LNUN7562MSEJBN

The LNUN7562MSEJBN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNU series designed for high-voltage industrial power electronics. It delivers 5.6 mF capacitance at a DC rating of 525 V in a radial can with screw terminals, optimized for inverter circuitry and high-frequency regenerative environments.

Engineered for sustained operation in demanding thermal and ripple-current conditions, this capacitor supports high-speed charge–discharge loading and long-term endurance up to 105°C, making it suitable for industrial power supplies, inverter systems and AC servomotor applications.

Key Features

• High Voltage Rating — Rated up to DC 525 V to support inverter and high-voltage power-supply designs.
• Large Capacitance — 5.6 mF (5,600 μF) nominal capacitance with ±20% tolerance for bulk energy storage and smoothing.
• Screw Terminal, Radial Can Package — Robust screw-terminal connections and radial-can packaging for secure, low-resistance mounting in industrial assemblies.
• Wide Operating Temperature — Specified for –40°C to +105°C to meet demanding thermal environments.
• High Ripple Current Capability — Rated ripple current of 17.5 A at 120 Hz and 24.5 A at 10 kHz to handle heavy AC ripple and high-frequency loading.
• Long Life at Elevated Temperature — Load-life rating of 5,000 hours under rated ripple-current application at 105°C.
• Leakage Current Specification — After 5 minutes’ application of rated voltage, leakage is limited to not more than 3√(C·V) μA or 5 mA, whichever is smaller (measured at 20°C).
• Insulation and Voltage Withstand — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2,500 V for 1 minute between terminal and bracket.
• Charge–Discharge Endurance — Meets endurance requirements after extensive charge–discharge cycling (tested for 50 million cycles, cycle 3 Hz).
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU,(EU)2015/863).
• Compact Size — Smaller footprint within the LNU series while maintaining high-voltage capability; size dimension L: 15.5 × D: 9 cm (radial can).

Typical Applications

• Industrial Inverters — Bulk energy storage and ripple smoothing in inverter power supplies where high DC voltage and reliable ripple handling are required.
• AC Servomotor Drives — Supports high-frequency regenerative voltage and high-speed charge–discharge cycling common in servo drive systems.
• Power Supply Filtering — Energy buffering and smoothing in industrial power-supply rails subjected to elevated temperature and high ripple currents.
