The LNC2G103MSEJ is a screw-terminal aluminum electrolytic capacitor designed for industrial power electronics. It provides high ripple-current capability in a compact radial can package, making it suitable for inverter power supplies and high-frequency regenerative circuits.

Engineered for robust operation from –40°C to +85°C, this polarized capacitor delivers a 5000-hour load life at 85°C under rated ripple conditions and is RoHS compliant.

Key Features

• High Capacitance & Voltage — 10 mF nominal capacitance rated at 400 V for bulk energy storage in power conversion and DC-link applications.
• High Ripple Current Handling — Rated ripple current of 33.2 A at 120 Hz and 46.48 A at 100 kHz to support inverter and regenerative loads.
• Screw Terminal Mounting — Radial can with screw terminals for secure electrical and mechanical connection in industrial assemblies.
• Wide Operating Temperature — Specified for operation from –40°C to +85°C to meet typical industrial environment requirements.
• Long Endurance — Load life of 5000 hours at 85°C when subjected to rated DC bias plus rated ripple current.
• Charge–Discharge Durability — Qualified for endurance of charge–discharge behavior (50 million cycles at ΔV = rated × 0.3, 3 Hz) to tolerate frequent switching stress.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited to 3√V (µA) or 5 mA, whichever is smaller (at 20°C).
• Compact Footprint — Smaller-sized, higher ripple current construction compared with related series, supplied with radial can and screw terminals (size: L: 12 × D: 9 cm).
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — DC-link and energy storage in inverter circuitry for motor drives and power conversion systems.
• Regenerative Servo Systems — High-frequency regenerative voltage handling for AC servomotor drives and recuperative power stages.
• High-Speed Charge–Discharge Circuits — Applications requiring rapid charge and discharge cycles where endurance and high ripple capability are required.
• Industrial Power Supplies — Bulk filtering and smoothing in high-power industrial supplies subject to elevated ripple currents.
