Film capacitors from AVX geared for DC filtering
AVX has revealed that its FFLC Series capacitors demonstrate higher specific energy than equivalent solutions (up to 240J/l) and feature the company's controlled self-healing technology. Available in large case sizes up to 35L, the devices claims to enable safe, high reliability, long lifetime performance with no risk of explosion.
Also available with a low stray-inductance option that tolerates high frequency ripple current, the series is geared for DC filtering in any variety of power conversion applications, but is particularly aimed at applications that require enhanced safety and reliability including: rail applications, such as main or auxiliary inverters; new energy applications, such as wind turbines and solar PV inverters; and industrial applications, such as motor drives.
Using metallised, segmented polypropylene film encased in unpainted, rectangular, resin-filled aluminium cases, FFLC Series capacitors have either four M8/15 female connections or four M12/30 male connections. Voltage ratings for the series span 800V to 1.35kV, capacitance values span 1750-20,600uF, and parasitic inductance values span 32-55nH. Exhibiting a ±10 per cent tolerance, FFLC Series capacitors feature a maximum RMS current value of up to 400A and an average lifetime of 100,000 hours at rated DC voltage, 70°C hot-spot temperature, and a <2 per cent change in capacitance value.
