LNC2W682MSEHBB

The LNC2W682MSEHBB is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNC series. It delivers 6.8 mF (6800 µF) nominal capacitance at 450 V in a radial can with screw terminals, optimized for high ripple and high‑speed charge/discharge conditions.

Designed for industrial power electronics, this capacitor targets inverter circuitry and regenerative power stages that require long load life, high ripple handling, and a compact footprint relative to comparable LNC series parts.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) nominal capacitance rated at 450 V with ±20% tolerance at 120 Hz, 20°C.
• Screw Terminal Mounting — Robust screw‑terminal radial can package for secure high‑current connections in power supply and inverter assemblies.
• High Ripple Current — Rated ripple current of 23.8 A at 120 Hz and 33.32 A at 100 kHz, supporting high‑frequency and regenerative duty.
• Load Life — Endurance specified as 5000 hours with rated DC bias plus rated ripple current at 85°C; capacitors meet defined capacitance, tan δ and leakage current requirements after life test.
• Wide Temperature Range — Operating range –40°C to +85°C suitable for industrial environments.
• Robust Electrical Integrity — Insulation resistance >100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V for 1 minute with no abnormality.
• Designed for Repetitive Charge/Discharge — Endurance for charge/discharge behavior verified to 50 million cycles (ΔV = rated voltage × 0.3, 3 Hz) at room temperature.
• RoHS Compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — DC link and smoothing in general inverters where sustained ripple handling and long life at 85°C are required.
• AC Servomotor Regeneration — High‑frequency regenerative voltage applications that demand robust charge/discharge performance and high ripple current capability.
• Power Supply Systems — Bulk energy storage and ripple filtering in industrial power supplies for motor drives and power conversion equipment.

Unique Advantages
