LNU2H222MSEHBB

The LNU2H222MSEHBB from Nichicon is a screw‑terminal, high‑voltage aluminum electrolytic capacitor in the LNU series designed for industrial power applications. It provides 2.2 mF (2200 µF) capacitance at a 500 V rating with polarized screw‑terminal mounting in a compact radial can package.

Engineered for inverter circuitry, high‑frequency regenerative voltages and other industrial power supplies, this capacitor combines high voltage capability, high ripple handling and 105°C endurance for robust performance in demanding environments.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) nominal capacitance with a 500 V rated DC working voltage; capacitance tolerance ±20% (120 Hz, 20°C).
• High‑Temperature Endurance — Rated for operation from –40°C to +105°C with a specified load life of 5000 hours at 105°C under rated ripple conditions.
• Ripple Current Performance — Handles 8.5 A at 120 Hz and 11.9 A at 10 kHz, suitable for both low‑ and high‑frequency ripple environments.
• Robust Mechanical Package — Radial can with screw terminals for secure bolted connections; terminals use M5 nominal bolt size based on series drawing information.
• High‑Voltage Series Characteristics — Part of the LNU series with rated voltage range up to DC 525 V and designed to cope with high‑speed charge/discharge and high‑frequency regenerative voltages.
• Safety & Leakage — Leakage current specified as not more than 3√CV (μA) or 5 mA after 5 minutes at 20°C; insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU,(EU)2015/863).
• Compact Footprint — Smaller sized than the LNT series while maintaining high voltage and performance; part dimensions L: 9.5 cm × D: 7.62 cm for space‑conscious designs.

Typical Applications

• Industrial Inverter Power Supplies — Bulk energy storage and smoothing for inverter front‑ends where high DC voltage and long life at 105°C are required.
• AC Servomotor Regenerative Circuits — Handles high‑frequency regenerative voltage and rapid charge/discharge cycles common in servo drive DC buses.
• General Inverter Systems — Energy buffering, ripple suppression and charge/discharge cycling in general industrial inverter topologies.

Unique Advantages

• High Voltage Capability: 500 V rating (series up to DC 525 V) enables use in high‑voltage DC bus applications without stepping up component count.
• Designed for High‑Frequency Loads: Specified ripple currents at both 120 Hz and 10 kHz make the capacitor suitable for mixed‑frequency environments and regenerative loads.
• Extended High‑Temperature Life: 5000 hours at 105°C with specified endurance characteristics provides predictable long‑term performance under heavy thermal stress.
• Screw‑Terminal Reliability: Radial can with screw terminals and M5 bolt nominal size supports secure mechanical and electrical connections in rugged installations.
• Compact Size for High Voltage: Smaller footprint than comparable LNT series parts while retaining high voltage and ripple handling capability, aiding compact power module designs.
• Specification‑Driven Selection: Clear, measurable specs for leakage, tan δ, impedance ratio at low temperature and endurance help engineers validate designs against application requirements.
