The capacitors are rated 0.01µF to 0.47µF, with voltages spanning 250 to 2000V, and operating temperatures from -40 to 105C. They are designed for high frequency and high pulse rise-time circuits, high voltage power supplies, SMPS (switch mode power supplies), power converters, snubbers, and electronic lighting ballasts, such as compact florescent lamps and LEDs. Unlike aluminum electrolytic capacitors, they do not have a catastrophic failure mode. Instead they experience a parametric loss of capacitance of approximately2 % from their initial value, eliminating the risk of short circuit and enabling continued functionality.
