LQR2G822MSEHBN

The LQR2G822MSEHBN is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LQR series, specified for 400 V operation with 8200 µF capacitance and a rated temperature range of -25 °C to 85 °C. Designed for high-speed charge–discharge and demanding power applications, it is intended for use in AC servomotor regenerative circuits, general inverters, voltage-doubler rectifiers and equipment exposed to fluctuating supply voltages.

This unit combines high capacitance and high-voltage capability with a screw-terminal can package and is RoHS compliant, offering long-term endurance and high ripple-current handling for industrial power systems.

Key Features

• Capacitance & Voltage — 8.2 mF (8200 µF) nominal capacitance at a rated voltage of 400 V, with ±20% tolerance at 120 Hz, 20 °C.
• Package & Mounting — Radial can with screw terminals for secure bolted connections; mounting designed for industrial power assemblies.
• Temperature & Lifetime — Rated operating range from -25 °C to 85 °C and endurance of 5000 hours at 85 °C under DC bias plus rated ripple current.
• Ripple Current Performance — Rated ripple current 28.6 A at 120 Hz and 40.04 A at 10 kHz, enabling robust filtering and energy buffering at both low and high frequencies.
• Equivalent Series Resistance (ESR) — 150 mΩ measured at 120 Hz, supporting high-current pulse and regenerative conditions.
• Charge–Discharge Endurance — Specified to meet performance requirements after 20 million charge–discharge cycles (ΔV = rated voltage × 0.3, 3 Hz cycle) at room temperature.
• Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size — Size dimensions L: 17 cm × D: 7.62 cm for integration planning in power racks and enclosures.

Typical Applications

• Motor drives and servomotors — Energy buffering and handling of high-frequency regenerative voltage in AC servomotor systems.
• Inverter systems — Bulk smoothing and transient absorption in general inverters exposed to fluctuating supply conditions.
• Rectifier and voltage-doubler circuits — Bulk storage for rectifier circuits that use voltage-doubling topologies.
• Industrial power equipment — Filtering and energy storage in machinery and equipment operating in environments with voltage variation.

Unique Advantages

• High-voltage, high-capacitance combination: 8200 µF at 400 V provides substantial bulk energy storage within a single radial screw-terminal package, reducing component count for high-voltage power stages.
• Screw-terminal reliability: Bolted screw terminals enable secure connections for high-current and vibration-prone industrial installations.
• Designed for regenerative and fluctuating voltages: Explicit suitability for high-frequency regenerative voltage and fluctuating-voltage equipment supports inverter and motor-drive topologies.
• Strong ripple-current capability: Rated ripple currents of 28.6 A (120 Hz) and 40.04 A (10 kHz) support both mains-frequency smoothing and high-frequency switching environments.
• Durability under stress: 5000 hours endurance at 85 °C and validated performance after 20 million charge–discharge cycles indicate sustained performance in cyclic power applications.
• Regulatory compliance: RoHS conformity simplifies deployment in regions requiring restricted-substance compliance.
