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.
