LNC2W332MSEH

The LNC2W332MSEH is a screw-terminal, aluminum electrolytic capacitor from Nichicon’s LNC series, rated 3300 µF at 450 V and designed for industrial power electronics. It delivers high ripple-current capability in a smaller-sized package and is optimized for inverter circuitry and regenerative high-frequency applications.

Engineered for rugged service, the part offers a wide operating range (–40 °C to +85 °C), a load life of 5000 hours at 85 °C under rated ripple, and RoHS compliance—making it suitable for industrial power supplies, inverters and servo regenerative circuits.

Key Features

• Electrical Rating: 3.3 mF (3300 µF) capacitance at 450 V nominal with ±20% tolerance.
• High ripple-current capability: 15.5 A at 120 Hz and 21.7 A at 100 kHz to support high-frequency and heavy ripple loading.
• Load life and endurance: Rated for 5000 hours at 85 °C under rated ripple current; additionally specified for 50 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz) at room temperature.
• Temperature and stability: Operating temperature range –40 °C to +85 °C with impedance stability specified down to –40 °C.
• Package and mounting: Screw-terminal radial can with secure screw-terminals for robust electrical and mechanical connection; compact physical size L: 8.5 × D: 7.62 cm.
• Leakage and safety characteristics: Leakage current after 5 minutes is limited to 3√(V) µA or 5 mA (whichever is smaller) as specified.
• Compliance: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies: Bulk and smoothing capacitance for inverter front-ends and DC-link circuits where high ripple handling and long life are required.
• Inverter circuitry: Energy storage and ripple suppression in general inverter designs and motor drive power stages.
• AC servomotor regenerative circuits: Handling high-frequency regenerative voltages and rapid charge–discharge cycles in servo and motion-control systems.
