BS EN IEC 63093-2:2020 pdf free.Ferrite cores—Guidelines on dimensions and the limits of surface irregularities.Pot-cores for use in telecommunications,
power supply, and filter applications.
BS EN IEC 63093-2 This part of IEC 63093 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.The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.IEC 60205, Calculation of the effective parameters of magnetic piece parts IEC 60401-1, Terms and nomenclature for cores made of magnetically soft ferrites – Part 1: Terms used for physical irregularities
IEC 60424-1，Ferrite cores 一Guidelines on the limits of surface irregularities – Part 1: General specification.The principal dimensions of pot-cores shall be as given in Table 1, Figure 1 and Figure 2. The dimensions of the cores may be checked by means of gauges. By way of example, a possible standard for these gauges is given in Annex B. In order to facilitate production it can be necessary to use gauges having dimensions differing from those given in Annex B, although 10 relaxation of the requirements for the dimensions of the cores given in Table 1 and in Table 2 is permitted.BS EN IEC 63093-2 pdf downlaod.
