LNU2H222MTEH

The LNU2H222MTEH is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNU series designed for high‑voltage industrial power applications. As a stud/bolt mount radial can with screw terminals, it provides 2.2 mF capacitance at a 500 V DC rating and is optimized for inverter and regenerative circuits where high ripple and rapid charge‑discharge loading occur.

Engineered for demanding environments, the capacitor is specified for operation from −40°C to +105°C and offers a long load life with verified endurance under rated ripple current at elevated temperature.

Key Features

• Electrical Performance — 2.2 mF nominal capacitance with a rated voltage of 500 V DC and capacitance tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High Voltage Capability — Part of a series rated up to DC 525 V (this part at 500 V), suitable for high‑voltage inverter and power supply rails.
• High Ripple and HF Performance — Rated ripple current of 8.5 A at 120 Hz and 11.9 A at 10 kHz to support high‑frequency regenerative and switching loads.
• Thermal and Endurance Rating — Designed for continuous operation up to 105°C with a load life of 5000 hours under rated ripple current and DC bias at 105°C.
• Robust Insulation and Voltage Proof — Insulation resistance greater than 100 MΩ at DC 500 V (terminal to bracket) and voltage proof tested at AC 2500 V for 1 minute (terminal to bracket).
• Mounting and Package — Stud bolt (M5) mount with screw terminals in a radial can package for secure mechanical and electrical connection in industrial assemblies.
• Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Bulk and smoothing capacitance on DC bus rails for general inverter power supplies, improving stability under switching loads.
• AC Servomotor Drives — Energy buffering and regenerative voltage handling in high‑frequency regenerative circuits for servo and motion control systems.
• High‑Speed Charge/Discharge Circuits — Applications requiring rapid charge and discharge cycles benefit from the series’ endurance to repeated charge‑discharge behavior.
• Industrial Power Supplies — DC link and filtering in industrial power supplies where elevated temperature and sustained ripple current are encountered.

Unique Advantages

• High‑voltage capability: 500 V rating (series up to 525 V) enables use on elevated DC bus voltages common in inverter and regenerative systems.
• Designed for elevated temperature operation: Specified for −40°C to +105°C with a 5000‑hour endurance at 105°C under rated ripple current, supporting reliable long‑term operation in harsh environments.
• High ripple current at multiple frequencies: Measured ripple currents of 8.5 A (120 Hz) and 11.9 A (10 kHz) provide clear, verifiable performance for both mains‑frequency and high‑frequency switching applications.
• Mechanical reliability: Stud bolt mount with screw terminals and radial can packaging offers secure mounting and robust electrical connections for industrial assemblies.
• Verified electrical integrity: Insulation resistance >100 MΩ (DC 500 V) and AC 2500 V, 1‑minute voltage proof between terminal and bracket reduce risk of breakdown in high‑voltage environments.
• Regulatory compliance: RoHS conformity ensures material compliance for regulatory and procurement requirements.
