LNC2G472MSEHBB

The LNC2G472MSEHBB is a screw-terminal aluminum electrolytic capacitor providing 4700 µF capacitance at a 400 V rating. It is a polarized, high-ripple-current capacitor in the Nichicon LNC series designed for demanding industrial power-conversion environments.

Designed for inverter and motor-drive power supplies, this smaller-sized LNC part delivers high ripple-current capability and a 5000-hour load life at 85°C, making it suitable for high-frequency regenerative and rapid charge–discharge applications.

Key Features

• Capacitance and Voltage: 4.7 mF (4700 µF) rated at 400 V, providing bulk energy storage for power-conversion circuits.
• Screw Terminal Mounting: Radial can with screw terminals for secure, low-impedance connections in power assemblies.
• High Ripple Current: Rated ripple current of 18.3 A at 120 Hz and 25.62 A at 100 kHz, suitable for high-frequency and regenerative applications.
• Long Load Life: Endurance specified as 5000 hours at 85°C under rated ripple current and DC bias, supporting sustained operation in industrial environments.
• Temperature Range: Operates from −40 °C to +85 °C to cover typical industrial ambient conditions.
• Compact Footprint: Physical size L: 9 cm × D: 7.62 cm for space-conscious power modules while providing high ripple handling compared to earlier LNX/LNK series.
• Robust Electrical Characteristics: Leakage current limit after 5 minutes follows the series specification (≤ 3√V μA or 5 mA, whichever is smaller at 20 °C); insulation resistance and voltage-proof characteristics are defined in the LNC series specifications.
• Polarized Design: Intended for DC power circuits where polarized electrolytic capacitors are required.
• RoHS Compliant: Meets RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies for Inverter Circuitry: Bulk smoothing and ripple handling in inverter DC-link stages for reliable power conversion.
• AC Servomotor Regenerative Circuits: Handles high-frequency regenerative voltage and rapid charge–discharge events in motor-drive systems.
• General Inverter Systems: Energy buffering and ripple suppression in general inverter topologies for industrial drives and power equipment.

Unique Advantages

• High ripple-current capability: Specified ripple currents at both low and high frequencies (18.3 A at 120 Hz, 25.62 A at 100 kHz) support high-frequency power stages and regenerative loads.
• Extended operational life under load: 5000-hour load-life rating at 85 °C under rated ripple current provides predictable long-term performance for industrial applications.
• Smaller-sized solution for power assemblies: The LNC series provides a reduced footprint compared with LNX and LNK while maintaining higher ripple performance, aiding compact power module designs.
• Designed for high-speed charge–discharge: Endurance for charge–discharge behavior is defined in the series specifications, supporting repeated rapid cycling in power systems.
• Industrial temperature range: −40 °C to +85 °C operation covers typical industrial ambient conditions for inverter and motor-drive equipment.
• Regulatory compliance: RoHS conformity supports deployment in markets requiring restricted-substance compliance.
