LNC2V392MSEG

The LNC2V392MSEG is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNC series designed for industrial power electronics. It is a polarized, radial can capacitor optimized for inverter circuitry, high-frequency regenerative voltage and other industrial power-supply applications where compact size and high ripple handling are required.

Key value comes from a combination of high ripple-current capability, a 350 V rated voltage, and proven endurance under DC bias plus ripple at elevated temperature—making it suitable for demanding charge/discharge and regenerative environments.

Key Features

• Capacitance & Voltage — 3.9 mF capacitance with a 350 V rated voltage and ±20% tolerance for predictable DC-link energy storage.
• Screw Terminal Packaging — Radial can with screw terminals for secure, low-impedance power connections in industrial assemblies.
• High Ripple Current — Rated ripple current of 14.9 A at 120 Hz and 20.86 A at 100 kHz, supporting heavy AC ripple and high-frequency switching loads.
• Operating Temperature & Lifetime — Specified for –40°C to +85°C with a rated load life of 5000 hours at 85°C under applied ripple current.
• Robust Endurance — Meets charge–discharge endurance tests including 50 million cycles (ΔV = rated × 0.3, 3 Hz) while remaining within specified limits for capacitance, tan δ and leakage current.
• Leakage & Insulation — Leakage current limit defined as not more than 3√V (µA) or 5 mA (whichever is smaller) after 5 minutes at 20°C; insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Safety & Voltage Withstand — No abnormality at AC 2500 V applied for 1 minute between terminal and bracket.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint — Smaller-sized design in the LNC series compared with LNX/LNK series while providing higher ripple-current capability; physical size L: 8.5 × D: 6.35 cm.

Typical Applications

• Industrial Inverters — DC-link and energy-buffering in inverter power stages where high ripple currents and frequent charge/discharge cycles occur.
• AC Servomotor Drives — Handling high-frequency regenerative voltages and fast charge/discharge demands in servo drive regenerative circuits.
• Power Supplies for Motor Control — Bulk energy storage and ripple smoothing in industrial motor-control power supplies and drive electronics.
• High-Frequency Regenerative Systems — Applications requiring sustained performance under high-frequency switching and regenerative loading conditions.

Unique Advantages

• High ripple-current tolerance: Rated for 14.9 A at 120 Hz and 20.86 A at 100 kHz, enabling reliable operation under heavy AC ripple and switching stress.
• Proven endurance under load: 5000 hours at 85°C under DC bias plus rated ripple current gives predictable long-term performance in elevated-temperature environments.
• Designed for fast charge/discharge: Endurance test of 50 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz) supports frequent switching and regenerative use cases.
• Robust electrical isolation: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V withstand testing between terminal and bracket for reliable installation integrity.
• Space-efficient form factor: Smaller-sized LNC series design delivers higher ripple capability in a compact radial can with screw terminals for secure mounting.
• RoHS compliant: Meets current RoHS requirements for environmental and regulatory conformance.
