Resistance Value:
• E-24 series:
1st digit is “0”
2nd & 3rd digits are for the significant
figures of the resistance
4th digit indicates 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 one denotes number of zeros.
Ex. 1.33 KΩ = 1331
Additional Information:
P = Panasert type
1 = Avisert type 1
2 = Avisert type 2
3 = Avisert type 3
0 = PT-52 mm, NIL for PT-26
