EN 62317-12:2016

Ferrite cores - Dimensions - Part 12: Ring cores

IEC 62317-12:2016(E) specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of ring-cores, also called toroid cores, and the effective parameter values to be used in calculations involving them. The selection of core sizes for this document is based on the philosophy of including those sizes which are industrial standards, meaning that they are in broad-based use within industry. See IEC 62317-1 for more detail concerning the philosophy of selecting core sizes to be included. This first edition cancels and replaces the first edition of IEC TR 61604 published in 1997. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC TR 61604: a) amendment of Clause 5 concerning the relationship between standard of European, Japanese and U.S.A. sizes; b) addition of Subclause 5.3 concerning coating.

Ferritkerne - Maße - Teil 12: Ringkerne

Noyaux de ferrite - Dimensions - Partie 12: Noyaux toriques

Feritna jedra - Mere - 12. del: Obročasta jedra

Ta del standarda IEC 62317 določa mere, ki so pomembne za mehansko medsebojno zamenljivost prednostnega razpona obročastih jeder, imenovanih tudi toroidna jedra, in dejanske vrednosti parametrov, ki se uporabljajo pri izračunih, povezanih s temi jedri.
Izbira velikosti jeder za ta dokument temelji na načelu vključevanja velikosti, ki predstavljajo industrijske standarde, kar pomeni, da so del vsesplošne uporabe v industriji. Za več podrobnosti glede načela izbiranja velikosti jeder, ki bodo vključena v standard, glej standard IEC 62317-1.
