): The point where the core material can no longer support additional magnetic flux, causing a sharp drop in inductance.

Higher DCR leads to more heat loss and decreased efficiency. Smaller physical inductors often have higher DCR because they use thinner wire. Core Material: buy inductor

Best for very high-frequency RF applications because they have no core losses. Physical and Application Factors
