LNU2G103MSEJBB

The LNU2G103MSEJBB is a screw‑terminal aluminum electrolytic capacitor in the Nichicon LNU series, specified at 10 mF (10000 µF) and 400 V with a −40 °C to 105 °C operating range. It is designed for industrial power electronics where high voltage, high ripple handling and robust connections are required.

Suited for inverter circuitry, AC servomotor drives and high‑frequency regenerative voltage applications, the LNU2G103MSEJBB delivers long load life and high ripple capability in a smaller package footprint compared with the LNT series. It is rated for 5000 hours of endurance at 105 °C under rated ripple conditions and is RoHS compliant.
