LNU2G822MSEJBN

The LNU2G822MSEJBN is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNU series designed for industrial power applications. It provides a compact, high‑voltage energy storage solution optimized for inverter circuitry, regenerative systems and other high‑frequency charge/discharge loads.

As a polarized radial can with screw terminals, this part combines a 400 V DC rating and 8.2 mF capacitance with high ripple handling and a 105°C operating rating to support demanding industrial power designs.

Key Features

• Electrical Capacity — 8.2 mF (8200 μF) nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C), suitable for bulk energy storage and smoothing in power stages.
• Voltage Rating — Part rated at 400 V DC; the LNU series covers rated voltages up to DC 525 V to address a range of high‑voltage power designs.
• High Ripple and Frequency Performance — Ripple current capability of 23.1 A at 120 Hz and 32.34 A at 10 kHz, enabling use in both low‑ and high‑frequency power circuits.
• Thermal and Lifetime — Designed for continuous operation from −40°C to +105°C with a load life of 5000 hours at 105°C under rated ripple and DC bias conditions.
• Mechanical and Mounting — Radial can package with screw terminals for secure, low‑resistance connections in industrial assemblies and serviceable installations.
• Reliability and Safety Tests — Series specifications include insulation resistance >100 MΩ at DC 500 V between terminal and bracket and voltage proof testing (AC 2500 V for 1 minute) as part of quality control criteria.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing for inverter‑type supplies and high‑voltage DC link circuits.
• Motor Drives and Regenerative Systems: High‑frequency regenerative voltage handling for AC servomotors and general inverter regenerative paths.
• High‑Speed Charge/Discharge Circuits: Energy buffering for circuits that require rapid charge/discharge cycles under load.
• General Inverter Systems: Filtering and energy storage in inverter stages where compact, high‑voltage capacitors are required.

Unique Advantages

• High‑Voltage Capability: 400 V DC rating with the LNU family spanning up to 525 V, providing flexibility across high‑voltage designs.
• Robust Ripple Handling: High ripple current ratings at both 120 Hz and 10 kHz reduce temperature rise and extend service life in power circuits.
• 105°C Endurance: Rated to operate up to 105°C with a specified 5000‑hour load life under rated ripple and DC bias, supporting long‑term reliability in harsh environments.
• Screw Terminal Convenience: Screw‑terminal mounting enables secure electrical connections and simplifies replacement or maintenance in industrial systems.
• Compact, High‑Energy Density: Smaller footprint compared with larger high‑voltage cans in the same family, allowing space‑efficient design without sacrificing voltage handling.
• Charge‑Discharge Endurance: Series endurance testing includes high‑cycle charge/discharge verification to ensure consistent performance under repeated cycling.
