IEC 63093-9:2026 pdf download,Ferrite cores – Guidelines on dimensions and the limits of surface irregularities – Part 9: Planar cores.
IEC 63093-9:2026 outlines the shapes and dimensions of ferrite cores for inductive components such as transformers and chokes, specifically intended for use with coils constructed from multi-layer boards, integrated into motherboards, or consisting of flat conductor coils that are helically wound. This section also provides effective parameter values utilized in magnetic calculations for these planar cores. Moreover, it offers guidelines on permissible limits for surface irregularities relevant to planar cores. This document serves as a sectional specification that facilitates discussions between ferrite core suppliers and users regarding surface irregularities.
