LNC2H122MSEG

The LNC2H122MSEG is a screw-terminal aluminum electrolytic capacitor designed for high-voltage energy storage in industrial power electronics. As a radial can with screw terminals, it delivers 1.2 mF (1200 µF) capacitance at a 500 V rating and is polarized for DC applications.

Engineered for inverter and regenerative power circuitry, this capacitor combines a smaller-sized package with elevated ripple-current capability and long load life, making it suitable for industrial power supplies, AC servomotor regeneration, and general inverter applications.

Key Features

• High voltage & capacitance — 1.2 mF (1200 µF) capacitance rated at 500 V for high-voltage DC bus and energy storage applications.
• Screw terminal mounting — Radial can with screw terminals for secure, low-inductance connections in power assemblies and easy integration into industrial enclosures.
• High ripple-current performance — Rated ripple current of 10.4 A at 120 Hz and 14.56 A at 100 kHz, supporting high-frequency and high-power charge/discharge conditions.
• Thermal and lifetime characteristics — Operating temperature range −40°C to +85°C with a specified load life of 5000 hours at 85°C when subjected to rated ripple current.
• Reliability and endurance — Endurance validated by DC bias plus rated ripple-current testing (5000 hours at 85°C) and charge/discharge endurance tests (50 million cycles at room temperature with ΔV = 0.3 × rated voltage).
• Leakage and insulation specifications — Leakage current after 5 minutes is limited to 3√V (µA) or 5 mA whichever is smaller (at 20°C); insulation resistance more than 100 MΩ at DC 500 V between terminal and bracket; AC 2500 V, 1 minute voltage proof between terminal and bracket.
• Compact footprint — Smaller-sized design compared with LNX and LNK series while maintaining higher ripple capability; physical size L: 7 cm × D: 6.35 cm and radial can package for space-efficient installations.
• Environmental compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies — Bulk and smoothing capacitance on DC buses for inverter modules where 500 V rating and high ripple handling are required.
• AC servomotor regenerative circuits — Energy absorption and regeneration support for high-frequency regenerative voltages in motor drives.
• High-speed charge/discharge systems — Suitable for circuits subject to rapid charge-discharge cycles, validated by extensive cycle endurance testing.
• General power conversion — Use in industrial power supplies and converters that demand durable, high-voltage electrolytic capacitance in a screw-terminal form factor.

Unique Advantages

• Compact high-voltage energy storage: 1.2 mF at 500 V in a smaller-sized can reduces board area compared with older series while delivering required DC bus capacitance.
• Enhanced ripple handling: Specified ripple currents at both low and high frequencies (10.4 A at 120 Hz, 14.56 A at 100 kHz) enable reliable operation under demanding AC and switching conditions.
• Proven long-term performance: 5000-hour load-life rating at 85°C under rated ripple current provides predictable aging and planning for maintenance intervals.
• Robust charge/discharge endurance: Qualification for 50 million charge/discharge cycles at room temperature supports applications with frequent energy cycling.
• Safety and isolation characteristics: High insulation resistance and 2500 V AC voltage-proof between terminal and bracket help maintain system isolation and safety margins.
• Regulatory compliance: RoHS compliance ensures alignment with common environmental requirements for industrial equipment.
