IEC 62024-2:20 20作为IEC 62024-2:20 20 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 62024-2:20 20规定了小型电感器额定直流电限的测量方法。用于确定额定值的标准化测量方法使用户能够准确地比较各种制造商数据手册中给出的当前额定值。本文件适用于尺寸符合IEC 62025-1且通常额定电流小于22A的引线和表面贴装电感器，但也可使用额定电流大于22A的电感器，这些电感器在本文件的尺寸限制范围内（大约不大于12mm x 12mm的占地面积）。这些电感器通常用于构建在PCB上的DC-DC转换器、用于电气和电信设备以及小型开关电源单元。测量方法由仅由直流电引起的饱和和温升限制来定义。与上一版相比，此版本包括以下重大技术变更:-增加表2和图2b)。

IEC 62024-2:2020 is available as IEC 62024-2:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62024-2:2020 specifies the measuring methods of the rated direct current limits for small inductors. Standardized measuring methods for the determination of ratings enable users to accurately compare the current ratings given in various manufacturers’ data books. This document is applicable to leaded and surface mount inductors with dimensions according to IEC 62025-1 and generally with rated current less than 22 A, although inductors with rated current greater than 22 A are available that fall within the dimension restrictions of this document (no larger than a 12 mm x 12 mm footprint approximately). These inductors are typically used in DC-to-DC converters built on PCBs, for electric and telecommunication equipment, and small size switching power supply units. The measuring methods are defined by the saturation and temperature rise limitations induced solely by direct current. This edition includes the following significant technical changes with respect to the previous edition:
- addition of Table 2 and Figure 2 b).
