The Cornell Dubilier Type 330 capacitor is an ultra-long-life radial capacitor specifically engineered for demanding applications such as power supply outputs and UPS battery stiffening. Its exceptional design provides an astonishing 50,000-hour expected life when operating continuously at full load and 65°C. The low Equivalent Series Resistance (ESR) enables high ripple-current capability, often allowing a single Type 330 capacitor to replace three or four smaller capacitors in switching power supplies. The three-lead design provides rugged, reverse-proof mounting, while the available Types 331 and 331R offer two-lead alternatives. This capacitor is a reliable and efficient solution for a wide range of industrial and commercial applications.
