LQR2W562MSEJBB

The LQR2W562MSEJBB is a screw‑terminal, large‑can aluminum electrolytic capacitor from Nichicon's LQR series designed for high‑speed charge–discharge and demanding power applications. It delivers 5.6 mF capacitance at a 450 V rating, with construction and features targeted at regenerative and fluctuating‑voltage environments.

Typical use cases include AC servomotor regenerative circuits, general inverters, and rectifier circuits such as voltage‑doubler topologies where high ripple handling, low ESR and robust endurance are required. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 5.6 mF (5,600 μF) nominal capacitance with a 450 V rated voltage and tolerance of −20% to +20%.
• Low Equivalent Series Resistance (ESR) — 1.105 mΩ specified at 120 Hz to minimize conduction losses during high current pulses.
• High ripple current capability — 19.1 A at 120 Hz and 26.74 A at 10 kHz for effective smoothing and energy handling across both low and high frequency components.
• Endurance at elevated temperature — Rated for 5,000 hours at 85 °C under DC bias plus rated ripple current, with capacitance, tan δ and leakage current meeting the endurance criteria after recovery to 20 °C.
• Operating temperature range — Specified for −25 °C to +85 °C for operation in variable ambient conditions.
• Mounting & package — Screw terminal radial can package for secure, serviceable connections and robust mechanical retention; physical size: L: 13 × D: 9 cm.
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• AC servo drives and motor control — Handles high‑frequency regenerative voltages encountered in servo inverter regenerative loops and drive power stages.
• Power inverters and industrial drives — Provides bulk energy storage and ripple smoothing for general inverter topologies operating under fluctuating voltages.
• Voltage doubler rectifier circuits — Suited for rectifier implementations where series/parallel capacitor arrangements and high DC voltages are present.
• Equipment in fluctuating‑voltage environments — Designed for systems exposed to voltage swings where robust charge–discharge endurance is required.

Unique Advantages

• High ripple handling capability: Specified ripple currents at both 120 Hz and 10 kHz enable effective suppression of AC components across a wide frequency range.
• Low ESR for reduced losses: 1.105 mΩ ESR at 120 Hz reduces internal heating and improves efficiency during high current charge/discharge cycles.
• Designed for fast charge–discharge: LQR series construction and 85 °C endurance specification support high‑speed regenerative and pulse applications.
• Long endurance at elevated temperature: 5,000 hours at 85 °C under rated conditions provides predictable lifetime performance for industrial applications.
• Secure screw‑terminal connections: Screw terminals simplify installation and maintenance in power assemblies requiring robust electrical and mechanical connection.
• RoHS compliant: Meets current RoHS requirements for environmentally conscious designs.
