LNC2H182MSEG

The LNC2H182MSEG is an aluminum electrolytic capacitor in a screw-terminal radial can designed for high-voltage industrial power electronics. It delivers 1.8 mF capacitance at a 500 V rating and is part of Nichicon’s LNC series optimized for higher ripple current in a smaller package footprint.

Targeted for inverter and regenerative-power circuitry, this screw-terminal capacitor is intended for applications that require high ripple handling, fast charge–discharge endurance, and long operational life at elevated temperatures.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) nominal capacitance with a 500 V rated voltage and ±20% tolerance.
• Screw Terminal Mounting — Radial can with screw terminals for secure, low-impedance power connections in industrial power supplies.
• High Ripple Current — Rated ripple currents of 12.7 A at 120 Hz and 17.78 A at 100 kHz to handle both low- and high-frequency stress.
• Thermal & Lifetime Rating — Operating range −40 °C to +85 °C with a specified load life of 5000 hours at 85 °C under rated ripple current.
• Charge–Discharge Endurance — Designed to withstand charge–discharge testing (50 million cycles at ΔV = rated voltage × 0.3, 3 Hz) per the series specifications.
• 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), per datasheet limits.
• Polarized, Industrial Package — Polarized aluminum electrolytic design in a compact radial can (L: 9.0 cm × D: 6.35 cm) with screw terminals; height (seated max) 3.543 inch.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies — Bulk energy storage and smoothing in inverter circuits where high voltage and high ripple handling are required.
• AC Servomotor Regenerative Circuits — Suited for high-frequency regenerative voltage environments encountered in servomotor drives.
• High-Frequency Power Electronics — Handles high-speed charge–discharge loading typical of power-conversion and regenerative systems.
• General Power Electronics — Appropriate for industrial power supplies and applications needing robust high-voltage capacitors with long life at elevated temperatures.

Unique Advantages

• High-voltage energy storage: 500 V rating combined with 1.8 mF capacitance provides substantial bulk energy capacity for power conversion systems.
• High ripple capability: Specified ripple currents at both 120 Hz (12.7 A) and 100 kHz (17.78 A) enable reliable operation across a wide frequency range.
• Compact higher-ripple design: LNC series is specified as smaller-sized while delivering higher ripple current than LNX and LNK series, enabling space-constrained designs.
• Long elevated-temperature life: 5000-hour load life at 85 °C under rated ripple current supports sustained operation in industrial environments.
• Robust charge–discharge endurance: Qualified for extensive charge–discharge cycles (50 million cycles at specified ΔV and cycle rate) to address repetitive stress in regenerative applications.
• Standards compliance: RoHS compliance ensures conformity with current restricted-substances requirements.
