = Q x tgδ0 Q x tgδ0 ⇒ [ 1⁄2 x Cn x (Vpeak to peak)2 x f ] x tgδ0 tgδ0 (tan delta) For polypropylene, tgδ0 = 2 x 10-4 for frequencies up to 1MHz and is independent of temperatures. Pt (Thermal losses) = Rs x (Irms)2 where C n in Farad I rms in Ampere f in Hertz Vi n V o l t R s in Ohm θ in °C Rth in °C/W WORKING TEMPERATURE According to the power to be dissipated – -40°C to +85°C LIFETIME EXPECTANCY One unique feature of this technology (as opposed to alu- minum electrolytic) 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 5% from initial value, with no risk of short circuit. The capacitor continues to be functional even after this 5% decrease.
