标准范围

IEC 60063:2015为电阻器的电阻和电容器的电容提供了一系列优选值。如IEC 60062中所述，具有定义的数值分辨率的这种系列的定义是用其各自的电容或电阻值标记和编码电容器和电阻器的基本先决条件。与上一版相比，此版本包括以下重大技术变更:-修订关于E系列与相应部件的电阻或电容值的容差之间的关系的信息；-引入关于可能从部件标记中扣除相关E系列以及相关公差的建议；-完成编辑修订。

IEC 60063:2015 provides series of preferred values for the resistance of resistors and for the capacitance of capacitors. The definition of such series with a defined numeric resolution is a basic prerequisite for the marking and coding of capacitors and resistors with their respective capacitance or resistance values as described in IEC 60062. This edition includes the following significant technical changes with respect to the previous edition:
- revision of the information on a relationship between an E Series and the tolerance of a resistance or capacitance value of a respective component;
- introduction of advice on a possible deduction from the marking of a component to an associated E Series and also to an associated tolerance;
- complete editorial revision.
