This standard specifies the basic dimensions of PQ cores made of magnetic oxides that are important in terms of mechanical interchangeability and the effective parameter values of the cores. This standard applies to PQ cores made of magnetic oxides. These cores are usually used under high magnetic flux density and can be used to make high-frequency switching power supply transformers and chokes.
