This International Standard specifies designation and marking codes for capacitors and resistors. It provides coding methods for the resistance or capacitance value and its tolerance, including colour coding for resistors. It provides coding for parameters specific either to capacitors, like e. g. the dielectric material, or to resistors, like e. g. the temperature coefficient of resistance (TCR). It also provides date code systems suitable for the marking of small components.
