LQR2G332MSEGBN

The LQR2G332MSEGBN is an aluminum electrolytic capacitor in a screw-terminal radial can designed for high-voltage power applications. It provides 3.3 mF capacitance at 400 V with a polarized construction and is intended for use in systems that require high-frequency regenerative handling and robust ripple current performance.

Typical markets include industrial motor drives and inverter equipment, especially where voltage fluctuations and regenerative energy are present. The component combines high ripple capability, defined endurance, and RoHS compliance for reliable integration into power electronics designs.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) rated at 400 V for high-energy storage in high-voltage power circuits.
• Package & Termination — Screw terminal radial can package for secure, high-current connections in chassis-mounted power modules.
• Ripple Current Performance — Rated ripple current of 13.2 A at 120 Hz and 18.48 A at 10 kHz to support both low- and high-frequency filtering and regenerative currents.
• Equivalent Series Resistance (ESR) — 150 mΩ specified at 120 Hz to help minimize power loss and heating under ripple load.
• Operating Temperature — Designed for −25 °C to +85 °C operation to suit a wide range of industrial environments.
• Endurance — 5000 hours at 85 °C under rated conditions; after endurance testing, capacitance remains within ±20% and leakage and tan δ remain within specified limits.
• Charge–Discharge Durability — Endurance of charge–discharge behavior tested to 20 million cycles (ΔV = rated × 0.3, 3 Hz) with maintained electrical characteristics.
• Leakage Current Limit — After 5 minutes at 20 °C, leakage current is limited to not more than 3√(√V) µA or 5 mA, whichever is smaller, per the datasheet formulation.
• Size — Dimensions: L: 11 cm × D: 6.35 cm for compact high-voltage modules.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC servomotor drives — Handles high-frequency regenerative voltages and energy return paths in servo systems.
• General inverters — Bulk energy storage and ripple filtering in inverter DC link and power conversion stages.
• Voltage-doubler rectifier circuits — Suitable for rectifier circuits including voltage-doubler topologies where stable high-voltage capacitance is required.
• Equipment in fluctuating-voltage environments — Useful where supply voltages vary and robust energy buffering is needed to maintain system stability.

Unique Advantages

• High-voltage energy storage: 400 V rating and 3.3 mF capacitance provide substantial DC-link energy for power conversion and regenerative applications.
• Designed for high ripple loads: Specified ripple currents at both 120 Hz and 10 kHz with low ESR reduce heating and improve thermal stability under continuous ripple stress.
• Proven endurance: 5000-hour endurance at 85 °C and validated charge–discharge cycling (20 million cycles at ΔV = 0.3× rated) support long-term reliability in demanding duty cycles.
• Robust, serviceable connections: Screw terminal format provides secure mechanical and electrical connections for high-current, field-installable assemblies.
• Wide operating range: −25 °C to +85 °C operation and defined impedance behavior at low temperature (Z(−25 °C)/Z(+20 °C) = 8) help maintain performance across typical industrial climates.
• RoHS compliant: Meets current RoHS requirements for regulatory and environmental compatibility.
