LNUN7562MTEJ

The LNUN7562MTEJ is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNU series, delivering 5600 µF at a rated DC voltage of 525 V. It is designed for high-voltage industrial power applications where a compact, high-capacitance, stud-mounted solution is required.

Suited for inverter circuitry, high-frequency regenerative voltage circuits for AC servomotors and general inverters, this part combines high-voltage capability with a smaller-sized package and features optimized for high-speed charge–discharge loading and prolonged operation at elevated temperatures.

Key Features

• High Voltage Handling — Rated voltage up to DC 525 V for industrial high-voltage power systems.
• Large Capacitance — 5600 µF (5.6 mF) nominal capacitance with ±20% tolerance (120 Hz, 20°C) for energy buffering and smoothing.
• Wide Temperature Range & Long Life — Operates from –40°C to +105°C with a rated load life of 5000 hours at 105°C under rated ripple current conditions.
• High Ripple Current Capability — 17.5 A at 120 Hz and 24.5 A at 10 kHz to support high-frequency inverter and regenerative loads.
• Stud Bolt Mount / Screw Terminals — Radial can package with screw terminals and stud/bolt mounting for secure, low-inductance power connections.
• Charge–Discharge Endurance — Designed to withstand high-speed charge–discharge loading; series specifications include endurance for repeated cycles.
• Leakage and Insulation Characteristics — Leakage current specification and an insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket, with voltage proof of AC 2500 V for 1 minute between terminal and bracket.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact High-Voltage Form Factor — Smaller-sized construction within the LNU series while maintaining high-voltage performance; physical size listed as L: 15.5 × D: 9 cm.
