电子设备用固定电容器.第2部分:分规范.金属化聚乙烯对苯二甲酸酯膜介质直流固定电容器

[中文适用范围]： “IEC 60384 的这一部分适用于电子设备中使用的带有金属化电极和聚对苯二甲酸乙二醇酯电介质的直流固定电容器。根据使用条件，这些电容器可能具有“自愈特性”。它们主要用于适用于交流分量相对于额定电压较小的应用。涵盖两个性能等级的电容器@ 1 级用于长寿命应用，2 级用于一般应用。用于抑制电磁干扰和表面贴装固定金属化聚对苯二甲酸乙二醇酯的电容器薄膜介电直流电容器不包括在内，但分别由 IEC 60384-14 和 IEC 60384-19 涵盖。” [外文原描述]： IEC 60384-2:2011 applies to fixed capacitors for direct current, with metallized electrodes and polyethylene-terephthalate dielectric for use in electronic equipment. These capacitors may have "self-healing properties" depending on conditions of use. They are primarily intended for applications where the a.c. component is small with respect to the rated voltage. Two performance grades of capacitors are covered, Grade 1 for long-life application and Grade 2 for general application. Capacitors for electromagnetic interference suppression and surface mount fixed metallized polyethylene-terephthalate film dielectric d.c. capacitors are not included, but are covered by IEC 60384-14 and IEC 60384-19 respectively. This fourth edition cancels and replaces the third edition published in 2005 and contains the following significant technical changes with respect to the previous edition. - Table 1, Sampling plan together with numbers of permissible non-conformance for qualification approval test, has been adjusted. - Table 3, Lot-by-lot inspection, has been changed, highlighting assessment level EZ only. - Table 4, Periodic inspection, has been changed, highlighting assessment level EZ only. - The preferred values of rated voltages have been updated in conformance with the basic series of preferred values R5 and R10 given in ISO 3.
