LNC2W123MSEJ

The LNC2W123MSEJ is a screw-terminal aluminum electrolytic capacitor designed for high-voltage power electronics. It delivers 12,000 µF at 450 V in a compact, radial can with screw terminals, tailored for industrial inverter and regenerative-power environments.

Engineered for high ripple-current loading and rapid charge–discharge cycles, this capacitor targets industrial power supplies, AC servomotor regenerative circuits and general inverter systems where long load life and high-frequency performance are required.

Key Features

• High-capacitance, high-voltage: 12,000 µF rated capacitance at 450 V for substantial energy storage in power-conversion circuits.
• Enhanced ripple-current capability: Rated ripple current of 38.2 A at 120 Hz and 53.48 A at 100 kHz to support high-load and high-frequency operation.
• Long load life under ripple: Load life specified as 5,000 hours when D.C. bias plus rated ripple current is applied at 85°C.
• Designed for high-speed charge–discharge: Constructed to cope with rapid charge–discharge loading and endurance of repetitive cycles per the series specification.
• Operating temperature range: –40°C to +85°C suitable for a wide range of industrial environments.
• Screw-terminal radial can package: Polarized, screw-terminal mounting for secure connections in power assemblies and easy servicing.
• Leakage and insulation characteristics: Leakage current specified as not more than 3√V (µA) or 5 mA (after 5 minutes at 20°C); insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Safety and durability tests: Meets voltage proof test of AC 2500 V for 1 minute between terminal and bracket and endurance criteria after applied bias and ripple for rated life.
• RoHS compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies: Bulk energy storage and ripple smoothing in inverter front-ends where 450 V DC bus capability is required.
• AC servomotor regenerative circuits: Handles high-frequency regenerative voltages and rapid charge–discharge cycles common in motor drive systems.
• General inverter systems: Energy buffering and ripple handling for general-purpose inverters in industrial automation.
• High-frequency power electronics: Supports high-frequency ripple currents up to 100 kHz for switching-regulator and regenerative applications.

Unique Advantages

• High-voltage energy storage: 450 V rating with 12,000 µF capacitance enables substantial DC-bus energy buffering without series stacking.
• High ripple-current tolerance: Specified 38.2 A (120 Hz) and 53.48 A (100 kHz) ripple capability reduces heating and extends service life in demanding power stages.
• Compact screw-terminal form factor: Radial can with screw terminals provides robust electrical connections and simplifies installation and maintenance in power racks.
• Proven operational life: 5,000-hour load-life rating at 85°C under rated ripple current gives predictable longevity for industrial deployments.
• Robust electrical integrity: Leakage, insulation resistance and voltage-proof specifications provide verifiable reliability for safety-critical power designs.
• Regulatory compliance: RoHS conformance supports eco-design and regulatory requirements for industrial equipment.
