LNC2G822MSEJBN

The LNC2G822MSEJBN is an aluminum electrolytic capacitor in a screw-terminal radial can designed for industrial power electronics. It delivers 8.2 mF (8200 µF) capacitance at a 400 V rating and is optimized for inverter and regenerative circuits used in industrial power supplies and AC servomotor systems.

Engineered for high ripple-handling, rapid charge–discharge loading and long operational life, this Nichicon LNC-series part supports high-frequency regenerative voltages and continuous operation up to 85 °C while meeting RoHS requirements.

Key Features

• Capacitance and Voltage — 8.2 mF (8200 µF) rated at 400 V, providing bulk energy storage for power conversion and regenerative applications.
• High ripple current capability — Rated ripple current of 29.5 A at 120 Hz and 41.3 A at 100 kHz to support heavy AC and high-frequency loading.
• Screw-terminal mounting — Robust screw terminals and radial can package enable secure, low-impedance, high-current connections for industrial power systems.
• Wide operating temperature — Specified for −40 °C to +85 °C operation to accommodate demanding industrial environments.
• Extended load life — Endurance rating of 5000 hours under applied rated ripple current at 85 °C, supporting sustained operation in inverter circuitry.
• Charge–discharge endurance — Designed to withstand 50 million charge–discharge cycles (ΔV = rated voltage × 0.3, cycle 3 Hz) without exceeding specified limits for capacitance, tan δ, or leakage.
• Leakage and reliability specs — Leakage current after 5 minutes is limited to 3√V μA or 5 mA, whichever is smaller, and insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket.
• RoHS compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements.
• Compact footprint — Smaller-sized and higher ripple current performance compared to Nichicon LNX/LNK series; physical footprint dimensions L: 10.5 × D: 9 cm for space-conscious designs.

Typical Applications

• Industrial power supplies (inverter circuitry) — Provides bulk energy storage and ripple filtering for inverter front-ends and DC bus stabilization.
• AC servomotor regenerative circuits — Handles high-frequency regenerative voltage and rapid charge–discharge events typical in motor drives.
• General inverter systems — Supports continuous ripple currents and long run times required by industrial inverter topologies.
• High-frequency charge–discharge systems — Suited to applications that require repeated high-speed switching and energy recovery.

Unique Advantages

• High ripple tolerance: Rated ripple currents up to 41.3 A at 100 kHz reduce thermal stress and improve reliability in high-frequency circuits.
• Long operational life under load: 5000‑hour endurance at 85 °C under rated ripple current supports extended service intervals in industrial equipment.
• Screw-terminal reliability: Screw terminals provide secure electrical and mechanical connections for high-current distribution in power racks and inverters.
• Charge–discharge robustness: Certified for 50 million charge–discharge cycles, enabling longevity in applications with frequent energy cycling.
• Regulatory compliance: RoHS conformity simplifies integration into systems that require restricted-substance compliance.
• Space-efficient design: Smaller than comparable LNX/LNK series parts while delivering high capacitance and ripple capability, helping reduce system footprint.
