LQR2G222MSEF

The LQR2G222MSEF is a screw‑terminal aluminum electrolytic capacitor designed for high‑speed charge–discharge applications. It delivers 2200 µF at a 400 V rating in a radial can with screw terminals for robust electrical and mechanical connection.

Engineered for power electronics, this capacitor suits high‑frequency regenerative voltage systems such as AC servomotors and general inverters, equipment operating in voltage‑fluctuating environments, and rectifier circuits including voltage doubler topologies.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High‑speed charge–discharge behavior — Series specification includes endurance under repeated charge–discharge cycling (20 million cycles at ΔV = rated × 0.3, 3 Hz) to preserve capacitance and leakage performance.
• Ripple handling and ESR — Low equivalent series resistance of 150 mΩ at 120 Hz combined with rated ripple currents of 10.4 A (120 Hz) and 14.56 A (10 kHz) for effective smoothing in high‑ripple applications.
• Endurance at elevated temperature — Demonstrated endurance of 5000 hours at 85°C under D.C. bias plus rated ripple current while meeting capacitance, tan δ and leakage requirements.
• Robust screw‑terminal package — Radial can with screw terminals for secure bolted connections suitable for power modules and serviceable installations.
• Operating range — Specified for −25°C to +85°C operation, enabling use across common industrial temperature environments.
• Environmental compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Inverters and motor drives — Energy buffering and smoothing for AC servomotor drives and general inverters handling regenerative currents.
• Regenerative power circuits — High‑frequency regenerative voltage support where fast charge/discharge and high ripple capability are required.
• Rectifier and voltage doubler circuits — Bulk storage and filtering in rectifier stages including voltage doubler configurations.
• Equipment in voltage‑fluctuating areas — Stabilization and transient energy absorption for systems exposed to variable supply conditions.
• General power filtering — Bulk smoothing and decoupling in industrial power electronics and power supply modules.

Unique Advantages

• Rated for high DC voltages: 400 V rating supports medium‑voltage power rails without series arrangements.
• High ripple capability with low ESR: 150 mΩ ESR and specified ripple currents at 120 Hz and 10 kHz improve heat handling and reduce loss under AC stress.
• Proven endurance: 5000 hours at 85°C plus validated charge–discharge endurance preserves electrical characteristics over extended service life.
• Screw‑terminal connectivity: Bolted terminals provide secure current paths and simplify installation and maintenance in power assemblies.
• Wide industrial temperature range: −25°C to +85°C suitability covers typical industrial operating environments.
• RoHS compliant: Meets current RoHS requirements for environmentally regulated designs.
