Higher DCR leads to more heat loss and decreased efficiency. Smaller physical inductors often have higher DCR because they use thinner wire. Core Material:
Consider shielded inductors if your circuit is sensitive to electromagnetic interference (EMI) or if the inductor must sit near other high-frequency components. Where to Buy Inductor Market Size, Share, Trends & Growth Report, 2030
): The point where the core material can no longer support additional magnetic flux, causing a sharp drop in inductance.
The environment and board layout significantly influence which package you should buy:
