The LNC2G682MSEG is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNC series, offering 6.8 mF (6800 µF) capacitance at a 400 V rating. It is a smaller-sized, high-ripple design intended for demanding industrial power conversion environments.

Designed for inverter and regenerative applications, the LNC2G682MSEG supports high-frequency loading and fast charge–discharge cycles while delivering a rated load life of 5000 hours at 85°C. The part is RoHS compliant.

Key Features

• Rated Capacitance & Voltage — 6.8 mF (6800 µF) at 400 V nominal, suitable for bulk energy storage in power-conversion circuits.
• High ripple-current capability — Specified ripple current of 23.8 A at 120 Hz and 33.32 A at 100 kHz, supporting heavy AC ripple and high-frequency switching environments.
• Temperature and lifetime — Operating range −40°C to +85°C with a rated load life of 5000 hours at 85°C under applied ripple current.
• Endurance and charge–discharge robustness — Designed to withstand high-speed charge–discharge loading; datasheet endurance tests include 50 million charge–discharge cycles at room temperature with defined ΔV and cycle conditions.
• Mounting and package — Screw terminal, radial can construction for secure connections in power assemblies and easy installation in industrial equipment.
• Leakage and insulation — Leakage current specified after 5 minutes as not more than 3√V (µA) or 5 mA (whichever is smaller); insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket per datasheet.
• Size and form factor — Compact footprint for its class; physical dimensions listed as L: 16.5 cm × D: 6.35 cm, enabling smaller assemblies compared with earlier LNX/LNK series options.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverters and power supplies — Bulk energy storage and ripple filtering for inverter front-ends and industrial DC bus systems.
• AC servomotor drives — Handles high-frequency regenerative voltages and rapid charge–discharge cycles common in servo and motion-control systems.
• General inverter systems — High ripple and endurance characteristics suit utility and industrial inverter topologies.
• High-frequency switching circuits — Elevated ripple-current ratings at 100 kHz make this capacitor appropriate for high-speed switching and regenerative power circuits.

Unique Advantages

• High ripple-current handling: Rated 23.8 A at 120 Hz and 33.32 A at 100 kHz, enabling reliable operation under large AC ripple and high-frequency switching.
• Smaller-sized solution: Reduced physical footprint compared to earlier LNX/LNK series designs while maintaining ripple and lifetime performance, helping save space in power assemblies.
• Long elevated-temperature life: 5000 hours load life at 85°C under rated ripple current, providing predictable service life in hot industrial environments.
• Robust charge–discharge endurance: Demonstrated resistance to repeated high-speed charge–discharge cycles (datasheet test: 50 million cycles), supporting applications with frequent energy reversals.
• Screw-terminal mounting: Secure, low-inductance connections suitable for high-current power paths in industrial equipment.
• Regulatory compliance: RoHS conformant for regulatory alignment in global equipment builds.
