LQR2W222MSEFBN

The LQR2W222MSEFBN is a screw-terminal aluminum electrolytic capacitor designed for high-speed charge–discharge operation. It provides 2.2 mF (2200 µF) capacitance at a 450 V rating and is optimized for demanding power-electronics environments.

Typical use cases include high-frequency regenerative voltage for AC servomotors, general inverters, equipment operating in voltage-fluctuating environments, and rectifier circuits such as voltage doublers. The part is RoHS compliant and built for robust, high-current power applications.

Key Features

• High Voltage Rating: 450 V rated voltage suitable for medium- to high-voltage power systems.
• Large Capacitance: 2.2 mF (2200 µF) with ±20% tolerance for bulk energy storage and smoothing in inverter and regenerative circuits.
• High-Speed Charge–Discharge: Engineered for 85°C high-speed charge–discharge applications, including frequent regenerative events.
• High Ripple Current Capability: Supports 8.7 A at 120 Hz and 12.18 A at 10 kHz to handle both low- and high-frequency ripple in power systems.
• Endurance and Lifetime: Rated for 5000 hours at 85°C under rated conditions; endurance under repeated charge–discharge (20 million cycles at ΔV = rated × 0.3, 3 Hz) is specified in the datasheet.
• Operating Temperature Range: −25°C to +85°C for operation across a wide range of ambient conditions.
• Screw Terminal Mounting: Radial can with screw terminals for secure, high-current connections and simplified installation in power assemblies.
• Polarized Design: Polarized aluminum electrolytic capacitor for DC link and rectifier applications.

Typical Applications

• AC Servomotor Regeneration: Energy buffering and smoothing for high-frequency regenerative voltage in servo drive systems.
• Inverters and Motor Drives: Bulk storage and ripple suppression in general inverter circuits and motor control power stages.
• Voltage-Doubler Rectifiers: Suitable for rectifier circuits and voltage-doubler arrangements where high DC voltage and robust charge handling are required.
• Equipment in Fluctuating Voltage Areas: Provides stable energy storage and discharge behavior where line voltage varies frequently.

Unique Advantages

• High energy density at elevated voltage: 2.2 mF at 450 V delivers significant stored energy for DC-link and regenerative needs without complex multi-component solutions.
• Designed for high-frequency ripple: Specified ripple current at both 120 Hz and 10 kHz supports applications spanning mains-frequency and switching-frequency disturbances.
• Robust screw-terminal packaging: Screw terminals and radial can body enable reliable, low-impedance connections for high-current installations.
• Long-term endurance: 5000-hour rating at 85°C and defined charge–discharge endurance provide predictable life for continuous-duty power electronics.
• Wide operating range: −25°C to +85°C operation covers a broad set of industrial environments where temperature and voltage vary.
