Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 9: Planar cores

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.

Ferritkerne – Richtlinien zu Maßen und Grenzen von Oberflächenbeschädigungen - Teil 9: Planarkerne

Noyaux ferrites - Lignes directrices relatives aux dimensions et aux limites des irrégularités de surface - Partie 9: Noyaux planaires

L’IEC 63093-9:2020 spécifie les formes et dimensions des noyaux ferrites pour les composants inductifs (transformateurs et inductances) dont la bobine est généralement composée de la carte multicouche (ou la bobine fait partie de la carte mère) et des valeurs de paramètres effectifs utilisés dans les calculs. Le présent document donne des lignes directrices relatives aux limites admissibles des irrégularités de surface applicables également aux noyaux planaires. Le présent document est considéré comme une spécification intermédiaire utile dans les négociations entre les fournisseurs de noyaux ferrites et leurs utilisateurs portant sur les irrégularités de surface. Cette première édition annule et remplace la première édition de l’IEC 60424-5 parue en 2009 et la première édition de l’IEC 62317-9 parue en 2006 et son Amendement 1:2007. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport aux éditions précédentes de l’IEC 60424-5 et l’IEC 62317-9: a) l’IEC 63093-9 réunit l’IEC 60424-5 et l’IEC 62317-9; b) le Tableau 1, le Tableau 2 et le Tableau 3 contenus dans l’IEC 60424-5:2009 ont été déplacés vers l’Annexe B; c) certains chiffres du Tableau 4 sont corrigés; d) le Tableau 6 est modifié sur la base de l’IEC 60205.
