LNU2H152MTEF

The LNU2H152MTEF is a Nichicon LNU-series aluminum electrolytic capacitor in a screw-terminal (stud bolt) radial can package, featuring 1.5 mF capacitance and a 500 V DC rating. It is designed for industrial power electronics where high-voltage, high-ripple and robust charge-discharge performance are required.

Suited for inverter circuitry and industrial power supplies, this capacitor supports high-frequency regenerative voltages such as those encountered in AC servomotor and general inverter applications. The LNU series provides high-voltage capability with a compact footprint and is RoHS compliant.

Key Features

• Capacitance & Voltage — 1.5 mF nominal capacitance with a 500 V rated DC voltage; capacitance tolerance ±20% (120 Hz, 20°C).
• Package & Mounting — Screw-terminal, radial can design with stud bolt mounting for secure mechanical and electrical connections.
• Temperature Range & Lifetime — Operates from −40°C to +105°C with a rated load life of 5000 hours at 105°C under rated ripple-current conditions.
• High-Frequency/Ripple Performance — Rated ripple current 6.6 A at 120 Hz and 9.24 A at 10 kHz, supporting high-frequency regenerative and inverter environments.
• Endurance & Charge–Discharge Robustness — Series-level endurance testing includes charge–discharge cycling (specified in the datasheet at 50 million cycles) and long-term DC bias plus ripple endurance at 105°C for 5000 hours.
• Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact High-Voltage Design — LNU series provides high-voltage capability in a smaller size compared with previous LNT series designs (series characteristic from datasheet).

Typical Applications

• Industrial Inverters — Bulk and DC-link filtering in inverter power stages where high DC voltage and ripple handling are required.
• AC Servo Drives — Supports high-frequency regenerative voltage and frequent charge–discharge events common in servo motor control.
• Industrial Power Supplies — Energy storage and smoothing in high-voltage industrial power systems and converter supplies.
• Regenerative Braking Systems — Energy buffering for systems that return energy to the DC bus, benefiting from the capacitor’s high ripple-current capability.

Unique Advantages

• High-voltage capability — 500 V rating (series rated up to 525 V) enables use in high-voltage DC-link and converter topologies.
• Designed for high ripple and high-frequency use — Specified ripple currents at 120 Hz and 10 kHz make it suitable for demanding inverter and regenerative environments.
• Long high-temperature load life — 5000 hours at 105°C under rated ripple conditions supports reliable operation in elevated-temperature industrial settings.
• Robust charge–discharge endurance — Series-level charge–discharge endurance testing (datasheet specifies 50 million cycles) reduces risk of premature degradation in frequent-cycling applications.
• Secure mechanical and electrical termination — Screw-terminal/stud bolt mounting provides reliable connections for high-current and high-vibration installations.
• RoHS compliant — Meets EU RoHS requirements for restricted substances.
