Additional Details:

The IHLP4040DEERR36M5D has an inductance value of 0.36µH. The saturation current is a critical parameter for inductors used in power applications. The specific saturation current and RMS current ratings should be verified on the Vishay datasheet for this part number. It utilizes a composite construction for efficient performance. The 4040 designates the dimensions of the inductor (4.0mm x 4.0mm). The inductor's construction and materials are selected to minimize core losses at high switching frequencies, common in modern power converters.
