LNC2H682MSEJBN

The LNC2H682MSEJBN is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNC series, rated at 6800 µF and 500 V. It is a smaller‑sized, high ripple‑current radial can designed for industrial power electronics where high‑voltage energy storage, frequent charge/discharge and robust terminal connections are required.

Typical use cases include inverter circuitry, high‑frequency regenerative voltage circuits for AC servomotors, and general industrial power supplies where long life and high ripple capability are needed. The part combines high ripple current handling with a specified load life and wide operating temperature range to support demanding power applications.

Key Features

• High Capacitance and Voltage — 6800 µF nominal capacitance at a 500 V rated voltage for bulk energy storage in high‑voltage power systems.
• Screw Terminal Mounting — Radial can with screw terminals for secure, low‑impedance connections suitable for heavy current paths.
• High Ripple Current — Rated ripple current of 30 A at 120 Hz and 42 A at 100 kHz, enabling handling of significant AC currents in inverter and regenerative circuits.
• Temperature Range and Life — Operating temperature −40 °C to +85 °C with a rated load life of 5000 hours at 85 °C under applied ripple current.
• Durability under Cycling — Endurance for charge‑discharge behavior specified for 50 million cycles (ΔV = rated voltage × 0.3 at 3 Hz), supporting high‑speed charge/discharge applications.
• Leakage and Reliability Specs — Leakage current after 5 minutes is specified as not more than 3√V (µA) or 5 mA, whichever is smaller (at 20 °C); insulation resistance >100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V, 1 minute.
• Capacitance Tolerance and Low‑Temp Stability — Capacitance tolerance ±20% (120 Hz, 20 °C); impedance ratio Z(−40 °C)/Z(+20 °C) up to 8 for rated voltages 350–500 V.
• RoHS Compliant — Manufactured in compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Bulk energy storage and ripple handling for inverter DC link circuits in industrial motor drives.
• AC Servomotor Regeneration — High‑frequency regenerative voltage buffering for servo systems and regenerative braking circuits.
• Power Supplies — High‑voltage smoothing and charge/discharge buffering in industrial power supplies and converters.
• High‑Speed Charge/Discharge Systems — Applications requiring frequent, high‑speed charge/discharge cycles benefit from the specified endurance rating.
