LNU2G472MTEG

The LNU2G472MTEG is a Nichicon LNU series aluminum electrolytic capacitor in a screw-terminal (stud bolt) can package. It provides 4700 µF capacitance at a 400 V DC rating with a compact φ63.5 × 120 mm form factor designed for power applications that require high-voltage energy storage and robust terminal connections.

Designed for industrial power electronics, the LNU2G472MTEG suits inverter circuitry and high-frequency regenerative environments where high ripple handling, extended endurance at elevated temperature, and secure mechanical mounting are required.

Key Features

• Capacitance & Voltage — 4700 µF (4.7 mF) rated at 400 V DC with ±20% tolerance (120 Hz, 20°C), providing bulk energy storage for high-voltage power rails.
• High ripple handling — Low-frequency ripple current 16.1 A (120 Hz) and high-frequency ripple current 22.54 A (10 kHz), enabling support for both mains-frequency smoothing and high-speed charge/discharge cycles.
• Electrical loss and leakage — Specified tanδ of 0.2 and a measured leakage current of 4110 µA, useful for estimating dissipation and standby losses in system designs.
• Endurance at elevated temperature — 5000 hours load life at 105°C under rated ripple conditions, supporting long-term operation in hot industrial environments.
• Wide operating temperature — Rated for −40°C to +105°C to cover a broad range of environmental conditions.
• Rugged mechanical package — Radial can with screw terminals / stud bolt mount (φ63.5 size uses M5 nominal bolt per series drawing) for secure, low-inductance connections in power assemblies.
• Series capability — Part of the LNU family, which supports rated voltages in the 400–525 V range and is optimized for high-voltage, smaller-sized installations.
• RoHS compliant — Meets RoHS requirements for restricted substances as noted in the product data.

Typical Applications

• Industrial power supplies — Bulk smoothing and energy storage for inverter front-ends and high-voltage DC rails in industrial power supplies.
• Motor drive and servo inverters — Energy buffering and high-frequency ripple handling for AC servomotor drives and general inverter circuits.
• Regenerative systems — Handles high-speed charge–discharge cycles and high-frequency regenerative voltages encountered in regenerative braking or energy-recovery circuits.

Unique Advantages

• High-voltage, compact footprint — 400 V rating in a φ63.5 × 120 mm can provides high-voltage capacitance while conserving board/panel space compared with larger diameter options.
• High ripple capability across frequencies — Specified ripple currents at both 120 Hz and 10 kHz allow a single component to address mains-frequency smoothing and high-frequency switching noise.
• Long endurance at 105°C — 5000-hour rated life under rated ripple ensures predictable aging and maintenance planning for continuous industrial operation.
• Secure screw-terminal mounting — Stud bolt (M5 for φ63.5) terminations provide mechanically robust, low-inductance connections suitable for high-current power assemblies.
• Quantified electrical characteristics — Specified tanδ and leakage current values enable accurate thermal and leakage budgeting in system-level designs.
• RoHS compliance — Aligned with environmental substance regulations for easier integration into compliant manufacturing processes.
