LQR2G332MSEGBB

The LQR2G332MSEGBB from Nichicon is an aluminum electrolytic capacitor in a screw-terminal radial can package, rated at 3.3 mF (3300 µF) and 400 V. It is built for general-purpose power-electronics use where high-voltage filtering, regenerative voltage handling and robust screw-terminal connections are required.

Designed for industrial power systems, this capacitor supports high-frequency charge–discharge conditions and is suited for applications such as AC servomotors, general inverters, voltage-doubler rectifiers and equipment operating in fluctuating-voltage environments. It is RoHS compliant and specified for operation from −25 °C to +85 °C.

Key Features

• High Voltage Rating — 400 V rated voltage suitable for medium- and high-voltage power-electronics circuits requiring bulk energy storage and filtering.
• Large Capacitance — 3.3 mF (3300 µF) capacitance with ±20% tolerance for smoothing and energy buffering in inverter and regenerative circuits.
• Screw Terminal Mounting — Radial can with screw terminals for secure, low-inductance connection and easy installation in industrial assemblies.
• Wide Operating Temperature — Specified operation from −25 °C to +85 °C for use across typical industrial ambient conditions.
• High Ripple Handling — Rated ripple current of 13.2 A at 120 Hz and 18.48 A at 10 kHz to support AC and high-frequency ripple environments.
• Long Endurance — Designed to meet endurance requirements of 5000 hours at 85 °C under D.C. bias plus rated ripple current, and endurance under repeated charge–discharge cycling per datasheet conditions.
• Polarized Construction — Polarized capacitor suitable for DC-oriented power circuits and rectifier stages.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC servomotor drives — Bulk energy buffering and handling of regenerative voltages in motor control systems.
• General inverters — DC link and smoothing applications in power conversion equipment that experience voltage fluctuation and high-frequency ripple.
• Voltage-doubler rectifier circuits — Energy storage and smoothing in rectifier configurations including voltage-doubler topologies.
• Industrial equipment in fluctuating-voltage environments — Robust polarized capacitance for systems exposed to variable supply conditions.

Unique Advantages

• High energy capacity at 400 V: 3.3 mF capacitance provides substantial charge storage for smoothing and regenerative functions without requiring parallel arrays.
• Screw-terminal reliability: Secure mechanical and electrical connections reduce installation time and contact issues in heavy-current industrial systems.
• High-frequency ripple capability: Specified ripple currents at both 120 Hz (13.2 A) and 10 kHz (18.48 A) let designers size the capacitor for both mains-frequency and high-frequency switching applications.
• Endurance and cycle robustness: Meets 5000-hour endurance at 85 °C under rated conditions and is specified for 20 million charge–discharge cycles per datasheet endurance criteria, supporting long service life in demanding duty cycles.
• Wide temperature range: −25 °C to +85 °C operation allows deployment across a broad set of industrial ambient conditions.
• Regulatory compliance: RoHS compliance supports use in regions and products that require restricted-substance conformity.
