21、defining the designation nomenclature for the major physical attributes of soft ferrite core shapes. The purpose of this standard is to facilitate uniform usage of dimensional characters by manufacturers, specifiers, and users when describing core dimensions on drawings, in tables, and on catalogue

Only one character per dimension per ferrite piece shall be used. Characters 2B and 2D shall be used for core sets such as EP, PQ, Pot and RM. 4 Dimension descriptions
24、 Table 1 and Table 2 describe the alphabetic character assignments for the major dimensions of ferrite shapes.
