74455022 – WURTH

The 74455022, manufactured by Wurth Elektronik, is a fixed-value surface mount inductor characterized by an inductance of 2.2 µH with a tolerance that is typically unspecified but implied to be within standard tolerances for this component class. It exhibits a saturation current rating of 2.4 A, indicating the DC current level at which the inductance value will typically drop by a defined percentage (often 10-30%). The component’s DC resistance (DCR) is 70 mΩ, a critical parameter affecting power dissipation and efficiency in circuit applications. This low DCR minimizes resistive losses when carrying the rated current. The 74455022 is designed for automated assembly using standard surface mount technology (SMT) reflow soldering processes. Its physical dimensions and footprint are crucial for PCB layout and thermal management considerations, necessitating reference to the manufacturer’s datasheet for detailed specifications.
