The FM Series medium power film capacitors from AVX Corp. are non-inductively wound with dry, metallized polypropylene film dielectric encapsulated in a flame-retardant plastic case. They are sealed with self-extinguishing, thermosetting epoxy resin and featuring RoHS-compliant double metallized polyester film electrodes in series construction. The FM Series capacitors 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. Rated for capacitance values spanning 0.01 µF to 0.47 µF, voltages spanning 250 V to 2000 V, and operating temperatures spanning -40 °C to +105 °C, the new FM Series capacitors are designed for 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. AVX's FM Series medium power film capacitors are available in 17 case sizes (A-S), 14 voltages (250-2000V), three capacitance tolerances (±5%, ±10%, and ±20%), and two lead lengths (3.5 mm and 22 mm). 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. Lead time for the series is approximately eight weeks.
