DC-Link Film Capacitors
VX Corporation has launched the new FRC Series medium power DC-link film capacitors, which feature a wide range of capacitance and voltage values in addition to self-healing properties. Designed for use in DC filter circuits, power supplies, industrial inverters, UPS systems, motor drives, power converters, and solar inverters, FRC Series capacitors are comprised of dry, wound, metallized polypropylene film dielectric encased in a size A, self-extinguishing, cylindrical plastic case sealed with thermosetting resin and featuring four snap-in terminals that facilitate easy mounting to PCBs.
"The wide capacitance and voltage range of the new FRC Series polypropylene film capacitors, coupled with their self-healing capabilities and snap-in terminals for quick and easy PCB mounting, provide design engineers with several new high performance, high reliability capacitor solutions that will allow them to achieve a broad range of desired specs," said Gilles Terzulli, worldwide marketing manager, power film capacitors, AVX. FRC Series capacitors are available in nine voltages spanning 400V-1500V, two tolerances (±5% and ±10%), two lead lengths (4mm and 8mm), and with capacitance values spanning 4.7µF to 35µF. Housed in size A cylindrical cases measuring 54mm (L) x 36mm (OD) x 5.1mm (P1), the RoHS-compliant series is rated for operating temperatures spanning -40°C to +105°C and exhibits long lifetime performance of 100,000 hours at rated voltage and 70°C. Additionally, unlike aluminum electrolytic capacitors, FRC Series polypropylene film capacitors do not have a catastrophic failure mode. Instead, these capacitors simply experience a parametric loss of capacitance of approximately 5% from their initial value, eliminating the risk of short circuit and enabling continued functionality.
