744870100 – WURTH

Overview

The Würth Elektronik 744870100 is a shielded 2-coil inductor array designed for robust noise suppression and signal integrity applications. Its unique series/parallel configurable inductance values (20 µH series, 5 µH parallel) offer design flexibility, but engineers must carefully consider the trade-off between higher series inductance for improved filtering and the reduced current handling capacity (1.35A series vs. 2.7A parallel) which can limit its use in high-power switching circuits without careful thermal management.

Key Features

• Dual Inductance Configuration: 20 µH (Series), 5 µH (Parallel)
• High Current Handling: Up to 2.7 A (Parallel)
• Low DC Resistance: 44 mΩ Max (Parallel)
• Shielded Construction for EMI Reduction
• Surface Mount (SMD) Package
• Dimensions: 12.50mm x 12.50mm x 8.50mm

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

• Common-mode noise filtering in high-speed data lines (e.g., USB, Ethernet)
• Power supply decoupling and ripple reduction in sensitive analog circuits
• EMI suppression in automotive infotainment systems
• Signal line conditioning in industrial automation controllers
