AVX, a manufacturer of passive components and interconnect solutions, has introduced the new FLA Series medium power film capacitors. Comprised of metalised polypropylene dielectric imbued with a soft polyurethane (PU) resin and encased in a cylindrical aluminium can with fast-on or screw terminals, FLA Series capacitors exhibit high ripple current and extremely high dielectric strength in operating temperatures spanning -40°C up to +80°C. Specifically designed for AC filtering in power converters, UPS systems, solar and wind inverters, and motor drives, new FLA Series capacitors exhibit high-reliability, single-phase performance, as well as feature self-healing technology and an internal overpressure disconnector device.
The new FLA Series film capacitors were specifically designed with self-healing properties and an internal overpressure disconnector to provide our customers in the various power conversion markets with a high-reliability, long-lasting component ideal for AC filtering, said Gilles Terzulli, worldwide marketing manager, power film capacitors at AVX.
Available in nine case sizes spanning A to I, eight voltages spanning 250 to 690VAC, capacitance values spanning 10F to 600F, and two capacitance tolerances (5% and 10%), FLA Series medium power film capacitors are optimised for AC voltage performance and exhibit high overvoltage capabilities as a result of their self-healing properties. Additionally, unlike aluminium electrolytic capacitors, FLA 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 RoHS-compliant series is 100,000 hours at rated voltage and 70°C. Lead time for the series is approximately eight weeks.
