LNU2H682MTEJ

The LNU2H682MTEJ from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNU series, engineered for high‑voltage industrial power applications. It delivers 6800 µF at a 500 V rating with polarized construction and a compact screw‑terminal can package suitable for stud/bolt mounting.

Designed for inverter and regenerative circuits, this capacitor targets industrial power supplies, AC servomotor regenerative systems and high‑frequency inverter environments where high voltage, high ripple capability and extended high‑temperature life are required.

Key Features

• Electrical performance — 6800 µF capacitance with a 500 V rated voltage (polarized), tolerance ±20% (120 Hz, 20°C).
• High ripple capability — Rated ripple current of 18.5 A at 120 Hz and 25.9 A at 10 kHz to support heavy AC ripple and high‑frequency regenerative voltages.
• Thermal and lifetime rating — Operates from −40°C to +105°C with a load life of 5000 hours at 105°C under rated ripple current and DC bias.
• Robust construction and mounting — Screw terminal (stud/bolt mount) radial can package for secure high‑current connections and mechanical stability in industrial assemblies.
• Size and packaging — Smaller high‑voltage form factor within the LNU series; physical dimensions L: 16.5 × D: 9 cm and maximum seated height 6.496 inch for compact installations.
• Leakage current specification — After 5 minutes’ application of rated voltage, leakage is limited to 3√(C·V) µA or 5 mA, whichever is smaller (at 20°C).
• Regulatory compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies — Bulk energy storage and smoothing for inverter power stages and DC link circuits.
• Inverter and motor drives — Supports high‑frequency regenerative voltage and energy exchange in AC servomotor and general inverter systems.
• High‑speed charge/discharge systems — Suited for circuits that require rapid charge/discharge capability under high voltage loading.
• Regenerative braking circuits — Provides high‑voltage buffering and ripple handling for regenerative energy absorption and reuse.

Unique Advantages

• High‑voltage capability: 500 V rating (rated range up to DC 525 V) enables use in demanding DC link and inverter topologies.
• Designed for high ripple and frequency: Specified ripple currents at 120 Hz and 10 kHz make it appropriate for both low and high‑frequency regenerative environments.
• Extended high‑temperature life: 5000 hours at 105°C under rated conditions supports long‑term reliability in thermally stressed installations.
• Secure screw‑terminal mounting: Stud/bolt mount and radial screw terminals provide reliable high‑current connections and simplified assembly in power racks and enclosures.
• Compact high‑voltage form factor: Smaller sized within the LNU family, helping save board or chassis space without sacrificing voltage or capacitance.
• RoHS compliance: Meets RoHS directive requirements for material compliance in modern industrial designs.
