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.
