Additional Details

The 817CE-101M=P3 has a specific inductance value, typically measured in microhenries (µH). The '101M' designation in the part number indicates the inductance value and tolerance, with '101' representing 100 µH and 'M' indicating a ±20% tolerance. The saturation current specifies the maximum current the inductor can handle before its inductance value significantly decreases. The DC resistance (DCR) is an important parameter that determines the power loss due to resistive heating. The inductor is constructed using a ferrite core and a copper winding, and it is shielded to minimize electromagnetic radiation. It is also designed to withstand high temperatures during soldering processes.
