LNU2H222MSEH

The LNU2H222MSEH is a high-voltage aluminum electrolytic capacitor in a screw-terminal radial can designed for industrial power applications. It delivers 2200 µF at a 500 V DC rating with a compact φ76.2 × 95 mm package and screw terminals for robust, high-current connections.

Engineered for inverter and regenerative power circuitry, the LNU2H222MSEH combines high ripple-current capability and 5000-hour endurance at 105°C to support demanding charge–discharge and high-frequency loading conditions.

Key Features

• Capacitance & Tolerance — 2200 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C), providing energy storage for power conversion and smoothing.
• High Voltage Rating — Rated voltage 500 V DC to support high-voltage industrial supplies and inverter bus applications.
• Ripple Current Performance — Low-frequency ripple current of 8.5 A (120 Hz) and high-frequency ripple current of 11.9 A (10 kHz) to handle both mains-frequency and high-frequency switching loads.
• Endurance at Elevated Temperature — 5000 hours life at 105°C under rated ripple conditions, suitable for sustained high-temperature operation.
• Operating Temperature Range — –40°C to +105°C for broad industrial temperature compatibility.
• Screw Terminal Mounting — Radial can with screw terminals (M5 nominal bolt) for secure, low-impedance connections in high-current assemblies.
• Leakage Current — Specified leakage current of 3140 µA (measured conditions per part data), with datasheet guidance on post-application limits.
• Compact High-Voltage Form Factor — φ76.2 × 95 mm size delivers high DC voltage capability in a relatively small package for the LNU family.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Industrial Inverters — Bulk and DC-link smoothing for inverter power supplies where 500 V rating and high ripple capability are required.
• AC Servo Drives — Support for regenerative voltage and high-speed charge–discharge cycles in motor-control systems.
• Power Conversion — Energy storage and filtering in high-voltage power supplies and DC–DC converter stages.

Unique Advantages

• High-voltage capability in a compact can — 500 V rating with a φ76.2 × 95 mm envelope allows designers to implement high-voltage bus capacitance without excessive space penalty.
• Dual-frequency ripple handling — Rated ripple current figures at 120 Hz and 10 kHz support both low-frequency smoothing and high-frequency switching environments.
• Robust high-temperature endurance — 5000-hour life at 105°C under rated ripple ensures longevity in thermally challenging installations.
• Secure high-current connections — Screw terminal mounting and M5 bolt provision simplify assembly and provide reliable low-impedance terminals for heavy current paths.
• Designed for rapid charge–discharge — Specified to cope with high-speed charge–discharge loads typical in regenerative and inverter applications.
• Compliance and supply assurance — RoHS compliance aligns with environmental directives for industrial component sourcing.
