Additional Details

The 2R2M designation indicates an inductance value of 2.2 μH. The saturation current and rated current are important parameters to consider when selecting this inductor for a specific application. The saturation current is the current at which the inductance value drops significantly, while the rated current is the maximum continuous current that the inductor can handle without exceeding its temperature rating. The TDK datasheet provides detailed specifications, including inductance tolerance, DC resistance, saturation current, rated current, and self-resonant frequency. Proper PCB layout is crucial for minimizing EMI and maximizing performance. Consult the manufacturer's datasheet for recommended layout guidelines and application notes.
