Since it seems that inductors for high frequency circuits uses dielectric ceramics as the their material, I am concerned about magnetic flux leaking out.
  • Inductors (Coils)

A. Leakage of magnetic flux from an inductor may impact adjacent parts or peripheral circuits.
For this reason, please check the level of impact through experimental evaluation, etc.
In order to reduce the impact of magnetic flux leakage, countermeasures such as widening the distance between products or mounting them can be taken.
TDK's multilayer inductors for high frequency circuits (excluding the MLK series [Gigaspira structure]) have direction identification markings, which enable identification of the direction of magnetic flux.
