Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 11: EC-cores for use in power supply applications

IEC 63093-11:2018(E) specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of EC-cores made of ferrite and the essential dimensions of coil formers to be used with them, as well the effective parameter values to be used in calculations involving them. It also gives guidelines on allowable limits of surface irregularities applicable to EC-cores. The specifications contained in this document are useful in negotiations between ferrite core manufacturers and customers about surface irregularities. This first edition cancels and replaces the first edition of IEC 62317-11 published in 2015 and the second edition of IEC 60424-3 published in 2015. This edition constitutes a technical revision. This document includes the following significant technical changes with respect to IEC 62317­11:2015 and IEC 60424-3:2015:
This document integrates IEC 62317-11:2015 and IEC 60424­3:2015;
Table 3 – Allowable areas of chips for EC-cores, of IEC 60424-3:2015, has been moved to Annex B (informative) of this document.

Noyaux ferrites - Lignes directrices relatives aux dimensions et limites des irrégularités de surface - Partie 11 : Noyaux EC utilisés dans des applications d'alimentation électrique

L’IEC 63093-11:2018 spécifie les dimensions importantes pour l’interchangeabilité mécanique d’une plage préférentielle de noyaux EC en matériaux ferrites et les dimensions essentielles des supports de bobines à utiliser avec, ainsi que les valeurs des paramètres effectifs destinées aux calculs les impliquant. Elle donne également les lignes directrices relatives aux limites admissibles des irrégularités de surface applicables aux noyaux EC. Les spécifications du présent document sont utiles au dialogue entre les fabricants de noyaux en ferrite et leurs clients sur les irrégularités de surface.Cette première édition annule et remplace la première édition de l’IEC 62317-11 parue en 2015 et la deuxième édition de l’IEC 60424-3 parue en 2015. Cette édition constitue une révision technique. Ce document inclut les modifications techniques majeures suivantes par rapport à l'IEC 62317­11:2015 et à l’IEC 60424-3:2015:
ce document intègre l’IEC 62317-11:2015 et l’IEC 60424­3:2015;
le Tableau 3 – Surfaces admissibles des éclats pour les noyaux EC, de l’IEC 60424-3:2015, a été déplacé à l’Annexe B (informative) de ce document.

Feritna jedra - Smernice o merah in mejnih vrednostih površinskih nepravilnosti - 11. del: EC-jedra za uporabo v napajalnikih

Ta del standarda IEC 63093 določa mere, ki so pomembne za mehansko medsebojno zamenljivost prednostnega razpona feritnih EC-jeder, bistvene mere tuljave, ki se uporablja s temi jedri, in vrednosti efektivnih parametrov, ki se uporabljajo pri izračunih, povezanih z jedri. Podaja tudi smernice glede omejitev površinskih nepravilnosti, ki veljajo za EC-jedra.
Specifikacije v tem dokumentu so uporabne za sklepanje dogovorov o površinskih nepravilnostih med proizvajalci in uporabniki feritnih jeder.
