The Type 330 is the ultra-long-life version of the Type 300 capacitor. With an astonishing, 50,000-hour expected life operating continuously at full load and 65 ºC the 330 is the choice for power supply outputs and UPS battery stiffening. The exceptionally low ESRs enable high ripple-current capability.
The Type 330 capacitor family is the ultra‑long‑life version of the Type 300 series, offering an expected 50,000‑hour life at full load and 65 °C. Its low ESR enables ripple currents up to 16 A, making it suitable for switching power supplies and UPS battery stiffening. The series includes three‑lead (330, 330R) and two‑lead (331, 331R) versions, with epoxy‑sealed and bare‑can options.
Technical data sheets provide detailed specifications such as operating temperature from –55 °C to +105 °C, rated voltages from 6.3 V to 250 Vdc, capacitance values from 270 µF to 33 000 µF, ESR as low as 6 mΩ, and an expected life of over 20 years at 45 °C. Dimensional drawings and performance curves are included for each voltage and case size.
