LNU2H272MSEGBB

The LNU2H272MSEGBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNU series, delivering 2700 µF at a 500 V rated voltage with ±20% tolerance. Engineered for high-voltage power electronics, it targets industrial inverter and regenerative-power applications where high ripple handling and long-term stability at elevated temperatures are required.

Key value propositions include high-voltage capability in a compact screw-terminal can, robust ripple-current performance at both low and high frequencies, and a 5000-hour endurance at 105°C for demanding industrial deployments.

Key Features

• High Voltage, High Capacitance — 2700 µF capacitance rated at 500 V DC, supporting high-voltage DC bus applications.
• Screw Terminal Package — Radial can with screw terminals for secure, low-impedance connections in industrial assemblies.
• High Ripple Current Capacity — 9.6 A at 120 Hz (low frequency) and 13.44 A at 10 kHz (high frequency) to handle sustained AC ripple and high-frequency switching currents.
• Thermal Endurance — Rated for operation from −40°C to +105°C with a load life specification of 5000 hours at 105°C under rated ripple conditions.
• Loss and Leakage Characteristics — Specified tan δ of 0.2 (measurement conditions per product datasheet) and measured leakage current of 3480 µA.
• Compact High-Voltage Form Factor — φ63.5 × 135 mm can size offers a smaller high-voltage option within the series for space-constrained designs.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.
• Mass Production Availability — Product is in mass production, suitable for volume deployment.

Typical Applications

• Industrial Power Supplies — Suited for use in industrial power supplies serving inverter circuitry, providing bulk energy storage and smoothing on DC buses.
• AC Servomotor Inverters — Designed for high-frequency regenerative voltage in AC servomotor and general inverter systems where frequent charge–discharge cycles occur.
• High-Speed Charge–Discharge Circuits — Capable of coping with loading from high-speed charge–discharge operations in power-conversion equipment.
• General Purpose Power Electronics — Applicable where a high-voltage, high-capacitance, screw-terminal electrolytic solution is required for robust DC energy storage.

Unique Advantages

• High-voltage capability: 500 V rating enables use directly on elevated DC bus voltages without additional series stacking.
• Strong ripple handling: High specified ripple currents at both 120 Hz and 10 kHz support low-frequency smoothing and high-frequency switching workloads.
• Designed for elevated-temperature endurance: 5000-hour life at 105°C under rated ripple ensures sustained performance in hot industrial environments.
• Secure screw-terminal connectivity: Screw terminals provide robust mechanical and electrical attachment for heavy-current power circuits.
• Compact high-voltage form: φ63.5 × 135 mm size offers a balance of capacitance and footprint for space-conscious power designs.
• Regulatory compliance: RoHS compliance supports integration into equipment requiring restricted-substance adherence.
