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.
BS EN IEC 63093-9 on ferrite cores is relevant to:
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.
BS EN IEC 63093-9:2020 supersedes BS EN 62317‑9:2006 and BS EN 60424‑5:2009, which are withdrawn and include some technical changes:
