电子设备用固定电容器 第9部分：分规范.2 类陶瓷介质固定电容器

[中文适用范围]： 本部分IEC 60384适用于具有定义温度系数（电介质2类）的固定陶瓷介质电容器，用于电子设备中，包括无引线电容器，但不包括固定表面安装多层陶瓷介质电容器，后者由IEC 60384-22（2类）涵盖。 电磁干扰抑制电容器不包括在内，但由IEC 60384-14涵盖。 本文件的目的是规定优选额定值和特性，并从IEC 60384-1:2021中选择适当的质量评估程序、测试和测量方法，并为这种类型的电容器提供一般性能要求。引用本文件的详细规范中规定的测试强度和需求提供了相同或更高性能级别的具体测试强度和需求。关于通用、分段和详细规范概念的进一步信息可在IEC 60384-1:2021的引言中找到。 [外文原描述]： IEC 60384-9:2024 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 60384-9:2024 is applicable to fixed capacitors of ceramic dielectric with a defined temperature coefficient (dielectric Class 2), intended for use in electronic equipment, including leadless capacitors but excluding fixed surface mount multilayer capacitors of ceramic dielectric, which are covered by IEC 60384-22 (Class 2). Capacitors for electromagnetic interference suppression are not included, but are covered by IEC 60384-14. The object of this document is to specify preferred ratings and characteristics and to select from IEC 60384-1:2021 the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of capacitor. Test severities and requirements specified in detail specifications referring to this document provide specific test severities and requirements of an equal or higher performance level. Further information on the conception of generic, sectional and detail specifications can be found in the Introduction of IEC 60384-1:2021. This edition includes the following significant technical changes with respect to the previous edition: a) The document has been completely restructured to comply with ISO/IEC Directives, Part 2 and to make it more useable; tables, figures and references have been revised accordingly. Annex X contains all cross-references of changes in clause/subclause numbers. b) The requirements of reference temperature 25 °C have been added in Table 7, Table 9, Table 11, Table 13 and Table 15. c) The table of temperature characteristics of capacitance for the reference temperature 25 °C have been added in Table B.1, Table B.2 and Table B.3. d) Annex B has been changed from informative to normative. e) Clause C.5 (Test schedule for quality conformance inspection) has been newly added to withdraw the blank detail specification: IEC 60384-9-1.
