LNC2V103MSEJ

The LNC2V103MSEJ is an aluminum electrolytic capacitor in a screw-terminal radial can designed for industrial power electronics. It delivers 10,000 µF at 350 V in a φ90 × 100 mm package and is optimized for inverter circuitry, high-frequency regenerative voltage and other demanding charge/discharge loads.

Engineered for high ripple environments, this Nichicon LNC series part offers a smaller size and higher ripple-current capability compared with the LNX/LNK series, together with a 5,000-hour load life at 85°C when subjected to rated ripple current.

Key Features

• Capacitance & Voltage — 10,000 µF (10 mF) rated at 350 V; capacitance tolerance ±20% (120 Hz, 20°C).
• Screw Terminal Mount — Radial can with screw terminals for secure electrical and mechanical connections in power assemblies.
• High Ripple-Current Handling — Rated ripple current: 27.1 A at 120 Hz and 37.94 A at 100 kHz, supporting heavy AC loading and high-frequency operation.
• Thermal & Environmental Range — Operating temperature range −40°C to +85°C; RoHS compliant (2011/65/EU, (EU)2015/863).
• Reliability & Endurance — Load life: 5,000 hours at 85°C with DC bias plus rated ripple current; endurance for charge–discharge behavior tested to 50 million cycles (ΔV = rated × 0.3, 3 Hz).
• Leakage, Insulation & Withstand — Leakage current after 5 minutes not more than 3√V (µA) or 5 mA (whichever is smaller) at 20°C; insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V, 1 minute voltage proof between terminal and bracket.
• Package Dimensions — φ90 × 100 L (approx. L: 10 cm × D: 9 cm) can; printed white marking on black sleeve for identification.

Typical Applications

• Industrial Inverters — Energy storage and smoothing for inverter power supplies where high voltage and high ripple capability are required.
• AC Servomotor Drives — Handles high-frequency regenerative voltage and frequent charge/discharge cycles in motor control systems.
• High-Speed Charge/Discharge Loads — Suited for applications that demand rapid energy transfer and robust cycling endurance.

Unique Advantages

• High ripple-current capacity: Supports heavy AC ripple and high-frequency operation with specified ripple current at 120 Hz and 100 kHz, improving system stability under load.
• Compact for its class: Smaller-sized design compared to LNX/LNK series while delivering comparable or higher ripple capability, helping save enclosure space.
• Long operational life at elevated temperature: 5,000-hour load life at 85°C under rated ripple conditions provides predictable performance for industrial deployments.
• Proven charge–discharge endurance: Validated to withstand 50 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz), reducing maintenance and replacement frequency in cyclic applications.
• Robust electrical safety margins: Defined leakage, insulation resistance and voltage-proof characteristics support reliable integration into high-voltage systems.
• Regulatory compliance: RoHS-compliant construction meets common environmental requirements for industrial equipment.
