What is SRF (self-resonant frequency)?
  • Inductors (Coils)

A. An inductor has low distributed capacitance between terminal electrodes or the turns of a wire-wound conductor, and its inductance with such distributed capacitance resonates at a certain frequency. This frequency is called the self-resonant frequency, and the inductor does not function as an inductor beyond the self-resonant frequency.
When selecting an inductor for high frequency circuits and modules, it is not enough to simply consider the required inductance. You need to take into account that the self-resonant frequency must be sufficiently higher than the usage frequency.
