Ferrite Stress Characteristics in Common-Mode Inductor Design

Ferrite materials are very sensitive to mechanical stress, either compressive or tensile.Under moderate stresses, the permeability of high-permeability materials is particularly affected by stress.Before using, the ferrite core must be inspected for cracks. There are two problems to pay attention to when using ferrite materials: (1) The encapsulant will causes stress. (2) Arranging the windings directly on the magnetic core will cause stress.
