Additional Details

The 'R47M' in the part number indicates an inductance value of 0.47 μH with a tolerance of ±20%. The saturation current (Isat) and rated current (Irms) are important parameters for determining the inductor's ability to handle high currents without significant performance degradation or overheating. The T04 indicates a specific taping specification. Consult the official TDK datasheet for detailed electrical characteristics, temperature derating curves, and soldering recommendations. Proper PCB layout is essential to minimize parasitic inductance and capacitance, which can affect the inductor's performance and stability. Also, the SRF (Self Resonant Frequency) should be higher than the operating frequency for optimal performance.
