LNC2W102MSEF

The LNC2W102MSEF from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNC series, engineered for industrial power electronics. It delivers 1 mF (1000 μF) capacitance at a 450 V rating in a radial can with screw terminals, providing a compact solution for high-voltage energy buffering.

Designed for inverter circuitry and regenerative systems, this part offers higher ripple current capability and a reduced physical footprint compared with some prior series, with a rated load life of 5000 hours under ripple current at 85°C.

Key Features

• Electrical Rating — 1 mF (1000 μF) capacitance with a 450 V rated voltage, suitable for high-voltage DC bus applications.
• High Ripple Current Performance — Specified ripple current of 9.3 A at 120 Hz and 13.02 A at 100 kHz, enabling continuous handling of significant AC ripple in power circuits.
• Load Life & Endurance — Load life of 5000 hours at 85°C with rated ripple current applied; meets endurance criteria for capacitance, tan δ, and leakage current after life test.
• Charge–Discharge Robustness — Qualified for charge–discharge endurance (50 million cycles at ΔV = 0.3 × rated voltage, 3 Hz) with defined limits on capacitance change, tan δ, and leakage current.
• Temperature Range — Operational from –40°C to +85°C, matching typical industrial ambient requirements documented for the series.
• Mechanical & Mounting — Radial can with screw terminals for secure electrical and mechanical connections in industrial assemblies; printed marking in white on a black sleeve.
• Insulation & Voltage Withstand — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket and AC 2500 V, 1 minute voltage proof between terminal and bracket as specified.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies — Energy buffering and DC bus stabilization for inverter front-ends in industrial power supplies.
• AC Servomotor Regenerative Circuits — Handling high-frequency regenerative voltages and rapid charge–discharge events in servo drive systems.
• General Inverters — Bulk energy storage and ripple smoothing in general-purpose inverter designs.
• High-Speed Charge–Discharge Loads — Applications requiring repeated fast charge–discharge cycles, supported by the capacitor’s charge–discharge endurance specifications.

Unique Advantages

• Compact high-voltage energy storage: 1 mF at 450 V provides substantial DC bus capacitance in a smaller-sized LNC series package.
• High ripple handling: Rated ripple currents of 9.3 A (120 Hz) and 13.02 A (100 kHz) reduce temperature rise and improve reliability under AC loading.
• Proven long-term performance: 5000-hour load life at 85°C under rated ripple current gives predictable longevity for industrial installations.
• Durable under cycling: Endurance to 50 million charge–discharge cycles supports designs with frequent voltage swings.
• Robust insulation and voltage proof: High insulation resistance and AC 2500 V voltage proof between terminal and bracket support safe installation practices.
• Regulatory compliance: RoHS conformity for lead-restricted environments.
