标准摘要
[中文适用范围]: IEC 60384的本部分适用于电子设备中使用的陶瓷电介质@1级@的固定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,但包含在 IEC 60384-14 中。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测试严酷度和要求具有相同或更高的性能水平;不允许使用较低的性能水平。 [外文原描述]: IEC 60384-21:2019 is applicable to fixed unencapsulated surface mount multilayer capacitors of ceramic dielectric, Class 1, 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 to the extent practicable, and for harmonizing with IEC 60384-22; - 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.
