Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 13: PQ-cores
This part of IEC 63093 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of PQ-cores and low-profile PQI-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 PQ-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. The general considerations that the design of this range of cores is based upon are given in Annex A.
Ferritkerne - Richtlinien zu Maßen und Grenzen von Oberflächenbeschädigungen - Teil 13: PQ-Kerne
Noyaux ferrites - Lignes directrices relatives aux dimensions et aux limites des irrégularités de surface - Partie 13: Noyaux PQ
La présente partie de l'IEC 63093 spécifie les dimensions qui jouent un rôle majeur dans l'interchangeabilité mécanique d'une gamme préférentielle de noyaux PQ et de noyaux PQI extra plats constitués de ferrite, et les emplacements de leurs broches de sortie sur une grille aux pas de 2,54 mm d'un circuit imprimé par rapport aux encombrements de base des noyaux. Elle fournit également des recommandations sur les limites des irrégularités de surface admissibles des noyaux PQ, conformément à la spécification générique applicable. Le choix de la taille des noyaux pour le présent document est fondé sur la philosophie consistant à introduire des tailles qui correspondent à des normes industrielles, soit par une prise en compte dans une norme nationale, soit par le biais d'une utilisation à grande échelle dans l'industrie. Le présent document est une spécification utile en cas de négociation entre les fabricants de noyaux ferrites et les clients à propos des irrégularités de surface. Les considérations générales sur lesquelles repose la conception de cette gamme de noyaux figurent dans l'Annexe A.
Feritna jedra - Smernice o merah in mejnih vrednostih površinskih nepravilnosti - 13. del: PQ-jedra
Ta del standarda IEC 63093 določa mere, ki so pomembne za mehansko medsebojno zamenljivost prednostnega razpona jeder PQ in razpona nizko profilnih feritnih jeder PQ, ter položaje njihovih priključkov na 2,54-mm mreži tiskanega vezja glede na osnovno sestavo jeder. Podaja tudi navodila glede omejitev površinskih nepravilnosti, ki veljajo za PQ-jedra v skladu z ustrezno splošno specifikacijo.
Izbira velikosti jeder za ta standard temelji na načelu vključevanja tistih velikosti, ki se na podlagi vključenosti v nacionalni standard ali vsesplošne uporabe v industriji smatrajo za industrijske velikosti.
Ta dokument je specifikacija, uporabna za sklepanje dogovorov o površinskih nepravilnostih med proizvajalci in uporabniki feritnih jeder.
Splošni premisleki, na podlagi katerih temelji zasnova tega razpona jeder, so podani v dodatku A.

FERRITE CORES – GUIDELINES ON DIMENSIONS

Part 13: PQ-cores
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,
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
