LNC2G222MTEG

The LNC2G222MTEG is an aluminum electrolytic capacitor in a screw-terminal (stud) mount designed for industrial power applications. It delivers 2200 µF at a 400 V rating with a −40 °C to 85 °C operating range and is part of Nichicon's LNC series.

Engineered for inverter and regenerative circuits, this capacitor emphasizes higher ripple-current capability in a smaller package, with a rated load life of 5000 hours under ripple at 85 °C.

Key Features

• Electrolytic construction – Screw terminal (stud mount): Stud bolt mount with radial can and screw terminals for secure mechanical and electrical connection in power assemblies.
• Rated electrical capacity: 2200 µF capacitance with ±20% tolerance at 120 Hz, 20 °C, and 400 V rated voltage.
• High ripple-current capability: Rated ripple currents of 12.8 A at 120 Hz and 17.92 A at 100 kHz support heavy AC and switching loads.
• Thermal and lifetime performance: Operating temperature −40 °C to 85 °C with load-life specification of 5000 hours at 85 °C under rated ripple current.
• Charge–discharge endurance: Designed to withstand high-speed charge-discharge loading and validated for 50 million charge-discharge cycles (ΔV = rated × 0.3, 3 Hz) at room temperature.
• Electrical robustness: Leakage current specification after 5 minutes is not more than 3√V µA or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V for 1 minute between terminal and bracket with no abnormality.
• Smaller-sized, higher ripple than comparable LNX/LNK types: Part of the LNC series optimized for a compact form factor while delivering elevated ripple handling.
• Regulatory compliance: Compliant with RoHS directives (2011/65/EU, (EU)2015/863).
• Package dimensions: Nominal length 7.0 cm × diameter 6.35 cm; height seated maximum 2.756 inches (for mechanical planning).

Typical Applications

• Industrial inverter power supplies: Bulk smoothing and ripple handling in inverter front-ends where 400 V DC rails and sustained ripple are present.
• AC servomotor regenerative circuits: Absorbing high-frequency regenerative voltages and supporting rapid charge–discharge events in motor drive systems.
• General inverter systems: Energy storage and transient suppression in general-purpose inverter topologies requiring stud-mounted capacitors.

Unique Advantages

• High ripple performance: Specified ripple currents at both low and high frequencies (12.8 A @120 Hz, 17.92 A @100 kHz) support demanding switching environments.
• Compact, stud-mount form: Smaller-sized design compared with LNX/LNK series provides space savings while maintaining elevated ripple capability.
• Long operational life under load: 5000-hour load-life rating at 85 °C under rated ripple current enables reliable service in continuous-duty power systems.
• Durable under repeated switching: Proven endurance for high-frequency charge–discharge cycles (50 million cycles at specified test conditions) for regenerative and pulsed applications.
• Measured electrical safeguards: Defined leakage current limits, insulation resistance, and voltage-proof tests give clear, verifiable electrical margins for system design.
• Regulatory conformity: RoHS compliance supports use in regulated supply chains and assemblies.
