Resistance Value:
• E-24 series:
1st digit is “0”
2nd & 3rd digits are the significant
figures of the resistance
4th indicate the number of zeros:
“J” ~ 0.1, “K” ~ 0.01
Ex. 4.7Ω ~ 47J, 4.7KΩ ~ 472
• E-96 series:
1st to 3rd digits are significant figures
of resistance
4th digit indicates the number of zeros
Ex. 1.33 KΩ = 1331
