LNC2G392MSEH

The LNC2G392MSEH is a screw-terminal aluminum electrolytic capacitor designed for industrial power electronics where high voltage, high ripple handling and long-term endurance are required. It is a member of Nichicon's LNC series and combines a compact can-style package with screw terminals for secure, low-impedance connections.

Targeted at inverter circuitry and regenerative power applications, this 3.9 mF, 400 V capacitor offers a rated operating range of –40 °C to +85 °C and a load life of 5000 hours at 85 °C under applied ripple current, delivering reliable performance in demanding industrial power supplies and motor-control systems.

Key Features

• Screw Terminal Mounting Robust screw terminals provide secure electrical and mechanical connection for high-current bus applications and field serviceability.
• High Capacitance and Voltage 3.9 mF (3900 µF) rated at 400 V to support energy buffering and DC-link functions in inverter and power-conversion stages.
• High Ripple Current Capability Rated ripple current of 17.1 A at 120 Hz and 23.94 A at 100 kHz enables handling of both low-frequency and high-frequency ripple in regenerative and inverter circuits.
• Long Load Life at Elevated Temperature Endurance specification of 5000 hours at 85 °C with rated ripple current applied, with performance limits defined for capacitance, tan δ and leakage current.
• Wide Operating Temperature Range Specified for –40 °C to +85 °C to accommodate a broad set of industrial environments.
• Compact, High-Energy Can φ76.2 × 80 mm can-style package provides high capacitance in a relatively small footprint compared with earlier LNX/LNK series units.
• RoHS Compliant Conforms to RoHS directives (2011/65/EU, (EU)2015/863), suitable for applications requiring restricted-substance compliance.
• Controlled Leakage and Tolerance Capacitance tolerance ±20% and leakage current specified as not more than 3√V µA or 5 mA after 5 minutes at 20 °C, providing predictable behavior for DC-link designs.

Typical Applications

• Industrial Power Supplies Used as DC-link and smoothing capacitors in inverter power supplies where sustained ripple and energy buffering are required.
• AC Servomotor Drives Suited for regenerative voltage handling and high-frequency ripple seen in motor-control and drive systems.
