AVX FFLI Series film capacitors

AVX Corporation has released a high-voltage series of dry, medium-power film capacitors for DC filtering applications, such as the DC filtering of high-frequency ripple currents and decoupling DC links in AC/AC and DC/AC motor drive inverters.

Rated for 1.5 to 3 kV, the FFLI Series capacitors comprise a combination of dry, metallised polypropylene film and a no-free-oil solution sealed in a cylindrical aluminium case filled with self-extinguishing polyurethane resin. This composition equips the series with controlled self-healing technology that prevents potential explosions resulting from the avalanche effect, enables a benign failure mode consisting exclusively of capacitance losses and ensures safe performance over lifetimes of up to 100,000 h.

Available in a wide range of voltage and capacitance values, the capacitors exhibit low DCL, ESR and ESL, high current handling capabilities and good high-frequency performance and capacitance retention with frequency. They are suitable for use in AC/DC power converters, renewable energy inverters, rolling stock and oil drilling applications.
