AVX Corporation has introduced the new FLA Series medium power film capacitors. Comprised of metallized polypropylene dielectric imbued with a soft polyurethane (PU) resin and encased in a cylindrical aluminum can with fast-on or screw terminals, FLA Series capacitors exhibit high ripple current and extremely high dielectric strength in operating temperatures spanning -40 to +80 degrees C. Specifically designed for ac filtering in power converters including; UPS systems, solar and wind inverters, and motor drives, the 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, AVX.
Available in nine case sizes spanning A I, eight voltages spanning 250690Vac, capacitance values spanning 10µF to 600µF, and two capacitance tolerances (±5% and ±10%), FLA Series medium power film capacitors are optimized for ac voltage performance and exhibit high overvoltage capabilities as a result of their self-healing properties.
Additionally, unlike aluminum 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 degrees C. Lead time for the series is approximately eight weeks.
