LQR2G822MSEJBB

The LQR2G822MSEJBB is an aluminum electrolytic, screw-terminal capacitor from Nichicon’s LQR series, specified at 8.2 mF (8200 µF) and 400 V. It is a radial can with screw terminals engineered for high-frequency charge–discharge conditions and DC-link energy storage in power electronics.

Designed for applications that experience voltage fluctuation and regenerative voltages, this part targets inverters, AC servomotor drives, and rectifier circuits including voltage-doubler topologies, offering robust ripple handling and proven endurance at elevated temperatures.

Key Features

• Capacitance & Voltage — 8.2 mF (8200 µF) rated at 400 V for substantial energy storage in DC-link and filtering applications.
• Screw-Terminal Package — Radial can with screw terminals for secure, low-inductance connections in high-current installations.
• Temperature Range & Endurance — Operates from −25 °C to +85 °C with an endurance rating of 5000 hours at 85 °C under D.C. bias plus rated ripple current.
• High Ripple Capability — Rated ripple current of 27.8 A at 120 Hz and 38.92 A at 10 kHz to support both low- and high-frequency power pulses.
• Charge–Discharge Durability — Series specification includes endurance for repeated charge–discharge cyclings (20 million cycles at ΔV = rated × 0.3, 3 Hz) with defined recovery criteria.
• Performance Stability — Endurance limits: capacitance change within ±20%, tan δ within specified bounds, and leakage current returning to initial specified values after endurance testing.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• AC Servomotor Drives — Handles high-frequency regenerative voltages and energy recovery in motion-control DC-link circuits.
• General Inverters — Provides bulk energy storage and ripple filtering for inverter DC-link stages operating with fluctuating line conditions.
• Voltage-Doubler Rectifiers — Suited for rectifier circuits where the capacitor must withstand voltage-doubled conditions and transient stress.
• Equipment in Fluctuating-Voltage Areas — Built for installations exposed to variable supply conditions where robust voltage endurance and ripple tolerance are required.

Unique Advantages

• High energy density at system voltage — 8.2 mF at 400 V stores significant DC-link energy for smoothing and transient support.
• Secure, low-inductance connections — Screw terminal mounting ensures reliable electrical and mechanical connection for high-current systems.
• Dual-frequency ripple performance — Specified ripple ratings at 120 Hz and 10 kHz address both mains-frequency and high-frequency switching environments.
• Proven thermal endurance — Rated for 5000 hours at 85 °C under rated conditions, supporting longevity in elevated-temperature enclosures.
• Charge–discharge robustness — Series-tested for tens of millions of charge–discharge cycles to maintain capacitance, dissipation factor, and leakage within specified limits.
• Standards compliance — RoHS conformity supports regulatory requirements for modern equipment designs.
