The PCMB053T-4R7MS has an inductance value of 4.7μH (microhenries). The 'MS' likely refers to the tolerance of the inductance value. Key specifications include the saturation current (Isat), which is the DC current at which the inductance drops by a specified percentage (e.g., 10% or 20%), and the rated current. The datasheet will also provide information on the inductor's dimensions, operating temperature range, and other relevant parameters.
