APPENDIX B - Example of a standard for the main dimensions
of coil formers for square cores (RM-cores)
meeting the IEC primary standard
Specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of square cores (RM-cores) made of magnetic oxides, the dimensional limits for wound coil formers to be used with these cores and the locations of their terminal pins on a 2,54 mm printed wiring grid in relation to the base outlines of the cores.
