LNU2G332MSEHBN

The LNU2G332MSEHBN is a 3300 µF, 400 V aluminum electrolytic capacitor in a screw-terminal radial can designed for high-voltage industrial power electronics. Built for demanding inverter and motor-drive environments, it delivers high ripple-handling capability and endurance at elevated temperatures.

As part of Nichicon’s LNU series, this screw-terminal, high-voltage capacitor is optimized for inverter circuitry, high-frequency regenerative voltage on AC servomotors, and other industrial power-supply applications where high-voltage performance, secure connections, and long life at 105°C are required.

Key Features

• Capacitance & Voltage: 3300 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance (120 Hz, 20°C), providing bulk energy storage for high-voltage circuits.
• High-temperature Endurance: Rated for operation from −40°C to +105°C with a load life of 5000 hours at 105°C under rated ripple conditions for stable long-term performance.
• High ripple-current capability: Designed to handle ripple current of 13.1 A at 120 Hz and 18.34 A at 10 kHz, supporting high-frequency charge–discharge and regenerative duty.
• Screw-terminal radial package: Robust screw terminal connections on a radial can package (radial, can - screw terminals) for secure, low-impedance power connections in industrial assemblies.
• Smaller-sized high-voltage option: LNU series offers high-voltage performance in a smaller footprint compared with the LNT series, facilitating tighter layouts.
• Polarized electrolytic design: Polar construction suited for DC bulk filtering and energy buffering in power converters and inverter systems.
• RoHS compliance: Compliant to the RoHS directive (2011/65/EU,(EU)2015/863), meeting standard environmental restrictions.

Typical Applications

• Industrial inverter power supplies: Bulk energy storage and filtering for inverter front-ends and DC-link circuits in industrial drives.
• AC servomotor regenerative circuits: Handles high-frequency regenerative voltage and rapid charge–discharge cycles encountered in servo drive systems.
• General inverter systems: Supporting DC-link smoothing and ripple handling in general-purpose inverter and motor-control designs.

Unique Advantages

• High-voltage capability: 400 V rated voltage (part of a series rated up to DC525 V) allows use in elevated-voltage DC-link applications.
• Compact high-voltage footprint: Smaller-sized construction compared to LNT-series parts enables denser power-electronics layouts without sacrificing voltage rating.
• Designed for high-frequency duty: Rated ripple currents up to 18.34 A at 10 kHz support high-speed charge–discharge and regenerative duties.
• Long-term thermal reliability: 5000 hours load life at 105°C demonstrates sustained performance under elevated-temperature ripple loading.
• Secure screw-terminal connections: Screw-terminal mounting and radial can packaging provide mechanically robust, low-impedance connections for industrial assemblies.
• Environmentally compliant: RoHS status ensures the part meets current restricted-substances requirements.
