LQR2V272MSEG

The LQR2V272MSEG is an aluminum electrolytic capacitor in a screw-terminal radial can designed for high-speed charge–discharge and high-voltage power applications. It provides 2.7 mF capacitance at a 350 V rated voltage with polarized construction and ±20% tolerance.

Engineered for use in power-conversion equipment, this part is suited for high-frequency regenerative voltage in AC servomotors and general inverters, equipment operating in voltage-fluctuating environments, and rectifier circuits such as voltage doublers. The component is RoHS compliant.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) nominal capacitance with a 350 V rated voltage and ±20% tolerance.
• High-speed charge–discharge — Series specification calls out 85°C high-speed charge–discharge capability, making the part appropriate for rapid energy transfer in regenerative and inverter circuits.
• Ripple current handling — Rated ripple current of 10.6 A at 120 Hz and 14.84 A at 10 kHz, supporting high-current AC and switching environments.
• Temperature and lifetime — Operating temperature range −25°C to +85°C with an expected endurance of 5000 hours at 85°C under DC bias plus rated ripple current.
• Endurance and charge–discharge durability — Meets series endurance criteria after DC bias plus ripple for 5000 hours and endures charge–discharge behavior testing (20 million cycles, ΔV = rated × 0.3 at 3 Hz) per the datasheet.
• Leakage and stability — Leakage current specification from the series: after 5 minutes at rated voltage leakage is ≤ 3√V μA or 5 mA (whichever is smaller); impedance stability at low temperature is specified (Z(−25°C)/Z(+20°C) ≤ 8).
• Package and mounting — Radial can with screw terminals for secure, high-current connections; physical size L: 8.0 cm × D: 6.35 cm and a maximum seated height of 3.15 inches.
• Terminal hardware — Screw-terminal design with nominal bolt diameter M5 for the φ63.5 mm case size (as defined in the series mechanical specifications).
• Identification — Sleeve marked with white letters on a dark-brown sleeve per series marking convention.
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC servomotor regenerative circuits — Handles high-frequency regenerative voltages and rapid charge–discharge cycles in servo drives.
• General inverters and motor drives — Provides bulk energy storage and ripple filtering in inverter DC buses and power-conversion stages.
• Voltage-doubler rectifier circuits — Suited for rectifier arrangements and designs where voltage fluctuation and high DC bus voltage must be controlled.
• Equipment in fluctuating-voltage environments — Designed for systems exposed to variable supply conditions where stable capacitance and endurance are required.

Unique Advantages

• High energy storage at high voltage — 2.7 mF at 350 V provides significant bulk capacitance for DC bus stabilization in high-voltage power systems.
• Designed for high ripple and switching frequencies — Ripple current ratings at both low and high frequencies enable reliable performance in switching and regenerative applications.
• Robust endurance specification — 5000 hours at 85°C under rated conditions and validated charge–discharge cycling support long-term deployment in demanding power systems.
• Secure screw-terminal connection — Radial can with screw terminals and M5 nominal bolt diameter provides durable, low-resistance connections for high-current paths.
• Wide operating temperature range — −25°C to +85°C operation accommodates a broad set of industrial environments.
• RoHS-compliant — Meets current RoHS requirements for environmental and regulatory conformity.
