LQR2G562MSEHBB

The LQR2G562MSEHBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LQR series, providing 5.6 mF capacitance at a 400 V rating in a radial can with screw terminals. It is built for power electronics that require high-capacitance energy storage and robust charge–discharge performance under fluctuating voltages.

Designed for applications such as regenerative circuits and inverters, this capacitor delivers high ripple-current handling, rated endurance at elevated temperature, and stable electrical characteristics across the specified -25°C to +85°C operating range.

Key Features

• Capacitance & Voltage — 5.6 mF (5600 µF) nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High ripple-current capability — 21.4 A low-frequency ripple current (120 Hz) and 29.96 A high-frequency ripple current (10 kHz) support demanding AC and power-conversion loads.
• Loss factor (tan δ) — Specified tan δ of 0.15 at 20°C and 120 Hz, supporting predictable dissipation characteristics for thermal and performance planning.
• Endurance and reliability — Rated for 5000 hours at 85°C under DC bias plus rated ripple current; charge–discharge endurance validated to 20 million cycles (ΔV = rated × 0.3, 3 Hz) per the series specification.
• Temperature stability — Operating range from -25°C to +85°C with an impedance ratio Z(-25°C)/Z(+20°C) of up to 8 for the 350–450 V range, aiding low-temperature performance assessment.
• Mechanical and mounting — Radial can with screw terminals (φ76.2 mm diameter × 130 mm length); nominal bolt diameter for this diameter size is M5, simplifying busbar or stud connections.
• Leakage current — Specified leakage current value of 4480 µA after application of rated voltage (product data value).
• Compliance & packaging — RoHS compliant and supplied in cardboard packing; product is in mass production.

Typical Applications

• AC servomotor regenerative circuits — Supports high-speed charge–discharge behavior required for regenerative energy capture in servomotor systems.
• General inverters — Provides bulk energy storage and ripple handling for inverter DC-link sections operating under fluctuating voltages.
• Equipment operating in fluctuating-voltage environments — Stabilizes DC bus voltage and absorbs transient energy where input or load voltages vary.
• Rectifier / voltage-doubler circuits — Suitable for rectifier configurations and voltage-doubler topologies requiring high-capacitance smoothing under elevated voltages.

Unique Advantages

• High-energy storage at 400 V: 5600 µF capacitance at a 400 V rating enables substantial energy buffering in compact power stages.
• Robust ripple handling: High ripple current ratings at both low and high frequencies (21.4 A @120 Hz, 29.96 A @10 kHz) reduce temperature rise and extend service life in dynamic power applications.
• Engineered for endurance: 5000-hour life at 85°C under rated conditions and validated charge–discharge endurance support long-term use in high-cycle systems.
• Screw-terminal convenience: M5-capable screw terminals and a φ76.2 mm can diameter simplify secure high-current connections and mechanical mounting.
• Predictable dissipation: Specified tan δ (0.15 at 20°C, 120 Hz) and leakage current figures facilitate thermal and loss budgeting in system design.
• RoHS compliant and production-ready: Meets RoHS requirements and is available in mass production with cardboard packing for handling and storage.
