LNC2G682MSEHBB

The LNC2G682MSEHBB is a screw-terminal aluminum electrolytic capacitor designed for high-ripple industrial power applications. Built in a radial can with screw terminals, it delivers 6.8 mF capacitance at a 400 V rating and is optimized for inverter and regenerative voltage circuits.

Its combination of high ripple-current capability, long life at elevated temperature, and compact footprint makes it well suited for industrial power supplies, AC servomotor drives, and general inverter systems where robust energy storage and frequent charge–discharge cycling are required.

Key Features

• Capacitance & Rated Voltage — 6.8 mF (6800 µF) nominal capacitance at a 400 V rated voltage with tolerance ±20%.
• Screw Terminal Mounting — Radial can with screw terminals for secure, high-current connections and easy installation in power assemblies.
• High Ripple Current — Low-frequency ripple current 23.1 A (120 Hz) and high-frequency ripple current 32.34 A (100 kHz), supporting heavy ripple loading and fast charge–discharge cycles.
• Long Endurance — Rated load life of 5000 hours at 85°C under rated ripple conditions, meeting endurance requirements for continuous industrial operation.
• Thermal Performance — Operating temperature range from −40°C to +85°C for broad environmental tolerance in industrial installations.
• Low Dissipation Factor — Tangent of loss angle (tan δ) 0.2 measured at 20°C, 120 Hz, indicating controlled dielectric losses for power applications.
• Leakage Current — Specified leakage current of 4940 µA, as measured after voltage application.
• Compact Physical Size — Cylindrical case ϕ76.2 × 120 mm length, providing a smaller-sized, higher-ripple-current solution compared to prior LNC family variants.
• Compliance & Packaging — RoHS compliant and shipped in cardboard packing; product is in mass production by Nichicon.

Typical Applications

• Industrial Inverters — Energy storage and smoothing for inverter DC link circuits, where high ripple tolerance and endurance are required.
• AC Servo Drives — Handling high-frequency regenerative voltages and rapid charge–discharge cycles in servo motor drives.
• Power Supplies — Bulk capacitance and ripple filtering for industrial power supplies used in automation and drive systems.
• High-Speed Charge–Discharge Systems — Suitable where frequent, high-rate charge–discharge loading is present due to its higher ripple capability.

Unique Advantages

• High ripple-handling in a compact can — Delivers substantial low- and high-frequency ripple currents (23.1 A @120 Hz, 32.34 A @100 kHz) while maintaining a smaller physical footprint.
• Designed for continuous industrial duty — 5000 hours of rated life at 85°C under ripple load supports long-term operation in demanding environments.
• Robust, serviceable connections — Screw terminals allow secure high-current wiring and straightforward maintenance or replacement.
• Wide operating temperature range — −40°C to +85°C rating provides flexibility across varied industrial ambient conditions.
• Measurable low loss — tan δ of 0.2 (20°C, 120 Hz) indicates controlled loss characteristics for efficient power handling.
• Regulatory and production readiness — RoHS compliant and available in mass production from Nichicon, enabling predictable sourcing and compliance.
