LNU2H472MSEH

The LNU2H472MSEH is an aluminum electrolytic capacitor in Nichicon's LNU series designed for screw‑terminal mounting. It provides 4.7 mF capacitance at a 500 V DC rating and is built for demanding industrial power applications.

Engineered for inverter and motor-drive environments, this capacitor supports high‑frequency regenerative voltages, high‑speed charge/discharge loading and continuous operation at elevated temperatures, making it suitable for industrial power supplies and inverter circuitry.

Key Features

• Capacitance & Voltage: 4.7 mF nominal capacitance with a 500 V DC rated voltage and ±20% tolerance.
• High‑Temperature Endurance: Specified operating range from −40°C to +105°C and a rated load life of 5000 hours at 105°C with applied ripple current.
• High Ripple Current Handling: Rated ripple current of 13.9 A at 120 Hz and 19.46 A at 10 kHz, supporting high‑power and high‑frequency applications.
• Charge–Discharge Durability: Designed to cope with high‑speed charge/discharge loading; datasheet endurance testing includes long‑term charge/discharge cycles (50 million cycles, 3 Hz, per datasheet conditions).
• Package & Mounting: Radial can with screw terminals for robust electrical and mechanical connections; brackets supplied separately as noted in the datasheet.
• Low‑Temperature Stability: Maintains impedance characteristics at low temperature (Z(−40°C)/Z(+20°C) ≤ 8 for rated voltages 400–525 V).
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies: Bulk energy storage and smoothing for inverter circuitry in industrial power supplies.
• AC Servomotor Drives: Supports high‑frequency regenerative voltage handling in servomotor control systems.
• General Inverter Systems: High voltage and ripple capability for general inverter and motor‑drive designs.
• High‑Speed Charge/Discharge Circuits: Suitable where repeated fast charge/discharge cycles are required by the application.

Unique Advantages

• High‑Voltage Capability: 500 V rating (part of a range up to DC525 V) enables designs handling elevated DC bus voltages without series stacking.
• Long Life at Elevated Temperature: 5000 hours load life at 105°C under rated ripple current provides predictable endurance in hot industrial environments.
• High Ripple Current Performance: Robust ripple ratings at both low and high frequencies reduce heating and extend service life in high‑power circuits.
• Robust Mechanical Termination: Screw terminals deliver secure, low‑impedance connections for high‑current and vibration‑prone installations.
• Compact High‑Voltage Form Factor: LNU series offers a smaller footprint compared with larger high‑voltage options, useful where space and voltage capability must be balanced.
• RoHS Compliant: Meets current RoHS requirements for environmentally restricted substance compliance.
