LNC2H392MSEHBB

The LNC2H392MSEHBB is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNC series, rated at 3.9 mF (3900 µF) and 500 V. It is a radial can design with screw terminals engineered for industrial power systems that require high ripple handling and robust electrical connections.

Designed for inverter circuitry and high-frequency regenerative voltage applications such as AC servomotors and general inverters, this capacitor delivers extended endurance under rated ripple conditions and is compliant with RoHS requirements.

Key Features

• Capacitance & Rated Voltage — 3.9 mF (3900 µF) nominal capacitance at a 500 V rating for bulk energy storage in high-voltage power systems.
• Screw Terminal Mounting — Radial can with screw terminals for secure, low-inductance connections in high-current assemblies.
• High Ripple Current — Rated ripple current of 19.9 A at 120 Hz and 27.86 A at 100 kHz, supporting heavy AC loading and high-frequency operation.
• Endurance — Load life specified as 5000 hours with rated ripple current at 85°C, meeting endurance criteria after restoration to 20°C.
• Temperature Range — Operating temperature from −40°C to +85°C for broad industrial use.
• Electrical Losses and Leakage — Low tangent of loss angle (tan δ = 0.2) and measured leakage current of 4.18 mA as provided for initial condition assessment.
• Form Factor & Packing — φ76.2 × 120L can (L: 12 cm × D: 7.62 cm) supplied in cardboard packing for production handling.
• Regulatory Compliance — Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies (Inverter Circuits) — Provides bulk energy buffering and ripple handling in inverter power stages for industrial drives and converters.
• AC Servomotor Regenerative Systems — Suited for high-frequency regenerative voltage environments found in AC servomotor drives.
• General Inverters — Applicable where sustained ripple current and long endurance at elevated temperature are required.
• High-Speed Charge–Discharge Systems — Built to cope with high-speed charge–discharge loading for repeated dynamic energy transfers.

Unique Advantages

• High ripple-current capability: Explicit ratings at both low and high frequencies (19.9 A at 120 Hz, 27.86 A at 100 kHz) enable reliable operation under demanding AC ripple conditions.
• Smaller size for the class: Described as smaller-sized while delivering high ripple current compared with earlier LNC family variants LNX and LNK, supporting compact power-stage layouts.
• Proven endurance: 5000 hours life at 85°C under rated ripple current provides predictable aging behavior for industrial applications.
• Robust electrical connections: Screw terminal package simplifies secure high-current terminations and mechanical fastening in power assemblies.
• Low losses and controlled leakage: Specified tan δ and leakage current figures support predictable ESR-related heating and insulation behavior.
• RoHS compliance: Meets RoHS directive requirements for environmentally regulated applications.
