LNC2V123MSEJ

The LNC2V123MSEJ is a screw-terminal aluminum electrolytic capacitor from Nichicon, offering 12,000 µF capacitance at a 350 V rating. It is designed for industrial power applications where high ripple capability, robust charge-discharge endurance, and compact axial mounting are required.

Targeted at inverter power supplies and regenerative high-frequency circuitry such as AC servomotor drives and general inverters, this capacitor combines high ripple-current handling and a 5,000 hour load life at 85°C to support demanding power-electronics environments. It is RoHS compliant.

Key Features

• Capacitance & Voltage: 12,000 µF nominal capacitance at a 350 V rated voltage, suitable for bulk energy storage in high-voltage power rails.
• High Ripple-Current Performance: Rated ripple current of 30.1 A at 120 Hz and 42.14 A at 100 kHz, enabling effective handling of both low- and high-frequency ripple from inverter and regenerative circuits.
• Thermal and Lifetime Reliability: Operates across –40°C to +85°C with a rated load life of 5,000 hours at 85°C under applied ripple current.
• Mechanical & Mounting: Screw terminal radial can package (φ90×120L) for secure, low-impedance connections in industrial assemblies.
• Charge–Discharge Endurance: Designed to cope with high-speed charge/discharge loads; series endurance testing includes 50 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz) at room temperature.
• Polarized Electrolytic Construction: Polarized design with ±20% capacitance tolerance, suitable for DC energy storage and smoothing in power systems.

Typical Applications

• Industrial Inverter Power Supplies: Bulk energy storage and smoothing for inverter DC links, reducing voltage ripple and improving power-stage stability.
• AC Servomotor Regenerative Circuits: Handling high-frequency regenerative voltages and rapid charge–discharge cycles in motor drive systems.
• High-Frequency Regeneration and Power Electronics: Suitable for general inverter designs and power-conversion stages that require high ripple-current capability at elevated frequencies.

Unique Advantages
