LQR2V272MSEGBN

The LQR2V272MSEGBN is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LQR series, featuring 2700 µF capacitance and a 350 V rated voltage. It is a polarized, radial can style capacitor designed for high-speed charge–discharge and high-frequency regenerative voltage handling.

Typical use cases include AC servomotor regenerative circuits, general inverters, equipment operating in voltage-fluctuating environments, and rectifier circuits using voltage doublers. Key value propositions include robust ripple-current capability, endurance at elevated temperature, and a screw-terminal package for secure connections.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) rated at 350 V for bulk energy storage and DC smoothing in high-voltage power circuits.
• High-speed charge–discharge capability — Part of the LQR series engineered for 85°C high speed charge–discharge applications, suitable for regenerative loads.
• Ripple current performance — Rated ripple current of 10.6 A at 120 Hz and 14.84 A at 10 kHz to support demanding AC ripple and switching currents.
• Operating and endurance ratings — Operating temperature range −25°C to +85°C with endurance specified as 5000 hours at 85°C under D.C. bias plus rated ripple current.
• Leakage current specification — After 5 minutes at rated voltage, leakage current is specified as not more than 3√(V) μA or 5 mA, whichever is smaller (at 20°C).
• Mechanical / Mounting — Screw terminal, radial can package (can with screw terminals) for secure, low-impedance connections in power assemblies.
• Polarized design — Polar capacitor suited for DC applications requiring polarity-aware installation.
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Impedance stability at low temperature — Impedance ratio Z(−25°C)/Z(+20°C) specified as 8, aiding predictable performance in colder environments.

Typical Applications

• AC servomotor regenerative circuits — Handles high-frequency regenerative voltages from motor drives where rapid charge–discharge capability is required.
• General inverters — Provides bulk energy storage and ripple handling for inverter DC-link and power-stage stabilization.
• Voltage-doubler rectifier circuits — Suitable for rectifier circuits using voltage-doubler topologies where high DC voltage ratings and polarization are required.
• Equipment in fluctuating-voltage environments — Designed for systems exposed to variable line conditions that demand robust endurance under bias and ripple stress.

Unique Advantages

• High ripple-current capability: 10.6 A at 120 Hz and 14.84 A at 10 kHz reduce heating and improve performance under heavy AC ripple and switching loads.
• Endurance at elevated temperature: 5000 hours at 85°C under rated conditions provides measurable long-term performance for demanding power applications.
• Screw-terminal package for secure connections: Radial can with screw terminals enables low-resistance, mechanically robust mounting in power assemblies.
• Predictable low-temperature behavior: Specified impedance ratio of Z(−25°C)/Z(+20°C) = 8 supports design margining for colder operating environments.
• Measurable leakage limits: Leakage current capped at 3√(V) μA or 5 mA (whichever is smaller) after 5 minutes at rated voltage provides a defined baseline for system leakage budgeting.
• Regulatory compliance: RoHS compliance supports deployment in regions requiring restricted-substance adherence.
