IEC 60384-3:20 16适用于主要用于直流的固体（MnO2）电解质固定钽电解表面贴装电容器。在电子设备中的应用。考虑以下两种风格: -类型1-用外部材料保护的电容器； -类型2-不受外部材料保护的电容器。 与上一版相比，此版本包括以下重大技术变更: a)在可行范围内根据ISO/IEC指令第2部分:2011（第六版）修订结构，并协调其他类似类型的文件。 b)此外，还审查了第4条和所有表格，以防止重复和矛盾。

IEC 60384-3:2016 applies to fixed tantalum electrolytic surface mount capacitors with solid (MnO₂) electrolyte primarily intended for d.c. applications for use in electronic equipment. The following two styles are considered:
- Style 1 - Capacitors protected with external materials;
- Style 2 - Capacitors unprotected with external materials. 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.
