IEC 63093-9:2020 specifies the shapes and dimensions of ferrite cores for inductive components (transformers and chokes), whose the coil is typically made of multi-layer boards (or the coil is part of the motherboard), and the effective parameter values used in calculations. This document gives guidelines on allowable limits of surface irregularities applicable to planar-cores as well. This document is considered as a sectional specification useful in the negotiation between ferrite core suppliers and users about surface irregularities. This first edition cancels and replaces the first edition of IEC 60424-5 published in 2009 and first edition of IEC 62317-9 published in 2006 and its Amendment 1:2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous editions of IEC 60424-5 and IEC 62317-9: a) IEC 63093-9 integrates IEC 60424-5 and IEC 62317-9; b) Table 1, Table 2 and Table 3 in IEC 60424-5:2009 have been moved to Annex B; c) some numbers are corrected in Table 4; d) Table 6 is amended following IEC 60205.
