PCIM 2014 was the launch pad for AVX’s FM Series medium power film capacitors. The parts are non-inductively wound with dry, metallised polypropylene film dielectric and encapsulated in a flame retardant plastic case sealed with self-extinguishing, thermosetting epoxy resin. They feature RoHS-compliant double metallised polyester film electrodes in series construction, and exhibit high reliability at high current stress, high dv/dt capability, high moisture resistance, high capacitance stability, low losses, self-healing properties, and long useful lifetimes.

“These parts are principally designed for power supply, DC, and pulse applications, and are available in a wide range of case sizes, voltages, capacitance values, and tolerances, enabling their employment in an extensive range of end products,” said Gilles Terzulli, worldwide marketing manager, power film capacitors, AVX.

Rated for capacitance values spanning 0.01µF to 0.47µF, voltages spanning 250V to 2000V, and operating temperatures spanning -40°C to +105°C, applications are high frequency and high pulse rise-time circuits, high voltage power supplies, switch mode power supplies (SMPS), power converters, snubbers, and electronic lighting ballasts, such as compact florescent lamps and LEDs.

There are 17 case sizes (A-S) available, 14 voltages (250-2000V), three capacitance tolerances (±5%, ±10%, and ±20%), and two lead lengths (3.5mm and 22mm). Additionally, unlike aluminum electrolytic capacitors, FM Series film capacitors do not have a catastrophic failure mode. Instead, FM Series capacitors simply experience a parametric loss of capacitance of approximately 2% from their initial value, eliminating the risk of short circuit and enabling continued functionality.
