Permeability inductance
WebFactors affecting the inductance of an inductor are illustrated in Figure: Where inductance is symbolized by L, measured in henries (H); area of the core is symbolized by A, measured in m²; permeability is symbolized by μ; the number of turns is symbolized by N. From the expression of the factor affecting inductance, we can see that either ... WebThe value of inductance or linking inductance does not follow a nice relationship so the parameters under which the circuit is designed may shift (if this saturation is unintentional). But some circuit designs rely on his effect to accomplish their roles. In some materials, the permeability drops a lot.

WebObviously, if permeability (µ) in the equation is unstable, then the inductance (L) will also be unstable to some degree as the current through the coil changes in magnitude. If the … WebThe primary factors for comparing power inductor performance are the 1) inductance value, 2) DC superposition characteristic, 3) temperature characteristic, 4) voltage endurance, and 5) leakage flux. Knowing these factors will enable you to select the power inductor structure which is suited to the required level of performance. 1) Inductance value
