Rated for 1.5–3 kV with capacitance spanning 58–1,110 µF, FFLI Series Capacitors combine dry, metallized polypropylene film and no-free-oil solution in cylindrical aluminum case filled with self-extinguishing polyurethane resin. Composition equips series with self-healing technology, which prevents potential explosions resulting from avalanche effect, enables benign failure mode consisting exclusively of capacitance losses, and ensures safe performance over 100,000-hour lifetime.
