BS EN IEC 63093-9:2020 pdf download.Ferrite cores一Guidelines on dimensions and the limits of surface irregularities
I Scope
IEC 63093 specifies the shapes and (transformers and chokes), whose the is part of the motherboard), and This document gives guidelines on
dimensions of ferrite cores for inductive coil is typically made of multi-layer boards the effective parameter values used in allowable limits of surface irregularities
This document is considered as a sectional specification useful in the negotiation between ferrite core suppliers and users about surface irregularities.
The general consideration upon which the design of this range of cores is based is given in Annex A.

4 Primary dimensions
4.1 Planar shapes and dimensions
The main shapes and dimensions shall be as given in the following figures and tables.
This part of components (or the coil calculations.applicable to planar-cores as well.
The main shapes, dimensions, and parameters for EL-cores are given in:
●Figure 1一Planar EL-core- and mating PLT-core;
●Table 1 - Dimensions of planar EL-core and mating PLT-core;
●Table 2一Effective parameter values and Amin values.
The main shape, dimensions, and parameters for low-profile E-cores are given in:
●Figure 2 - Low-profile E-core and mating PLT-core;
●Table 3 - Dimensions of low-profile E-core and mating PLT-core;
●Table 4 - Effective parameter values and Amin values.
The main shape, dimensions, and parameters for ER-cores are given in:
●Figure 3 - Low-profile ER-core and mating PLT-core;
●Table 5 - Dimensions of low-profile ER-core and mating PLT-core;
●Table 6 - Effective parameter values and Amin values.
A uniform dimensional nomenclature has been chosen in order to facilitate a comparison of major physical attributes among the different core shapes.
