Overview
The Würth Elektronik 744878100 is a shielded, dual-coil inductor array designed for sophisticated signal integrity applications. Its primary function is to provide controlled impedance and EMI suppression, with a critical operational characteristic being the selectable series (20 µH) or parallel (5 µH) configurations. A key design consideration for engineers is managing the trade-off between inductance value and current handling capability; while the parallel configuration offers higher current capacity (1A), it sacrifices inductance density compared to the series mode (500mA). This component excels in environments demanding robust noise reduction.
Key Features
- Dual-coil, shielded construction
- Configurable inductance: 20 µH (Series) / 5 µH (Parallel)
- Current Rating: 1 A (Parallel) / 500 mA (Series)
- DC Resistance (DCR): 150 mΩ Max (Parallel)
- Operating Temperature Range: -40°C to 125°C
- Dimensions: 7.30mm x 7.30mm x 4.00mm (Surface Mount)
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.
- EMI filtering in high-speed data lines (e.g., USB, HDMI)
- Common-mode noise suppression in differential signaling
- Impedance matching in RF front-end circuitry
- Power supply decoupling for sensitive analog circuits
