LQR2G472MSEGBN

The LQR2G472MSEGBN is a Nichicon screw terminal aluminum electrolytic capacitor providing 4700 µF capacitance at a 400 V rating. It is a screw-terminal, radial can design sized φ63.5 × 150 mm and intended for high-speed charge–discharge and power-management use in industrial power electronics.

Designed for applications such as AC servomotor regenerative circuits, general inverters and voltage-doubler rectifiers, the capacitor combines high capacitance, substantial ripple-current capability and a rated lifetime of 5000 hours at 85°C to support demanding power and energy-storage requirements.

Key Features

• Capacitance & Voltage — 4700 µF nominal capacitance rated for 400 V DC, with tolerance ±20% (measured at 120 Hz, 20°C).
• Screw Terminal Mounting — Robust radial can with screw terminals (M5 bolt nominal) for secure high-current connections in industrial assemblies.
• High Ripple Current Capability — Low-frequency ripple current 18.7 A at 120 Hz and high-frequency ripple current 26.18 A at 100 kHz for energy buffering and smoothing under heavy load.
• Thermal & Lifetime Performance — Rated for operation from −25°C to +85°C with an endurance life of 5000 hours at 85°C under rated DC bias plus ripple current.
• Charge–Discharge Endurance — Specified to meet performance requirements after 20 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz) at room temperature.
• Loss and Leakage — Tangent of loss angle (tan δ) 0.15 measured at 20°C, 120 Hz; leakage current specified at 4110 µA.
• RoHS Compliance — Conforms to RoHS directive requirements for restricted substances.
• Package & Handling — Physical dimension φ63.5 × 150 mm (L × D approx. 15 × 6.35 cm) and supplied in cardboard packing for safe transport and handling.

Typical Applications

• AC Servomotor Regeneration — Energy buffering and smoothing for high-frequency regenerative voltages in servo drives and motion-control systems.
• General Inverters — Bulk energy storage and ripple suppression in inverter DC-link circuits where high ripple current capability is required.
• Voltage-Doubler Rectifiers — Suitable for rectifier stages and voltage-doubler circuits that need large capacitance at high voltage.
• Industrial Power Electronics — Use in equipment exposed to fluctuating voltages where robust charge–discharge endurance and thermal stability are important.

Unique Advantages

• High energy density for 400 V systems: 4700 µF at 400 V provides substantial DC-link or smoothing capacitance in a single component, reducing board-level complexity.
• Designed for heavy ripple loads: Specified ripple currents of 18.7 A (120 Hz) and 26.18 A (100 kHz) support demanding power-conversion and regenerative applications.
• Long operational life at elevated temperature: 5000 hours at 85°C under rated conditions gives predictable durability for industrial environments.
• Robust mechanical termination: Screw-terminal, radial can packaging enables secure connections for high-current paths in power assemblies.
• Proven charge–discharge endurance: Compliance with 20 million charge–discharge cycles at defined conditions supports frequent energy cycling use cases.
• Regulatory compliance: RoHS conformity supports deployments where restricted-substance compliance is required.
