LQR2G222MSEFBN

The LQR2G222MSEFBN is a screw-terminal aluminum electrolytic capacitor designed for power electronics applications that require high-voltage bulk energy storage and robust ripple handling. It is a radial can, screw-terminal type with 2,200 µF capacitance rated at 400 V and ±20% tolerance.

Suited to industrial power-conversion environments, this capacitor is specified for high-frequency regenerative voltage use in AC servomotors and general inverters, operation in voltage-fluctuating equipment, and rectifier circuits such as voltage doublers. It combines high-voltage capability with endurance and measurable low-frequency and high-frequency ripple performance.

Key Features

• High capacitance and voltage rating — 2.2 mF (2,200 µF) at 400 V for bulk energy storage in power conversion and filtering.
• Tolerance and loss characteristics — ±20% capacitance tolerance with tanδ (dissipation factor) of 0.15 (measurement context: 120 Hz, 20°C).
• Endurance at elevated temperature — Rated for 5,000 hours at 85°C under specified conditions.
• Ripple handling — Ripple current capability of 10.4 A at 120 Hz and 14.56 A at 10 kHz supports both low- and high-frequency ripple environments.
• Low ESR — Equivalent series resistance of 150 mΩ at 120 Hz to reduce heating and improve efficiency in high-current applications.
• Screw terminal mounting — Radial can with screw terminals (M5 nominal bolt for φ51 body) for secure, low-inductance connections and easy field serviceability.
• Operating temperature range — −25°C to +85°C to cover common industrial ambient conditions.
• Physical and packaging — φ51 × 110 mm can (L: 11 cm × D: 5.1 cm) supplied in cardboard packing; mass-production status.
• RoHS compliant — Conforms with RoHS directive requirements.
• Series-level suitability — Designed for 85°C high-speed charge–discharge duty and recommended for use in equipment exposed to fluctuating voltages.

Typical Applications

• Industrial motor drives — Bulk DC link and regenerative energy buffering for AC servomotors and inverter systems.
• Inverters and converters — DC link smoothing and ripple suppression in general inverter and power-conversion circuits.
• Rectifier/voltage-doubler circuits — Charge storage and filtering in rectifier topologies and voltage-doubler applications.
• Voltage-fluctuating equipment — Energy buffering where input or load voltages are subject to rapid changes or transient events.

Unique Advantages

• Capacitance at high voltage: 2,200 µF at 400 V provides substantial bulk energy capacity for DC link and filtering tasks.
• Measured ripple capability: Rated ripple currents at 120 Hz and 10 kHz allow designers to quantify thermal and lifetime impacts for both low- and high-frequency ripple environments.
• Proven endurance: 5,000-hour endurance rating at 85°C supports long-term operation in industrial temperature conditions.
• Reduced losses and heating: 150 mΩ ESR at 120 Hz helps minimize power dissipation under load, improving efficiency and thermal management.
• Robust mechanical termination: Screw terminals enable secure electrical connections and straightforward installation or service in panel- or chassis-mounted designs.
• Regulatory compliance: RoHS compliance supports use in assemblies requiring restricted-substance adherence.
