标准范围

IEC 60384-2:20 21适用于电子设备中使用的带金属化电极和聚对苯二甲酸乙二醇酯电介质的直流固定电容器。根据使用条件，这些电容器可能具有“自愈特性”。它们主要用于交流分量相对于额定电压较小的应用。涵盖了电容器的两个性能等级:1级用于长寿命应用，2级用于一般应用。电磁干扰抑制电容器和表面贴装固定金属化聚对苯二甲酸乙二醇酯薄膜介质DC电容器不包括在内，但分别由IEC 60384-14和IEC 60384-19涵盖。本文件的目的是规定优选的额定值和特性，并从IEC 60384-1适当的质量评定程序、试验和测量方法，并给出该类电容器的一般性能要求。参考本部分规范的详细规范中规定的试验严重性和要求具有相同或更高的性能水平，因为不允许更低的性能水平。与上一版相比，此版本包括以下重大技术变更:a)根据ISO/IEC指令第2部分:2018修订文件的所有部分，并与其他类似类型的文件协调一致；b)文件结构的组织遵循TC 40决定的新的部分规范结构；c)修订表格和第5条，以防止重复和矛盾。

IEC 60384-2:2021 applies to fixed capacitors for direct current, with metallized electrodes and polyethylene-terephthalate dielectric for use in electronic equipment.
These capacitors have a possibility of "self-healing properties" depending on conditions of use. They are primarily intended for applications where the AC component is small with respect to the rated voltage. Two performance grades of capacitors are covered: grade 1 for long-life application and grade 2 for general application.
Capacitors for electromagnetic interference suppression and surface mount fixed metallized polyethylene-terephthalate film dielectric DC capacitors are not included, but are covered by IEC 60384-14 and IEC 60384-19, respectively.
The object of this document is to prescribe preferred ratings and characteristics and to select from IEC 60384-1 the appropriate quality assessment procedures, tests and measuring methods, and to give general performance requirements for this type of capacitor. Test severities and requirements prescribed in detail specifications referring to this sectional specification are of equal or higher performance level, because lower performance levels are not permitted.
This edition includes the following significant technical changes with respect to the previous edition:
a) revision of all parts of the document based on the ISO/IEC Directives, Part 2:2018 and harmonization with other similar kinds of documents;
b) the document structure has been organized to follow the new sectional specification structure decided by TC 40;
c) revision of tables and Clause 5 so as to prevent duplications and contradictions.
