LQR2W222MSEGBN

The LQR2W222MSEGBN is an aluminum electrolytic capacitor in a screw-terminal, radial can package from Nichicon's LQR series. It provides 2.2 mF (2200 µF) capacitance at a 450 V rated voltage and is designed for high‑speed charge–discharge performance in demanding power electronics environments.

Typical use cases include high-frequency regenerative voltage handling for AC servomotors and general inverters, applications exposed to voltage fluctuations, and rectifier circuits such as voltage doublers. Key value comes from its high voltage rating, robust ripple current capability, and endurance under elevated temperature and charge–discharge cycling.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) rated at 450 V for high-voltage energy storage in power conversion and regeneration circuits.
• High-speed charge–discharge design — Engineered for rapid charge and discharge behavior suitable for regenerative and inverter applications as specified by the LQR series.
• Ripple current capability — Specified ripple current: 8.6 A at 120 Hz and 12.04 A at 10 kHz, supporting both low- and high-frequency ripple environments.
• Robust endurance — Endurance: 5,000 hours at 85 °C under DC bias plus rated ripple current; charge–discharge endurance per series data covers 20 million cycles (ΔV = rated × 0.3, 3 Hz) at room temperature.
• Operating range & tolerance — Operating temperature range −25 °C to +85 °C with capacitance tolerance of −20% to +20% (±20% at 120 Hz, 20 °C).
• Mechanical & mounting — Screw terminal radial can package for secure, low‑impedance connections; size dimension L: 10 × D: 6.35 cm and polarized construction.
• Leakage current specification — After 5 minutes at rated voltage, leakage current ≤ 3√V (µA) or 5 mA, whichever is smaller (at 20 °C), per datasheet.
• RoHS compliant — Conforms to RoHS Directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• AC servomotor drives — Absorbs and returns high-frequency regenerative energy, supporting dynamic motor control and braking systems.
• General inverters — Provides bulk energy storage and ripple filtering in inverter DC-link circuits for industrial drives and power conversion.
• Voltage-doubler rectifiers — Suited for rectifier circuits where stable high-voltage storage and charge–discharge performance are required.
• Equipment in fluctuating-voltage environments — Helps stabilize DC rails and handle transient energy during supply variations.

Unique Advantages

• High-voltage energy storage: 450 V rating with 2200 µF capacitance enables significant stored energy for DC-link and regenerative functions.
• Designed for high-speed cycling: LQR series high-speed charge–discharge characteristics and documented 20 million cycle endurance support applications with frequent energy transfers.
• Strong ripple handling: Explicit ripple current ratings at both 120 Hz and 10 kHz allow designers to size the capacitor for low- and high-frequency ripple conditions.
• Durability at elevated temperature: Specified 5,000 hours at 85 °C under rated conditions gives predictable life performance in warm operating environments.
• Secure screw-terminal connection: Radial screw-terminals provide reliable, low-impedance electrical and mechanical attachment for heavy-current power systems.
• Compliance and quality traceability: RoHS compliance and detailed datasheet specifications support regulatory and engineering documentation needs.
