LNC2G822MSEH

The LNC2G822MSEH is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNC series, offering 8.2 mF (8200 µF) capacitance at a 400 V rating. Designed for industrial power electronics, it targets inverter circuitry and AC servomotor regenerative circuits where compact size, high ripple tolerance and robust endurance are required.

Key value comes from a smaller package with higher ripple-current capability compared with prior LNC series members, suitability for high‑frequency charge–discharge conditions, and a 5000‑hour load life at 85°C under rated ripple current.

Key Features

• Capacitance & Voltage — 8.2 mF (8200 µF) rated at 400 V with ±20% tolerance (120 Hz, 20°C).
• Screw Terminal Mounting — Radial can with screw terminals for secure power connections in high-current industrial layouts.
• High Ripple Current Handling — Rated ripple currents of 26.1 A at 120 Hz and 36.54 A at 100 kHz for demanding AC and high‑frequency applications.
• Endurance — Load life specified as 5000 hours at 85°C when DC bias plus rated ripple current is applied; also designed to withstand 50 million charge–discharge cycles at room temperature under defined test conditions.
• Wide Temperature Range — Operational from −40°C to +85°C to support industrial ambient conditions.
• Leakage and Insulation Characteristics — Leakage current specified (after 5 minutes at 20°C) as not more than 3√(V) μA or 5 mA, whichever is smaller; insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V for 1 minute between terminal and bracket.
• Compact Form Factor — Smaller-sized design within the LNC family with physical dimensions L: 14.5 × D: 7.62 cm for space-conscious power modules.
• Polarized Design — Polarized electrolytic construction for DC link and energy storage use.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — DC link and filtering in inverter power supplies where high ripple current and endurance are required.
• AC Servo Drives — Conditioning and regenerative voltage handling in AC servomotor systems, including high‑frequency regenerative circuits.
• General Inverters — Energy storage and smoothing for motor control and conversion stages subject to rapid charge–discharge cycles.

Unique Advantages

• Higher ripple capability in a smaller package — Delivers elevated ripple currents while reducing board footprint compared with earlier LNC family variants.
• Long rated service life at elevated temperature — 5000 hours at 85°C under rated ripple conditions provides predictable endurance for industrial applications.
• High‑frequency performance — Specified ripple current at 100 kHz supports designs with fast switching and regenerative voltage events.
• Robust electrical safety margins — Insulation resistance and voltage‑proof ratings between terminal and bracket help ensure dielectric reliability in high-voltage assemblies.
• Designed for repeated charge–discharge — Endurance validated for tens of millions of cycles under defined test conditions for demanding motor control and power-conversion use cases.
