744042100 – WURTH

Overview

The Würth Elektronik 744042100 is a shielded, wirewound drum core inductor designed for robust energy storage and filtering in demanding electronic circuits. Its primary function is to impede AC signals while allowing DC current to pass, crucial for power supply regulation and noise suppression. A key design consideration for this 10 µH component is the trade-off between its relatively high DC resistance (150 mΩ max) and its ability to handle 1.3 A, which can impact power efficiency in high-current applications where minimizing thermal losses is paramount.
