The 381LL and 383LL series of long-life snap-in aluminum electrolytic capacitors from Cornell Dubilier are in stock at New Yorker Electronics.

The electrolytic capacitors, designated with an expected life of 8,000 hours at full-rated conditions, demonstrate superb stability in capacitance and DC leakage current over time on test.

The snap-in series is targeted for use in critical applications where reliability and the life span of the capacitor banks are essential to system reliability.

Capacitance values range from 740µF to 100,000µF at working voltages of 16 to 250WVDC with ripple current ratings up to 10 amps @ 105°C.

The snap-in series is available in a two-, four- and five-pin version.

The two-pin 381LL ranges in diameter from 25 to 40mm diameter.

The four-pin 383LL is available in either 35 or 40mm diameter options and the five-pin 383LL has a 40mm diameter.

They use CDE’s most advanced electrolyte system to deliver reliable performance and stability over the life of the capacitor.

The temperature range of the components is -55 degrees C to + 105 degrees C and the rated voltage range is 16Vdc to 25Vdc.

Capacitor tolerance is +/- 20%.

Leakage current is ≤3 √CV μA, 4 mA max, 5 minutes.

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

They offer reduced leakage current over operating life, stable ESR and dissipation factor over operating life and are RoHS Compliant.

Applications include Switch-Mode Power Supplies, uninterruptible power supplies (UPS) and solar/high-power Inverters
