14、ite cores. It is intended that this standard will include ferrite cores which are widely used and referenced in industry, either because they are included in national standards, or because they are seen to have broad-based use in industry. Where applicable, it is intended that the existing industria
15、l name for each standard part should appear with the part within this series. It is intended that this standard will exclude ferrite cores which are specialty cores with limited use. Also, special cores which are only marginal variations upon standard cores are excluded. Examples: E24/25 (USA) and E
16、24,5 (Metric) are two similar parts, yet they are included separately in this series because they are national standards, widely used. E-187 (USA) and FEE19A (Japan) are two similar parts, yet they are included separately in this series because they are national standards, widely used. EP5 has small
17、 dimensional differences when comparing different manufacturers, yet only one EP5 is shown in this series, because they are only minor variations on the single basic part. A ferrite core produced by only one or two suppliers may generally be considered a specialty part, and not suitable as a standar
18、d core within this series. A ferrite core produced by three or more competing manufacturers may generally be considered to be a candidate to be included in this series. IEC publishes electrical standards for families of ferrite cores, as well as this series of dimensional standards for families of f
19、errite cores. Modifications to the ferrite cores listed in one type of standard should be reflected in the other type. 2 Normative references The following referenced documents are indispensable for the application of this document.

The
24、new references should be recorded on the IEC web site as follows: a) for existing projects: the new project numbers should be recorded on the IEC web site at the time of circulation of next working drafts, with an explanatory note on the cover sheet; b) for existing publications: the publication num
25、bers should be updated at the time of each new revision of these standards. An explanatory note should be included in the foreword of future publications; c) for future new projects, the new project numbers should be selected to be consistent with the IEC 62317 series. A table showing existing proje
26、ct (or publication) references and the proposed new project (or publication) references is given in Table A.1. 4 Dimension descriptions Table 1 and Table 2 describe the alphabetic character assignments for the major dimensions of ferrite shapes. All other minor core dimension designations are left t
27、o the discretion of the specifier.

29、parallel width K Centre post offset dimension S Slot width in outside legs T Distance between slot depths in outside legs 5 Locations and functions of core parts and surfaces (see Figure 1) 5.1 Mating surfaces These surfaces are generally ground in order to reduce the residual air gap between the tw
30、o core halves. Consequently, irregularities on these surfaces shall be considered as major ones, and carefully evaluated with regard to their influence on the magnetic properties of the complete circuit. 5.2 Centre post This should be considered as the most important part of the core due to its func
31、tion of carrying the total flux generated by the winding. The centre post of ferrite cores is generally circular (with or without a hole) or rectangular. 5.3 Outer walls or legs The main function of the outer walls (e.g. pot-cores) or the outer legs (e.g. E-cores) is to guide the magnetic flux in a
32、closed magnetic circuit. 5.4 Back wall, bottom and back surfaces The back wall has the same magnetic function as the outer walls or legs; it may include wire-slots and wire-way areas (e.g. on RM-cores), the shapes and dimensions of which are dictated by the winding and isolation requirements. Beside
33、s accommodating the clamping, the back surface (ground or not) serves as a reference plane for grinding the mating surface in order to achieve the required parallelism and flatness. 5.5 Wire-slot area Lateral area of the outer walls, interfacing with the cut-out portion. 5.6 Wire-way area This is lo
34、cated on the bottom (inside) surface of the back wall, running radially from the centre post to the wire-slot, centred with respect to the wire-slot. EN 62317-1:2007 5 It takes out the leads of the wound coil from inside to outside for termination. 5.7 Clamping recess area Recess area on the back wa
35、ll is to accommodate clamping clips.
