適用范圍：This part of IEC 62317 specifies the standards and existing projects dealing with dimensionsof ferrite cores.It is intended that this standard will include ferrite cores which are widely used and referencedin industry, either because they are included in national standards, or because they are seento have broad-based use in industry. Where applicable, it is intended that the existingindustrial name for each standard part should appear with the part within this series.It is intended that this standard will exclude ferrite cores which are specialty cores with limiteduse. Also, special cores which are only marginal variations upon standard cores are excluded.Examples:E24/25 (USA) and E24,5 (Metric) are two similar parts, yet they are includedseparately in this series because they are national standards, widely used.E-187 (USA) and FEE19A (Japan) are two similar parts, yet they are includedseparately in this series because they are national standards, widely used.EP5 has small dimensional differences when comparing different manufacturers, yetonly one EP5 is shown in this series, because they are only minor variations on thesingle basic part.A ferrite core produced by only one or two suppliers may generally be considered aspecialty part, and not suitable as a standard core within this series. A ferrite coreproduced by three or more competing manufacturers may generally be considered tobe a candidate to be included in this series.IEC publishes electrical standards for families of ferrite cores, as well as this series ofdimensional standards for families of ferrite cores. Modifications to the ferrite cores listed inone type of standard should be reflected in the other type.
