LNC2H182MSEGBB

The LNC2H182MSEGBB is an aluminum electrolytic, screw-terminal capacitor designed for high-ripple, high-voltage industrial power applications. It combines a 1.8 mF (1800 µF) capacitance with a 500 V rated voltage in a radial can with screw terminals suitable for heavy-duty power assemblies.

Targeted at inverter circuitry and regenerative power stages, this capacitor offers high ripple-current capability, long load life, and temperature range suitable for industrial environments, supporting demanding charge–discharge and high-frequency loading conditions.

Key Features

• Electrical Rating: 1.8 mF (1800 µF) capacitance at 500 V rated voltage with ±20% tolerance.
• High ripple-current capability: Specified ripple current of 12.7 A at 120 Hz and 17.78 A at 100 kHz for heavy AC and high-frequency loading.
• Temperature and endurance: Operating range –40°C to +85°C and load life of 5000 hours at 85°C under rated ripple current and DC bias.
• Mechanical and mounting: Screw-terminal radial can package for robust panel or bracket mounting; physical size L: 9.0 cm × D: 6.35 cm and seated height max 3.543 in.
• Polarized design: Electrolytic, polarized capacitor suitable for DC bias use.
• Insulation and voltage proof: Insulation resistance of more than 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket.
• Endurance and charge–discharge robustness: Meets capacitance/tan δ/leakage current retention after 5000 hours at 85°C and after 50 million charge–discharge cycles (ΔV = 0.3 × rated V, 3 Hz).
• Regulatory compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies: Energy storage and smoothing in inverter power supplies where high voltage and high ripple handling are required.
• AC servomotor regenerative circuits: Support for high-frequency regenerative voltage and energy absorption in drive systems.
• General inverter systems: Bulk and smoothing capacitor for inverter stages in industrial motor drives and power conversion modules.
• High-speed charge–discharge circuits: Circuits that experience rapid charge and discharge cycles and require capacitors specified for endurance under such loading.

Unique Advantages

• High ripple-current handling: Rated ripple currents at 120 Hz and 100 kHz support both low- and high-frequency loading scenarios common in inverter and regenerative circuits.
• Long operational life under load: 5000-hour load-life rating at 85°C provides predictable performance for industrial applications operating at elevated temperatures.
• Compact form for its performance class: Designed to be smaller sized while delivering high ripple capability compared with related LNC-series references, helping conserve panel and chassis space.
• Robust insulation and voltage proof: High insulation resistance and AC 2500 V withstand rating between terminal and bracket improve system-level safety margins during qualification testing.
• Designed for repeated charge–discharge: Validated for 50 million charge–discharge cycles (ΔV = 0.3 × rated V), demonstrating suitability for applications with frequent energy transfer events.
• Regulatory compliance: RoHS conformity simplifies selection for designs requiring restricted-substance compliance.
