- Scope
- This standard specifies the geometric dimensions and magnetic circuit dimensions of E-shaped cores made of magnetic oxides suitable for high magnetic flux density. The cores of this series are specifically intended for use in power transformers, for example as cores for switching power supplies with a switching frequency of 25kHz. This standard lists the preferred dimensions and tolerances of these cores that are important for mechanical and electrical interchangeability.
