LNU2G562MSEG

The LNU2G562MSEG is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNU series, designed for high-voltage industrial power applications. It combines a 5.6 mF capacitance with a 400 V rated voltage and a compact radial can with screw terminals, targeting inverter circuitry, AC servomotor drives and other high-frequency regenerative systems.

Engineered for reliability under harsh conditions, this capacitor supports operation from –40°C to 105°C and a rated load life of 5000 hours at 105°C with ripple current applied, making it suited to designs that require sustained high ripple handling and rapid charge–discharge performance.

Key Features

• Capacitance & Voltage — 5.6 mF capacitance with a 400 V rated voltage for bulk energy storage and smoothing in high-voltage circuits.
• High-temperature endurance — Specified to operate from –40°C to 105°C with a load life of 5000 hours at 105°C under rated ripple current.
• High ripple and high-frequency performance — Ripple current ratings of 17.7 A at 120 Hz and 24.78 A at 10 kHz support heavy ripple and high-frequency regenerative voltages.
• Screw terminal radial can — Robust screw-terminal mounting and radial can package for secure electrical and mechanical connections in industrial assemblies.
• Endurance and charge–discharge cycling — Datasheet specifies endurance to 50 million charge–discharge cycles (3 Hz) under the defined test conditions.
• Leakage and safety characteristics — Leakage current specified as not more than 3√CV (μA) or 5 mA (whichever is smaller) after 5 minutes at 20°C; insulation resistance >100 MΩ at DC 500 V and AC 2500 V/1 minute voltage proof between terminal and bracket.
• Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies (inverter circuitry) — Provides bulk energy storage and smoothing for inverter DC links and high-voltage industrial power rails.
• AC servomotor drives — Handles high-frequency regenerative voltage and rapid charge–discharge cycles encountered in servo and motion-control systems.
• General inverter systems — Supports high ripple current and high-speed switching environments in general-purpose inverter and motor-control designs.

Unique Advantages

• High-voltage capability — 400 V rating (series rated up to DC525 V) allows use in many high-voltage DC-link applications.
• Designed for heavy ripple — High ripple current ratings at both low and high frequencies reduce heating and extend service life under demanding load conditions.
• Long high-temperature life — 5000 hours at 105°C under rated ripple current gives predictable life performance for continuous industrial operation.
• Robust screw-terminal mounting — Screw terminals provide secure electrical connection and ease of installation in power assemblies.
• Charge–discharge endurance — Specified endurance to 50 million cycles (3 Hz) supports applications with frequent high-speed switching and regenerative events.
• Regulatory compliance — RoHS compliance supports environmentally conscious designs and regulatory requirements.
