LNU2H222MSEHBN

The LNU2H222MSEHBN is an aluminum electrolytic capacitor in a screw-terminal radial can designed for high-voltage industrial power applications. As part of Nichicon's LNU series, this 2200 µF, 500 V polarized capacitor is optimized for inverter circuitry, high-frequency regenerative circuits for AC servomotors, and general inverter power supplies.

Key value comes from a compact high-voltage design with a rated operating range to 500 V for this part (series rated up to DC 525 V), a long load life at elevated temperature, and ripple-current performance suited to high-speed charge–discharge and high-frequency regenerative voltage environments.

Key Features

• Capacitance and Voltage: 2.2 mF (2200 µF) nominal capacitance with a rated voltage of 500 V; capacitance tolerance ±20% (120 Hz, 20°C).
• High-temperature endurance: Rated for continuous operation from −40°C to +105°C with a specified load life of 5000 hours at 105°C under rated ripple and DC bias conditions.
• High ripple-current capability: 8.5 A at 120 Hz and 11.9 A at 10 kHz to support demanding AC and regenerative switching waveforms.
• Screw terminal, radial can package: Robust screw-terminal mounting for secure connections in power assemblies; supplied with separate bracket packaging per series drawing.
• Leakage and insulation characteristics: Leakage current after 5 minutes ≤ 3√(C·V) µA or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Compact physical profile: Size L: 9.5 cm × D: 7.62 cm with a maximum seated height of 3.74 in—smaller-sized construction compared with the LNT series.
• Durability under charge–discharge cycling: Endurance for charge–discharge behavior tested for 50 million cycles (ΔV = rated voltage ±0.3, cycle 3 Hz) with retained capacitance and leakage characteristics per series specification.
• Environmental compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies: Energy storage and smoothing in inverter front-ends and DC-link circuits for industrial drives.
• AC servomotor regenerative circuits: Handling high-frequency regenerative voltages and rapid charge–discharge events in servo drive systems.
• General inverter designs: Bulk capacitance and ripple handling in general-purpose inverter and power conversion topologies.
• High-speed charge–discharge systems: Systems requiring repeated high-frequency switching where endurance and ripple capability are critical.

Unique Advantages

• High-voltage capability in a smaller footprint: Delivers 500 V rating (series up to DC 525 V) with reduced size compared to prior LNT-family parts, saving board and chassis space.
• Long high-temperature life: 5000 hours at 105°C under rated ripple and bias provides predictable lifetime performance for industrial applications.
• Engineered for high ripple and frequency: Specified ripple-current ratings at 120 Hz and 10 kHz enable reliable operation under both low- and high-frequency switching conditions.
• Robust mechanical termination: Screw-terminal construction facilitates secure, low-impedance connections in heavy-current power assemblies.
• Proven charge–discharge durability: Series-tested for 50 million charge–discharge cycles to meet endurance requirements in cyclic regenerative environments.
• Regulatory compliance: RoHS conformity supports environmental requirements for industrial equipment.
