Annotation of standard text IEC 63093-4-ed.1.0 :
IEC 63093-4:2019 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of RM-cores and low-profile RM-cores made of ferrite, and the locations of their terminal pins on a 2,54 mm printed wiring grid in relation to the base outlines of the cores. It also gives guidance on allowable limits of surface irregularities applicable to RM-cores in accordance with the relevant generic specification. The selection of core sizes for this document is based on the philosophy of including those sizes which are industrial standards, either by inclusion in a national standard, or by broad-based use in industry. This document is a specification useful in the negotiations between ferrite core manufacturers and customers about surface irregularities. This first edition cancels and replaces the first edition of IEC 62317-4 published in 2005 and the second edition of IEC 60424-2 published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 62317-4:2005 and IEC 60424-2:2015: a) IEC 63093-4 integrates the contents of IEC 62317-4:2005 and IEC 60424-2:2015; b) IEC 60424-2:2015, Table 2, has been included in Annex C as Table C.1. LIEC 63093-4:2019 specifie les dimensions qui jouent un role majeur dans linterchangeabilite mecanique dune gamme preferentielle de noyaux RM et de noyaux RM extra plats constitues de ferrite, et les emplacements de leurs broches de sortie sur une grille au pas de 2,54 mm dun circuit imprime par rapport aux encombrements de base des noyaux. Elle fournit egalement des recommandations sur les limites dirregularites de surface admissibles des noyaux RM, conformement a la specification generique applicable. Le choix de la taille des noyaux pour le present document est fonde sur la philosophie consistant a introduire des tailles qui correspondent a des normes industrielles, soit par une prise en compte dans une norme nationale, soit par le biais dune utilisation a grande echelle dans lindustrie. Le present document est une specification utile pour les negociations entre les fabricants de noyaux ferrites et les clients a propos des irregularites de surface. Cette premiere edition annule et remplace la premiere edition de lIEC 62317-4 parue en 2005 et la deuxieme edition de lIEC 60424-2 parue en 2015. Cette edition constitue une revision technique. La presente edition inclut les modifications techniques majeures suivantes par rapport a lIEC 623174:2005 et a lIEC 60424-2:2015: a) lIEC 63093-4 integre le contenu de lIEC 62317-4:2005 et de lIEC 60424-2:2015; b) le Tableau 2 de lIEC 60424-2:2015 a ete inclus dans lAnnexe C en tant que Tableau C.1.
