LNU2W562MSEJBN

The LNU2W562MSEJBN is a screw-terminal aluminum electrolytic capacitor with 5600 µF capacitance and a 450 V DC rating, designed for demanding industrial power applications. It is built for high-temperature operation up to 105°C and supports heavy ripple and high-frequency regenerative voltages common in inverter and motor-drive systems.

Part of Nichicon’s LNU series, this capacitor delivers high-voltage capability in a reduced footprint compared with legacy options, with a rated load life under ripple conditions of 5000 hours at 105°C and RoHS compliance.

Key Features

• Capacitance & Voltage — 5600 µF nominal capacitance with a rated voltage of 450 V (series rated voltage range up to DC 525 V).
• High Temperature Endurance — Rated for operation from −40 °C to +105 °C with a specified load life of 5000 hours at 105 °C under rated ripple conditions.
• High Ripple and High-Frequency Performance — Supports 19.6 A ripple at 120 Hz and 27.44 A at 10 kHz, suitable for high-frequency regenerative and inverter environments.
• Screw Terminal Package — Radial can with screw terminals for secure, low-impedance connections in power assemblies.
• Charge–Discharge Durability — Designed to cope with high-speed charge–discharge loading; series endurance testing includes 50 million charge–discharge cycles (ΔV = rated voltage ±0.3, 3 Hz).
• Polarized, General-Purpose Power — Polarized aluminum electrolytic intended for general industrial power supply and inverter circuitry applications.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Energy storage and smoothing in inverter DC-link stages where high voltage and ripple capability are required.
• AC Servomotor Drives — Handling high-frequency regenerative voltages and rapid charge–discharge cycles in motor control systems.
