LNU2H152MSEGBN

The LNU2H152MSEGBN from Nichicon is a screw-terminal, high-voltage aluminum electrolytic capacitor designed for industrial power electronics. It is a 1500 µF (1.5 mF), 500 V polarized capacitor rated for operation from −40 °C to 105 °C and optimized for inverter and regenerative circuits.

This part combines high-voltage capability with a smaller footprint than Nichicon's LNT series, offering long load life and high ripple handling for demanding AC servomotor and general inverter applications.

Key Features

• Screw Terminal Packaging: Radial can with screw terminals for secure, low-resistance connections in power modules and industrial assemblies.
• High Voltage Rating: Rated at 500 V nominal (series rated voltage range up to DC 525 V), supporting inverter and high-voltage bus applications.
• Capacitance & Tolerance: 1.5 mF (1500 µF) with ±20% tolerance (120 Hz, 20 °C) for bulk energy storage and smoothing.
• Wide Temperature Range: Operates from −40 °C to 105 °C, with endurance specified at elevated temperature for industrial environments.
• Long Load Life: 5000 hours at 105 °C under rated ripple current and DC bias, with defined limits for capacitance, tan δ and leakage current after endurance.
• High Ripple & High-Frequency Performance: Ripple current capability of 6.6 A at 120 Hz and 9.24 A at 10 kHz, and designed to cope with high-speed charge–discharge loading and high-frequency regenerative voltages.
• Leakage Current Specification: After 5 minutes' application of rated voltage at 20 °C, leakage current is not more than 3√(C·V) µA or 5 mA, whichever is smaller.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters: Bulk energy storage and DC-link smoothing for general inverter circuitry in industrial power supplies.
• AC Servomotor Drives: Handles high-frequency regenerative voltages and rapid charge–discharge cycles common in servomotor drive systems.
• Power Supply Modules: High-voltage filtering and ripple suppression in industrial power modules and converters.

Unique Advantages

• Higher Voltage in a Smaller Footprint: Series design offers high-voltage capability while being smaller than Nichicon's LNT series, aiding compact power designs.
• Robust High-Temperature Endurance: Specified 5000-hour load life at 105 °C under rated ripple and DC bias, supporting reliable long-term operation in hot environments.
• Designed for High-Speed Cycling: Built to tolerate rapid charge–discharge loading and specified for 50 million charge–discharge cycles at 3 Hz, maintaining key electrical parameters.
• Strong Ripple Current Performance: Clear ripple current ratings at both low (120 Hz) and high (10 kHz) frequencies to support a range of switching and regenerative power topologies.
• Screw-Terminal Reliability: Mechanical and electrical robustness of screw terminals simplifies integration into industrial assemblies and enables secure connections for high-current paths.
• RoHS Compliant: Meets applicable RoHS directives for environmental regulatory requirements.
