LQR2W562MSEGBB

The LQR2W562MSEGBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LQR series designed for high-voltage, high-ripple power applications. It is a polarized radial can with screw terminals, rated 5.6 mF (5600 µF) at 450 V and specified for continuous operation across −25°C to 85°C.

Engineered for industrial power electronics, the LQR series is suited to high-frequency charge–discharge conditions including regenerative voltage on AC servomotors and general inverter equipment, and for use in rectifier/voltage-doubler circuits and other applications experiencing voltage fluctuation.

Key Features

• Capacitance & Voltage — 5.6 mF (5600 µF) nominal capacitance at a rated voltage of 450 V for bulk energy storage in high-voltage systems.
• High ripple capability — Ripple current capability of 19.4 A at 120 Hz and 27.16 A at 10 kHz to support heavy AC ripple and high-frequency charge–discharge cycles.
• Low ESR — Equivalent series resistance of 150 mΩ at 120 Hz for reduced dissipation and improved thermal performance under ripple load.
• Endurance — Specified 5000 hours at 85°C with D.C. bias plus rated ripple current; meets endurance criteria for capacitance, tan δ, and leakage current after the test.
• Charge–discharge robustness — Endurance of charge–discharge behavior: rated for 20 million cycles (ΔV = rated voltage × 0.3, 3 Hz) at room temperature while meeting capacitance, tan δ and leakage requirements.
• Construction & mounting — Radial can with screw terminals (nominal bolt M5) for secure, low-impedance connections in power racks and assemblies.
• Operating range & tolerance — Operates from −25°C to +85°C with capacitance tolerance of ±20% (at 120 Hz, 20°C).
• Leakage current — Specified leakage current value of 4.76 mA (measured condition per product data), supporting predictable standby and hold-up behavior.
• Compliance & packaging — RoHS compliant and available in cardboard packing for mass production.

Typical Applications

• Motor drives & servos — Supports regenerative voltage and high-frequency charge–discharge cycles in AC servomotor and inverter systems.
• Industrial inverters — Bulk smoothing and energy buffering for general inverter platforms operating with fluctuating supply or regenerative loads.
• Rectifier & voltage-doubler circuits — High-voltage capacitance for rectifier stages and voltage-doubler configurations requiring sustained DC hold-up.
• Industrial power supplies — Energy storage and ripple handling in power conversion equipment subject to high ripple currents and variable line conditions.
