What is BS EN IEC 63093-9 about?

BS EN IEC 63093-9 is the ninth part of a multi-series European standard that specifies the shapes and dimensions of ferrite cores for inductive components, whose coil is typically made of multi-layer boards and the effective parameter values used in calculations.

BS EN IEC 63093-9 gives guidelines on allowable limits of surface irregularities applicable to planar cores as well.

BS EN IEC 63093-9 is considered as a sectional specification useful in the negotiation between ferrite core suppliers and users about surface irregularities.

Who is BS EN IEC 63093-9 for?

BS EN IEC 63093-9 on ferrite cores is relevant to:

Ferrite core manufacturers and suppliers
Transformer manufacturers
Telecommunication industries
Electronics industry

Why should you use BS EN IEC 63093-9?

Planar cores are construction methods of inductive components with windings made of printed circuit tracks or copper stampings separated by insulating sheets or constructed with multi-layer circuit boards.

BS EN IEC 63093-9 specifies the optimum shapes and dimensions of cores for surface mounted devices (SMDs) and of cores for which the windings are constructed in the motherboard.

BS EN IEC 63093-9 ensures a reduction in the maximum allowable area of pull-outs in the inner surfaces, as a result of which improved quality of inner surfaces of the planar cores has been taken into consideration.

As a manufacturer, compliance with BS EN IEC 63093-9 can assist with maintaining uniformity and consistency in quality and performance of ferrite cores irrespective of the application where used.

What’s changed since the last update?

BS EN IEC 63093-9:2020 supersedes BS EN 62317‑9:2006 and BS EN 60424‑5:2009, which are withdrawn and include some technical changes:

IEC 63093-9 integrates IEC 60424-5 and IEC 62317-9

Table 1, Table 2, and Table 3 in IEC 60424-5:2009 have been moved to Annex B
Some numbers are corrected in Table 4
Table 6 is amended following IEC 60205
