Preferred number series for resistors and capacitors Ingestion-build-47786 Note: Coatings or protective layers1 Scope This International Standard 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. NOTE The number series defined in this standard are based on progressive ratios of 10r,
