LNC2G103MSEHBN

The LNC2G103MSEHBN is an aluminum electrolytic capacitor in a screw-terminal radial can package, designed for industrial power electronics. It delivers 10 mF capacitance at a 400 V rating and is optimized for inverter and regenerative applications where high ripple current and compact size are required.

Part of Nichicon's LNC series, this device offers a -40 °C to +85 °C operating range, a 5000 hour load life at 85 °C under rated ripple conditions, and construction suited for high-speed charge–discharge and high-frequency regenerative voltages used in AC servomotors and general inverters.

Key Features

• Capacitance & Voltage — 10 mF nominal capacitance at a 400 V DC rating, with a tolerance of ±20%.
• Screw Terminal Mounting — Radial can with screw terminals for robust, serviceable connections in power assemblies.
• High Ripple Current Capability — Rated ripple current of 29.5 A at 120 Hz and 41.3 A at 100 kHz, supporting heavy AC and high-frequency loads.
• Thermal and Lifetime Performance — Operates from −40 °C to +85 °C with a specified load life of 5000 hours at 85 °C when ripple current is applied.
• Compact, High‑Power Design — Smaller-sized and higher ripple current characteristics compared with prior LNX/LNK models in the LNC series.
• Leakage and Insulation — Leakage current after 5 minutes at 20 °C is limited to not more than 3√(V) μA or 5 mA (whichever is smaller); insulation resistance is greater than 100 MΩ at DC 500 V between terminal and bracket.
• Voltage Withstand & Endurance — No abnormality under AC 2500 V for 1 minute between terminal and bracket; endurance requirements met after 5000 hours of DC bias plus rated ripple current at 85 °C.

Typical Applications

• Industrial Inverters — Bulk energy storage and smoothing for inverter power stages in industrial drives and power supplies.
• AC Servomotor Systems — Handling high-frequency regenerative voltages and rapid charge–discharge cycles in servo amplifier subsystems.
• High-Frequency Power Electronics — Filtering and decoupling in high-frequency regenerative or switching environments thanks to rated ripple at 100 kHz.
• General Power Supplies — Robust energy buffering and ripple mitigation where long life at elevated temperature and heavy ripple load are required.

Unique Advantages

• High ripple endurance: Rated for 29.5 A at 120 Hz and 41.3 A at 100 kHz, enabling reliable operation under heavy AC and high-frequency stress.
• 5000‑hour load life at 85 °C: Designed to maintain capacitance, tan δ, and leakage current within specified limits after prolonged ripple-loaded operation at elevated temperature.
• Compact high-power form factor: Smaller-sized design compared with LNC series predecessors (LNX, LNK) while delivering higher ripple capability for space-constrained power racks.
• Robust electrical isolation: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V proof testing between terminal and bracket enhance safety and assembly reliability.
• Durable charge–discharge performance: Meets series endurance criteria after extensive charge–discharge cycling, supporting applications with frequent energy transfers.
• Regulatory compliance: RoHS compliant (2011/65/EU, (EU)2015/863), simplifying environmental reporting and procurement requirements.
