A. There is the possibility of differences in the frequency characteristics of the impedance even if there are no changes in resistance values. Ferrites have a characteristic where μ changes when stress is applied. Therefore, when there is cracking in chip beads, the stress of the entirety changes and it causes changes in impedance.
