LQR2V562MSEHBN

The LQR2V562MSEHBN is a large-can, screw-terminal aluminum electrolytic capacitor from Nichicon's LQR series, rated at 5600 µF and 350 V. It is designed for high-speed charge–discharge and high-frequency regenerative applications, providing robust energy buffering in industrial power electronics.

Targeted use cases include inverter and drive systems, equipment exposed to fluctuating voltages, and rectifier circuits such as voltage doublers. Key attributes include high ripple-current capability, a long 5000-hour endurance at 85°C, and a wide operating temperature range of −25°C to +85°C.

Key Features

• Capacitance & Voltage: 5600 µF nominal capacitance with a rated voltage of 350 V and a tolerance of −20% to +20%.
• High ripple-current handling: Low-frequency ripple current of 19.7 A at 120 Hz and high-frequency ripple current of 27.58 A at 10 kHz, enabling effective suppression of voltage ripple in power circuits.
• Screw-terminal mounting & package: Radial can with screw terminals for secure, low-impedance connections suited to heavy-current installations.
• Endurance and temperature performance: Specified for 5000 hours at 85°C; operational temperature range from −25°C to +85°C.
• Loss and leakage characteristics: Tangent of loss angle (tan δ) of 0.15 measured at 20°C, 120 Hz, and leakage current specified at 4200 µA.
• Physical size & packaging: Large-can dimensions: φ76.2 × 110 mm (diameter × length). Supplied in cardboard packing and currently in mass production.
• Regulatory status: RoHS compliant.
• Designed for demanding charge–discharge: Built for high-speed charge–discharge behavior and regenerative voltage applications as described in the LQR series documentation.

Typical Applications

• Industrial drives and inverters: Provides bulk energy storage and smoothing for general inverters and AC servomotor regenerative circuits where high-frequency charge–discharge capability is required.
• Voltage-doubler and rectifier circuits: Serves as the main energy reservoir in rectifier and voltage-doubler topologies, improving voltage stability under load.
• Equipment in fluctuating-voltage environments: Mitigates transient and sustained voltage fluctuations thanks to high ripple-current tolerance and robust endurance at elevated temperature.

Unique Advantages

• High energy storage at elevated voltage: 5600 µF at 350 V provides substantial stored energy for power conversion and buffering needs.
• High ripple-current capability: 19.7 A (120 Hz) and 27.58 A (10 kHz) ratings reduce heating and improve reliability under continuous ripple loading.
• Long endurance at 85°C: Qualified for 5000 hours at 85°C, offering predictable lifetime performance in thermally demanding environments.
• Screw-terminal mechanical robustness: Screw terminals provide secure, low-impedance connections for high-current assemblies and simplify installation and maintenance.
• Measured dissipation and leakage: Specified tan δ and leakage current values facilitate thermal and loss budgeting during design and validation.
• RoHS compliance and production readiness: Environmentally compliant and available in mass production with cardboard packing for standard handling.
