As we know, the inductance value will influence inductors application, today let’s talk about how to select an inductors based on inductance value.

During the inductance is almost not stable during the entire working period of the components,  understand the effective value scope is particularly important. Thus, you should know your power circuit's inductance scope clearly. For inductors in power switching applications, the allowable harmonic distortion current & transient response determine the inductance request. Generally, harmonic distortion current maintain at load output current's 30% or more. While the inductor is used in filtering application, its characteristics impedance should be high enough to attenuate the overall target noise frequency. Engineers find out the reasonable inductance value based on online design tools & formula calculations.
