1 / 4 page 1 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 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 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. PACKAGING MATERIAL • Aluminum can with soft PU STANDARDS IEC 61071-1, IEC 61071-2: Power electronic capacitors IEC 60831: Shunt power capacitors of selfhealing type for ac systems having a rated voltage up to and including 1kv HOW TO ORDER FLB Series A Case A B C D E F G H J 6 Dielectric 6 = Polypropylene V Voltage A = 230V I = 400V L = 440V J = 525V N = 660V O = 690V 0335 Capacitance EIA Code 0103 = 0.01μF K Tolerances J = ±5% K = ±10% 03 Terminal Code 03 = 3 phase |
