LNU2H152MSEF

The LNU2H152MSEF is a high-voltage aluminum electrolytic capacitor in a screw-terminal radial can, rated at 1500 µF and 500 V with a 105°C operating temperature. Designed for industrial power electronics, it supports inverter circuitry, high-frequency regenerative voltage and high-speed charge–discharge loading found in servo drives and general inverters.

Its design emphasizes high-voltage capability in a smaller package (relative to the LNT series), long high-temperature life, and robust ripple and charge–discharge endurance for demanding industrial applications.

Key Features

• Capacitance & Voltage — Nominal 1.5 mF (1500 µF) 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 and a load life of 5000 hours at 105°C under rated ripple conditions.
• Ripple Current Performance — Capable of 6.6 A ripple at 120 Hz and 9.24 A at 10 kHz, supporting both low- and high-frequency ripple environments.
• Screw-terminal Radial Can — Robust screw terminal package for secure connections; terminal hardware and bracket details are provided in the series drawing (nominal bolt M5 specified in series documentation).
• Charge–Discharge Durability — Designed to cope with high-speed charge–discharge loading and verified endurance for repeated charge–discharge cycles per series specifications.
• Series-level Voltage Range and Compliance — Series rated voltage range up to DC 525 V and RoHS compliant (2011/65/EU, (EU)2015/863).
• Practical Size — Compact radial can dimensions (L: 13.5 × D: 5.1 cm) suitable for space-conscious industrial designs.

Typical Applications

• Industrial Inverters: Energy storage and smoothing in inverter power supplies for motor drives and industrial power conversion.
• AC Servomotor Regenerative Circuits: Handling high-frequency regenerative voltage and energy recovery in servo drive systems.
• High-speed Charge–Discharge Systems: Applications requiring frequent or rapid charge–discharge cycles, where endurance and stable capacitance at elevated temperatures are critical.

Unique Advantages

• High-voltage capability in a reduced footprint: 500 V rating with series designs up to DC 525 V while offering smaller sizing versus comparable models in the LNT family.
• Long life at elevated temperature: 5000-hour load life at 105°C supports reliable operation in harsh industrial thermal environments.
• Wide frequency ripple handling: Specified ripple current at both 120 Hz and 10 kHz enables use across a range of power-conversion topologies and switching frequencies.
• Secure, serviceable connections: Screw-terminal radial can and M5 terminal provisions simplify installation and maintenance in field or bench environments.
• Designed for charge–discharge endurance: Engineered to withstand high-speed charge–discharge loading common in regenerative and switching applications.
• Regulatory compliance: RoHS compliant to support placement in regulated industrial equipment.
