LNU2G562MSEHBB

The LNU2G562MSEHBB is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNU series, offering 5.6 mF capacitance at a 400 V rating. Designed for industrial power electronics, it targets DC link and inverter applications that require high-voltage capability, high ripple handling and long-term operation at elevated temperatures.

As a high-voltage, compact screw-terminal can, this capacitor supports high-speed charge–discharge loading and high-frequency regenerative voltages common in AC servomotor drives and general inverters, while meeting RoHS requirements.

Key Features

• Electrical Performance — 5.6 mF (5600 µF) capacitance with ±20% tolerance, polarized construction, and a rated voltage of 400 V (series rated up to DC525 V).
• High Ripple Capability — Specified ripple current: 17.1 A at 120 Hz and 23.94 A at 10 kHz, enabling robust AC ripple handling in power conversion and regenerative circuits.
• Thermal and Life Performance — Operating range –40 °C to +105 °C with a load life of 5000 hours at 105 °C under rated ripple current and DC bias; designed for sustained high-temperature service.
• Mechanical / Package — Screw terminal radial can package for secure bus connections; package dimensions L: 10.5 cm × D: 7.62 cm with a maximum seated height of 4.134 inches.
• Reliability and Testability — Insulation resistance more than 100 MΩ at DC 500 V (terminal to bracket) and voltage proof of AC 2500 V for 1 minute; leakage-current specification of ≤ 3√(C·V) µA or 5 mA after 5 minutes at 20 °C.
• Endurance and Charge–Discharge Durability — Endurance validated after D.C. bias plus rated ripple current for 5000 hours at 105 °C; designed to meet specified limits for capacitance, tan δ and leakage current after recovery to 20 °C. Also tested for charge–discharge endurance (50 million cycles under specified conditions).
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — DC link and energy storage in inverter circuitry for motor drives and industrial power supplies where high-voltage, high-ripple capacitors are required.
• AC Servomotor Drives — Handling high-frequency regenerative voltages and rapid charge–discharge events in servo systems.
• Regenerative Braking Circuits — Energy buffering for high-speed charge–discharge cycles in regenerative power circuits.
• High-Power DC Power Supplies — Bulk smoothing and ripple suppression in industrial DC supply designs operating at elevated temperatures.

Unique Advantages

• High-Voltage Capability: Rated at 400 V with series options to DC525 V, enabling use in higher-voltage power electronics designs without multiple smaller capacitors in series.
• High Ripple Handling: Explicit ripple current ratings at both low and high frequencies (120 Hz and 10 kHz) provide designers with quantifiable performance for thermal and lifetime calculations.
• Long-Term Elevated-Temperature Operation: 5000-hour load life at 105 °C under rated ripple and DC bias supports reliability in thermally demanding industrial environments.
• Screw-Terminal Robustness: Screw terminal radial can package simplifies secure, low-impedance bus connections for high-current systems.
• Tested Durability: Insulation resistance, voltage proof and extensive charge–discharge endurance testing deliver measurable assurance of long-term performance under realistic stress conditions.
• RoHS Compliance: Meets current RoHS directives, supporting regulatory requirements for industrial equipment.
