IEC 60063 Ed. 3.0 b:2015

Preferred number series for resistors and capacitors

IEC 60063 Ed. 3.0 b:2015

The preferred number series for resistors and capacitors are standardized sets of values used to ensure compatibility and coverage in electronic components.

The most commonly used preferred number series include:

  • E6 Series: Contains 6 values per decade, suitable for general applications.
  • E12 Series: Contains 12 values per decade, widely used for resistors and capacitors.
  • E24 Series: Contains 24 values per decade, offering finer granularity.
  • E48, E96, and E192 Series: Used for precision components with very fine value spacing.

These series are based on geometric progression and are recommended by international standards such as IEC and ANSI to ensure consistency and ease of selection in circuit design.

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.
