Additional Details:

The SCDS105R-4R7M-N has an inductance value of 4.7μH with a tolerance of ±20%. The high saturation current, typically around 6A, allows it to handle high current loads without significant inductance drop. The low DC resistance helps minimize power losses and improve the overall efficiency of the power supply. The shielded construction effectively reduces magnetic field leakage, minimizing EMI concerns.

The 'R' in the part number indicates that the product is RoHS compliant, and the 'N' signifies that it is suitable for lead-free soldering processes. The self-resonant frequency (SRF) is approximately 40 MHz. It is designed for surface mount assembly and is compatible with reflow soldering processes.
