Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 2: Pot-cores for use in telecommunications, power supply, and filter applicationsPart

IEC 63093-2:2020 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of pot-cores made of ferrite, and the dimensional limits for coil formers to be used with them, as well as the effective parameter values to be used in calculations involving them. It also gives guidelines on the allowable limits of surface irregularities applicable to pot-cores in accordance with the relevant generic specification.
The selection of core sizes and shapes 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. See IEC 62317-1 for more detail concerning the philosophy of selecting core sizes to be included.
The general considerations upon which the design of this range of cores is based are given in Annex A.
This first edition cancels and replaces the first edition of IEC 62317-2 published in 2010. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition of IEC 62317-2:
a) addition of the limits of surface irregularities;
b) Table 4 and Table 5 are updated in accordance with IEC 60205:2016.

Noyaux ferrites - Dimensions - Partie 2: Circuits magnétiques en pots utilisés dans des applications de télécommunications, d'alimentation électrique et de filtre

L'IEC 63093-2:2020 spécifie les dimensions importantes pour l'interchangeabilité mécanique d'une gamme préférentielle de circuits magnétiques en pots en ferrite, les limites dimensionnelles des corps de bobines à utiliser avec ces pots et les valeurs de paramètres efficaces à utiliser dans les calculs les concernant. Elle donne également les lignes directrices relatives aux limites acceptables des irrégularités de surface applicables aux circuits magnétiques en pots conformément à la spécification générique correspondante. Le choix des tailles et formes de noyau pour le présent document repose sur la philosophie consistant à introduire les tailles qui correspondent à des normes industrielles, soit dans une norme nationale soit par une utilisation à grande échelle dans le secteur industriel. Voir l'IEC 62317-1 pour de plus amples informations relatives à ce principe de choix des tailles de noyau à inclure. Les considérations générales sur lesquelles s'appuie la conception de cette gamme de noyaux sont données à l'Annexe A. Cette première édition annule et remplace la première édition de l'IEC 62317-2 parue en 2010. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente de l'IEC 62317-2: a) ajout des limites des irrégularités de surface; b) le Tableau 4 et le Tableau 5 sont mis à jour conformément à l'IEC 60205:2016.

Part 2: Pot-cores for use in telecommunications,

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 63093-2 has been prepared by technical committee 51: Magnetic

components, ferrite and magnetic powder materials.

This first edition cancels and replaces the first edition of IEC 62317-2 published in 2010. This

edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition of IEC 62317-2:
a) addition of the limits of surface irregularities;
b) Table 4 and Table 5 are updated in accordance with IEC 60205:2016.
