IEC 60384-18:20 16适用于主要用于直流的固体（MnO2）和非固体电解质的固定铝电解表面贴装电容器。在电子设备中的应用。它规定了首选的额定值和特性，并从IEC 60384-1:20 16中选择适当的质量评估程序、测试和测量方法，并给出了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重性和要求应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部分修订结构:2011年（第六版），以及其他类似文件之间的协调。 b)此外，还审查了第4条和所有表格，以防止重复和矛盾。

IEC 60384-18:2016 applies to fixed aluminium electrolytic surface mount capacitors with solid (MnO₂) and non-solid electrolyte primarily intended for d.c. applications for use in electronic equipment. It prescribes preferred ratings and characteristics and to select from IEC 60384-1:2016 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 should be 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 the structure in accordance with ISO/IEC Directives, Part 2:2011 (sixth edition) to the extent practicable, and harmonization between other similar kinds of documents.
b) In addition, Clause 4 and all the tables have been reviewed in order to prevent duplications and contradictions.
