LQR2V562MSEGBN

The LQR2V562MSEGBN from Nichicon is a screw-terminal aluminum electrolytic capacitor designed for high-speed charge–discharge environments. It delivers 5600 µF capacitance at a 350 V rated voltage and is intended for applications that require robust energy buffering under fluctuating voltages.

Engineered for industrial power electronics, this capacitor suits high-frequency regenerative voltage systems such as AC servomotors and general inverters, and can be used in rectifier circuits including voltage doubler configurations. It is RoHS compliant and specified for operation from −25°C to 85°C.

Key Features

• Capacitance & Voltage — 5.6 mF (5600 µF) nominal capacitance at a 350 V rated voltage for bulk energy storage and smoothing in power stages.
• Screw Terminal Mounting — Radial can with screw terminals provides secure, low-impedance electrical connections suited to industrial assemblies.
• High-speed Charge–Discharge — Designed for high speed charge-discharge behavior; datasheet endurance includes 20 million charge–discharge cycles under specified test conditions.
• Ripple Current Capability — Rated ripple current: 20.4 A at 120 Hz and 28.56 A at 10 kHz, supporting high-frequency ripple conditions in inverters and regenerative circuits.
• Temperature & Endurance — Operational range −25°C to 85°C with an endurance rating of 5000 hours at 85°C under DC bias plus rated ripple current.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is limited per datasheet formula (≤ 3√(√V) μA or 5 mA, whichever is smaller, at 20°C).
• Polarized — Electrolytic (polar) capacitor; observe polarity in installation. Tolerance ±20% at 120 Hz, 20°C.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC Servomotor Regeneration — Handles high-frequency regenerative voltages and fast charge–discharge cycles found in servo drive systems.
