Aluminum electrolytic snap-in capacitors provide long-life

23-01-2020 | Cornell Dubilier | Passives

Cornell Dubilier Electronics has introduced its 381LL series of long-life snap-in aluminium electrolytic capacitors. The series, designated with an anticipated life of 8,000 hours at full-rated conditions, exhibits superb stability in capacitance and DC leakage current over time on test. The snap-in series is aimed at critical applications where long life and reliability are paramount.


Capacitance values extend from 740µF to 100,000µF at working voltages of 16 to 250WVDC with ripple current ratings up to 10A @ 105C. The snap-in series is offered in two-pin configurations in the smaller diameters with four and five-pin options in the larger diameters.


General applications include any circuit demanding high capacitance with low ESR, high ripple current and long life. This includes SMPS, UPS systems, solar and other high-power inverters.
