	IEC E-24, E-96 Series Resistance Cross-Reference List
	E-24 Series (×10nΩ)	Unit: 1Ω,10Ω,100Ω,1KΩ,10KΩ,100KΩ,1MΩ
	Table 1
	E-96 Series (×10nΩ)	Unit: 1Ω,10Ω,100Ω,1KΩ,10KΩ,100KΩ,1M

	Resistance Value Marking
	E-24: using 3 digits. The first two digits are significant figures or resistance and the third onedenotes number of zeros. E-96: RC/RS05and RC/RS06 using four digits. The first three digits are significant figures of resistance and the fourth denotes number of zeros; RC/RS03 using the mixture of digit code andletter , The first two code are accordance with E-96 series resistance and the third is letter multiplied code (refer to the following tables). Decimal point is expressed by "R". Jumper by "000". 0402 no marking
