FRC series capacitors are comprised of dry, wound, metallised 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.
FRC series capacitors are available in nine voltages spanning 400V-1500V, two tolerances (±5% and ±10%), two lead lengths (4 mm and 8 mm), and with capacitance values spanning 4.7 µF to 35 µF. Housed in size A cylindrical cases measuring 54 mm (L) x 36 mm (OD) x 5.1 mm (P1), the 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. The wide capacitance and voltage range coupled with their self-healing capabilities and snap-in terminals provide design engineers with additional high performance, high reliability capacitor solutions, the company says.
Unlike aluminium electrolytic capacitors, polypropylene film capacitors do not have a catastrophic failure mode. Instead, these capacitors experience a parametric loss of capacitance of approximately 5% from their initial value, eliminating the risk of short circuit and enabling continued functionality.
