IEC 62317

IEC 62317 - a family of IEC standards defining mechanical dimensions of ferrite cores.

The standard is intended to include widely used ferrite core families. However, even if there are very similar sizes, e.g. E24/25 (USA) and E24,5 (metric), they are included separately due to their high popularity and definition in national standards.

On the other hand, a type of core produced by only one or two manufacturers would not be included.

Apart from the multi-part IEC 62317 standard itself there are other documents which are pertinent. These would be for instance:


 * IEC 62317-1 - general specification
 * IEC 62317-2 - pot cores
 * IEC 62317-3 - half pot cores
 * IEC 62317-4 - RM cores
 * IEC 62317-5 - EP cores
 * IEC 62317-6 - ETD cores
 * IEC 62317-7 - EER cores
 * IEC 62317-8 - E cores
 * IEC 62317-9 - Planar cores
 * IEC 62317-10 - PM cores
 * IEC 62317-11 - EC cores
 * IEC 62317-12 - uncoated rings
 * IEC 62317-13 - PQ cores
 * IEC 62317-14 - EFD cores

As of October 2013, some of these standards were not published yet, and other standards are applicable:


 * IEC 62323 - half pot cores
 * IEC/TR 61604 - uncoated rings
 * IEC 61247 - PM cores
 * IEC 61596 - EP cores
