8,000 Hour, 105°C Aluminium Electrolytic Snap-in Capacitors

Cornell Dubilier introduces the 381LL series of long-life snap-in aluminium electrolytic capacitors.

Cornell Dubilier 381LL Series

The series, designated with an expected life of 8,000 hours at full-rated conditions, demonstrates superb stability in capacitance and DC leakage current over time on test. The snap-in series is targeted for use in critical applications where long life and reliability are paramount.

  • 8,000 hour life at full rated conditions 
  • Stable capacitance over operating life 
  • Reduced leakage current over operating life 
  • Stable ESR and dissipation factor over operating life
  • RoHS Compliant

Capacitance values range from 740µF to 100,000µF at working voltages of 16 to 250 WVDC with ripple current ratings up to 10 Amps @ 105 °C. The snap-in series is available in two pin configurations in the smaller diameters with 4 and 5 pin options in the larger diameters.


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