LNU2W822MSEHBB

The LNU2W822MSEHBB is a high‑voltage, screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNU series. It is designed for industrial power electronics where compact high‑voltage energy storage, robust ripple handling and reliable long‑term operation at elevated temperatures are required.

Typical use cases include industrial power supplies and inverter circuitry, including high‑frequency regenerative voltage conditions for AC servomotors and general inverters. The part combines a 450 V rating with a compact radial can screw‑terminal package and a 105°C rated operating temperature.

Key Features

• Electrical capacity — 8.2 mF nominal capacitance with ±20% tolerance (at 120 Hz, 20°C), polarized for DC applications.
• High voltage rating — Rated voltage: 450 V DC; the LNU series supports voltages up to DC525 V (series specification).
• High‑temperature endurance — Designed for operation to 105°C with a rated load life of 5000 hours under applied ripple current at 105°C.
• Ripple and high‑frequency performance — Ripple current capability of 25.7 A at 120 Hz and 35.98 A at 10 kHz, and specified to cope with high‑speed charge‑discharge cycles and high‑frequency regenerative voltages.
• Mounting and package — Screw terminal mounting in a radial can package for secure, low‑impedance power connections.
• Environmental and safety characteristics — Operating temperature range –40°C to +105°C; RoHS‑compliant (2011/65/EU, (EU)2015/863).
• Leakage and electrical stability — Leakage current after 5 minutes’ application of rated voltage is specified as not more than 3√CV (μA) or 5 mA, whichever is smaller (at 20°C); insulation resistance and voltage‑proof tests are specified between terminal and bracket.
• Dimensions — Body length and diameter: L: 19.5 × D: 7.62 cm (radial can with screw terminals).

Typical Applications

• Industrial inverter power supplies — Energy buffering and DC link stabilization in inverter front‑ends where high voltage and high ripple capability are required.
• AC servomotor regenerative circuits — Handling high‑frequency regenerative voltages and rapid charge‑discharge cycles common in servo drives.
• General industrial power electronics — Bulk energy storage and ripple smoothing for industrial converters and power modules operating up to 105°C.

Unique Advantages

• High‑voltage capability: 450 V rated (series up to DC525 V), enabling use in higher‑voltage DC link applications without additional series stacking.
• Compact high‑voltage form factor: Smaller sized than the LNT series while delivering comparable high‑voltage performance, helping reduce board and chassis space.
• Robust thermal life: 5000 hours load life at 105°C under rated ripple current, providing predictable longevity in hot industrial environments.
• High ripple and HF performance: Specified ripple current at both 120 Hz and 10 kHz and designed for high‑speed charge‑discharge, suitable for high‑frequency inverter and regenerative scenarios.
• Screw terminal package: Provides secure, low‑resistance connections for high current flow and reliable mechanical retention in industrial assemblies.
• RoHS compliance: Meets applicable RoHS directives, supporting regulatory requirements for lead‑restricted assemblies.
