LQR2W562MSEG

The LQR2W562MSEG is a screw‑terminal aluminum electrolytic capacitor in Nichicon’s LQR series designed for high‑speed charge–discharge and industrial power applications. It provides 5.6 mF (5600 µF) capacitance at a 450 V rating with a −25 °C to 85 °C operating temperature range.

Intended for inverter and motor drive environments, this capacitor targets applications with regenerative or fluctuating voltages and rectifier/voltage‑doubler circuits, delivering energy buffering, ripple handling and long endurance under elevated temperature conditions.

Key Features

• Capacitance & Voltage: 5600 µF (5.6 mF) nominal capacitance with a 450 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Screw‑Terminal Package: Radial can with screw terminals for secure electrical and mechanical connection in power assemblies.
• High Ripple Capability: Rated ripple current of 19.4 A at 120 Hz and 27.16 A at 10 kHz to support high‑frequency and low‑frequency ripple in inverter/drive systems.
• Low ESR: Equivalent series resistance of 1.6 mΩ measured at 120 Hz, supporting efficient energy transfer and reduced heating in high‑current cycles.
• Endurance at Elevated Temperature: Designed for 5000 hours of life at 85 °C under specified DC bias and ripple conditions.
• Polarized Design: Polarized electrolytic construction suitable for DC energy storage and smoothing functions.
• RoHS Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC Servo Drives: Energy buffering and handling of regenerative voltage in servo motor regenerative circuits.
• Inverters and Motor Controllers: Bulk energy storage and ripple smoothing for general inverters used in industrial drives.
• Voltage‑Doubler Rectifiers: Suitable for rectifier circuits that use voltage‑doubling topologies where high DC bus capacitance is required.
• Power Equipment in Fluctuating Voltage Areas: Provides stable DC support and tolerance to voltage variation in environments with frequent supply fluctuations.

Unique Advantages

• High DC Voltage Handling: 450 V rating enables use on high‑voltage DC buses common in inverters and industrial power supplies.
• Robust Ripple Endurance: Specified ripple currents at both 120 Hz and 10 kHz allow designers to address both line‑frequency and switching‑frequency stress without guesswork.
• Low Internal Losses: 1.6 mΩ ESR at 120 Hz reduces power dissipation and thermal rise during high‑current operation.
• Designed for Extended Life at High Temperature: 5000 hours endurance at 85 °C supports long service intervals in industrial installations.
• Secure Mechanical Termination: Screw‑terminal mounting simplifies high‑current connections and mechanical retention in power racks and enclosures.
• Regulatory Compliance: RoHS compliance supports use in designs targeting restricted‑substance requirements.
