电子设备用固定电容器第22部分：分规范陶瓷介质固定表面安装多层电容器 2级

[中文适用范围]： IEC 60384-22:2019 RLV 包含官方 IEC 国际标准及其红线版本。 Redline 版本仅提供英文版本，为您提供了一种快速、简单的方法来比较官方 IEC 标准与其先前版本之间的所有更改。 IEC 60384-22:2019 适用于电子设备中使用的 2 类陶瓷电介质固定式非封装表面贴装多层电容器。这些电容器具有金属化连接垫或焊带，旨在安装在印刷板上，或直接安装在混合电路的基板上。用于抑制电磁干扰的电容器不包括在内，但属于 IEC 60384-14 的范围。本文件的目的是规定优选的额定值和特性，并从 IEC 60384-1 中选择适当的质量评估程序、测试和测量方法，并给出此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酷度和要求具有相同或更高的性能水平，不允许更低的性能水平。相对于前一版本，该版本包括以下重大技术变更： - 在可行的范围内根据 ISO/IEC 指令第 2 部分：2016（第七版）对结构进行了修订，并与 IEC 60384-21 保持一致； ——删除了6.2.2中关于允许无功功率的描述，因为它不适合本文件的目的； - 增加了附件A中0201M的尺寸。 [外文原描述]： IEC 60384-22:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60384-22:2019 is applicable to fixed unencapsulated surface mount multilayer capacitors of ceramic dielectric, Class 2, for use in electronic equipment. These capacitors have metallized connecting pads or soldering strips and are intended to be mounted on printed boards, or directly onto substrates for hybrid circuits. Capacitors for electromagnetic interference suppression are not included, but are covered by IEC 60384-14. 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 levels, lower performance levels are not permitted. This edition includes the following significant technical changes with respect to the previous edition: - revision of the structure in accordance with ISO/IEC Directives, Part 2:2016 (seventh edition) to the extent practicable, and for harmonizing with IEC 60384-21; - deletion of the description on the permissible reactive power in 6.2.2 because it is not appropriate for the purposes of this document; - the dimensions of 0201M in Annex A have been added.
