LQR2W272MSEF

The LQR2W272MSEF from Nichicon is an aluminum electrolytic, screw‑terminal capacitor rated at 2700 µF and 450 V with an operating temperature range of -25 °C to +85 °C. It is a screw‑terminal, radial can design engineered for high‑speed charge–discharge and applications with high frequency regenerative voltages.

Typical use cases include AC servomotor drives, general inverters, equipment operating in voltage‑fluctuating environments, and rectifier circuits such as voltage doublers. The part is RoHS compliant and is designed for sustained performance under DC bias and ripple stress.

Key Features

• Capacitance & Voltage — 2700 µF nominal capacitance at a rated voltage of 450 V, with a capacitance tolerance of ±20% (120 Hz, 20 °C).
• High‑speed charge–discharge — Screw terminal, radial can construction optimized for high frequency regenerative voltage applications.
• Ripple current performance — Rated ripple currents of 10.2 A at 120 Hz and 14.28 A at 10 kHz to support high dynamic loading in inverter and drive circuits.
• Temperature & Endurance — Operates from -25 °C to +85 °C; endurance validated to 5000 hours at 85 °C under DC 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).
• Charge–discharge durability — Endurance of charge–discharge behavior verified for 20 million cycles (ΔV = rated × 0.3, 3 Hz) at room temperature.
• Package & Mounting — Radial can with screw terminals for secure mechanical and electrical connection; package dimensions L: 15 cm × D: 5.1 cm.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC servo drives — Handles high frequency regenerative voltages and rapid charge–discharge cycles common in motion control systems.
• General inverters — Supports DC bus smoothing and transient energy buffering in industrial inverter designs.
• Voltage‑doubler rectifier circuits — Suited for rectifier stages where voltage doubling and fluctuating input require robust capacitance and voltage rating.
• Equipment in variable‑voltage environments — Designed for systems exposed to voltage fluctuations where stable capacitance and endurance are required.

Unique Advantages

• High voltage capability: 450 V rating enables use in medium‑voltage DC bus and rectifier applications.
• Large capacitance in a screw‑terminal package: 2700 µF provides substantial energy storage while the screw terminals simplify high-current connections and mechanical mounting.
• Designed for dynamic loads: High ripple current ratings at both 120 Hz and 10 kHz support applications with fast switching and regenerative energy flow.
• Proven endurance: 5000 hours at 85 °C under rated stress and validated charge–discharge cycling capability improve predictability in long‑life systems.
• Low leakage behavior: Specified leakage current limits after initial application of rated voltage aid in predictable bias performance.
• RoHS compliance: Meets directive requirements for restricted substances, simplifying regulatory considerations for equipment builders.
