1 Scope

This part of GB/T 36103 specifies the standards and series of standards for ferrite core dimensions.

This section covers ferrite cores that are widely used and shaped in the industry. These ferrite cores are either included in national standards, or

Has a wide range of industrial applications. Where applicable, the current industry name in each standard will appear in the corresponding series of standards

section.

This section does not include a dedicated ferrite core for limited use, nor does it include a dedicated core that deviates from the standard core.

Example.

E24/25 (US) and E24.5 (Metric) are two similar cores, but they are included in this series of standards, respectively, because they meet national standards and are widely

application.

E-187 (US) and FEE19A (Japan) are two similar cores, but they are included in this series of standards, respectively, because they meet national standards and are widely

application.

EP5 has smaller size differences between different manufacturers, but only EP5 is given in this series because they are only small for a single basic product.

Variety.

Only one or two manufacturers produce ferrite cores that are generally considered a specialty product and are not suitable for use in this series.

Standard core. Ferrite cores produced by three or more competitors are generally included as candidates in this series of standards.

The IEC has issued an electrical standard for a series of ferrite cores, as well as a series of ferrite cores. a series of standards for ferrite

The modification of the body core will also be reflected in other series of ferrite core standards.

3 Conversion of current standards and systems and revision projects

The standards contained in the GB/T 36103 (IEC 62317) standard include current standards, standards being developed, and future

standard.

The new standards for logging in to the IEC website are as follows.

a) Project being revised. The number of the new project should be posted on the IEC website when the new working draft is published, and

Mark on the surface;

b) current standards. the version number should be updated at the time of the publication of each new revision of these standards; and in the foreword of subsequent editions

Description

c) Future new projects. The number of new projects should be selected in accordance with the standard of GB/T 36103 (IEC 62317).
