Additional Details:

The SWPA4012S2R2MT has an inductance value of 2.2µH with a tolerance of ±20%. It features a saturation current (Isat) of approximately 1.2A and a rated current (Irms) of around 1.1A. The low DC resistance (DCR) of this inductor contributes to its high efficiency. The shielding is achieved through a ferrite core construction, effectively containing the magnetic field and reducing radiated emissions. It is typically surface mountable. The part number reflects the physical dimensions and inductance value, with the 'S' indicating shielded construction and 'MT' often denoting tape and reel packaging for automated assembly.
