PD IEC/TR 63090 is a document that discusses dimensional tolerances of ferrite cores, as a result of which manufacturers and suppliers can ensure their products are fit for purpose.
PD IEC/TR 63090 gives guidelines on the dimensional tolerances of ferrite cores that are generally used by ferrite core suppliers. As a reference, this is useful for ferrite core suppliers and users when they design ferrite cores and/or the components which use the ferrite cores.
PD IEC/TR 63090 is considered as general information useful in the dialogue between ferrite core suppliers and users.
PD IEC/TR 63090 on Ferrite cores is relevant to:
The shrinkage of ready-to-press powders, the density of mouldings, the deformation of ferrite cores, etc., are considered as causes of variations in dimension.
PD IEC/TR 63090 provides dimensional tolerances of E-cores, ring cores, ETD/EER-core, ER-core and planar ER cores. The dimensional tolerance is considered according to the processing conditions, and the core part is classified into the following three conditions:
If you are a manufacturer, compliance with the best industry requirements on dimensions provided by PD IEC/TR 63090 can ensure your products meet the performance requirements of the end-use application.
