AVX’ FLB series medium power film capacitors come packaged in a cylindrical aluminium can with terminals that enable direct, three-phase, internal wire connection. FLB series capacitors are fabricated with metallised polypropylene dielectric combined with a soft polyurethane resin. FLB series capacitors feature a dual safety system consisting of an overpressure disconnector and self-healing technology, as well as exhibiting high ripple current and extremely high dielectric strength in operating temperatures spanning -40°C to +80°C. Applications for the series include: power factor correction and output AC filtering in power converters, UPS systems, solar and wind inverters, and motor drives.
The FLB series of three-phase, medium power film capacitors are available in nine case sizes, six voltages spanning 230-690VAC, capacitance values spanning 3*20.3µF to 3*335µF, and three capacitance tolerances (±5%, ±10%, ±20%). Optimised for AC voltage performance, the series also exhibits high overvoltage capabilities as a result of its self-healing properties. Additionally, unlike aluminium electrolytic capacitors, FLB series polypropylene capacitors do not have a catastrophic failure mode, as film capacitors simply experience a parametric loss of capacitance of approximately 5%, which both negates the risk of short-circuiting and enables continued functionality. Lifetime for the series is 100,000 hours at rated voltage and 70°C.
