LQR2V272MSEFBN

The LQR2V272MSEFBN from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LQR series, rated at 2.7 mF (2700 µF) and 350 V. It is designed for high-speed charge–discharge and high-frequency regenerative voltage handling in industrial power equipment.

Targeted at inverter and motor-drive environments, this capacitor provides robust performance for equipment exposed to fluctuating voltages and for rectifier circuits such as voltage doublers. It is RoHS compliant and built for screw-terminal mounting in radial can packages.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance with a 350 V rated voltage and ±20% tolerance.
• Screw Terminal Package — Radial, can-style body with screw terminals for secure, low-impedance power connections and easy field wiring.
• High-speed Charge–Discharge — Designed for high-frequency regenerative voltage use in AC servomotor and general inverter applications; datasheet specifies charge–discharge endurance testing (20 million cycles, ΔV = rated voltage × 0.3, 3 Hz).
• Wide Operating Temperature — Rated for operation from −25 °C to +85 °C suitable for many industrial environments.
• Long Endurance — Endurance rating of 5000 hours at 85 °C with DC bias plus rated ripple current applied; capacitance change, dissipation factor, and leakage current meet specified limits after test.
• High Ripple Current Capability — Specified ripple current of 10.8 A at 120 Hz and 15.12 A at 10 kHz to support high-frequency power circuits.
• Polarized Design — Polarized aluminum electrolytic construction for DC bus and energy-storage roles.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• Motor Drives and AC Servomotors — Handles high-frequency regenerative voltage in drive systems and supports energy recovery and smoothing on the DC bus.
• General Inverters — Suitable for inverter DC-link use where voltage can fluctuate and high ripple currents are present.
• Rectifier and Voltage Doubler Circuits — Well suited to rectifier circuits including voltage doublers, providing bulk energy storage and filtering.
• Industrial Power Equipment — Designed for equipment operating in voltage-fluctuating areas where durable, high-voltage bulk capacitance is required.
