Additional Details:

The SWPA6020S4R7MT has an inductance of 4.7µH with a tolerance of ±20%. The saturation current (Isat) and rated current (Irms) are important characteristics to consider during the design process. These currents define the limit at which the inductance value will drop significantly or the inductor will overheat, respectively. The shielding construction uses a ferrite core to enclose the coil and minimize magnetic field leakage, contributing to low EMI. The part number denotes its physical dimensions and inductance value; 'S' means shielded, and 'MT' usually refers to tape and reel packaging for automated assembly. The low DCR minimizes power loss due to resistance in the coil, increasing overall efficiency.
