LQR2W562MSEGBN

The LQR2W562MSEGBN from Nichicon is a screw‑terminal aluminum electrolytic capacitor rated 5600 µF at 450 V with a −25 °C to +85 °C operating range. It is engineered for high‑speed charge/discharge and high ripple environments, making it well suited for regenerative and inverter power systems.

This part is targeted at industrial power electronics where large energy storage, robust terminal connections and high ripple handling are required—examples include AC servomotor regenerative circuits, general inverters, voltage‑doubler rectifiers and equipment operating in areas with fluctuating supply voltage. The product is RoHS‑compliant.

Key Features

• High capacitance and voltage: 5600 µF at 450 V provides significant energy storage for power conversion and smoothing in high‑voltage systems.
• Screw‑terminal mounting: Radial can with screw terminals delivers secure, low‑impedance connections suitable for high ripple currents and direct bus installation.
• Ripple current capability: Rated ripple current of 19.4 A at 120 Hz and 27.16 A at 10 kHz to support both low‑ and high‑frequency regenerative loads.
• Temperature and endurance: Operational from −25 °C to +85 °C with an endurance rating of 5000 hours at 85 °C under rated conditions.
• Charge–discharge durability: Specified to withstand 20 million charge–discharge cycles (ΔV = 0.3 × rated voltage, 3 Hz) at room temperature while meeting capacitance, tan δ and leakage current criteria.
• Leakage current specification: After 5 minutes at rated voltage, leakage current is limited to 3√(V) µA or 5 mA, whichever is smaller (measured at 20 °C).
• Low‑temperature stability: Impedance ratio Z(−25 °C)/Z(+20 °C) specified as 8, ensuring usable performance in colder environments.
• Polarized, general‑purpose design: Polar capacitor suitable for standard power supply and inverter topologies; capacitance tolerance ±20% at 120 Hz, 20 °C.
• Form factor: Physical size L: 19 × D: 6.35 cm with a maximum seated height of 7.48 inches, compatible with bolt‑down mounting and heavy‑duty bus layouts.

Typical Applications

• AC servomotor regenerative systems: Energy capture and smoothing in regenerative loops where high ripple and fast charge/discharge are required.
• General inverters: Bulk DC link and smoothing in inverter power stages exposed to fluctuating line voltages.
• Voltage‑doubler rectifier circuits: DC storage and filtering in rectifier stages that use higher peak voltages.
• Equipment in fluctuating voltage environments: Robust storage to stabilize DC buses in installations subject to supply variability.
• General purpose power electronics: Large‑value polarized capacitor for industrial power supplies and converters.

Unique Advantages

• Large energy density at high voltage: 5600 µF at 450 V enables substantial DC bus energy without series stacking of multiple lower‑voltage units.
• Robust power handling: High ripple current ratings at both 120 Hz and 10 kHz support demanding regenerative and switching environments.
• Secure mechanical and electrical connection: Screw terminals simplify heavy current wiring and reduce contact resistance compared with leaded terminals.
• Validated endurance and cycle life: 5000 hours at 85 °C and validated 20 million charge–discharge cycles provide long operational life in high‑stress applications.
• Measured low‑temperature performance: Specified impedance behavior at −25 °C helps maintain functionality in colder operating conditions.
• RoHS compliance: Meets applicable RoHS directives for use in regulated markets.
