The CLF7045NIT-221M-CA inductor has specific electrical characteristics, including the inductance value (220 µH in this case, indicated by "221M"), the saturation current, and the DC resistance. The saturation current is the current at which the inductance starts to decrease significantly. The shielded construction minimizes EMI by containing the magnetic field within the inductor. Refer to the TDK Corporation datasheet for detailed specifications, including the operating temperature range, storage temperature range, and soldering conditions. The “CLF7045” portion of the part number indicates the physical dimensions of the inductor (7.0mm x 7.0mm x 4.5mm). The “NIT” likely indicates a specific core material. The “CA” suffix may specify a particular packaging option or termination finish.
