1st digit: 0 (zero)
1st, 2nd and 3rd digits: the first three
significant figures of the resistance
value at 25°C.
2nd and 3rd digits: the first two
significant figures of the resistance
value at 25°C.
NR ..
4th digit:
– for values > 100 Ω:
the number of ZEROS to be
added to the resistance value
4th digit:
– for values ≥ 10 Ω:
the number of ZEROS to be
added to the resistance value
– for values > 10 Ω and < 100 Ω:
the numerical 9 signifying that the
resistance value is to be multiplied
by 0.01
– for values ≥ 1 Ω and ≤ 9.9 Ω:
the numerical 9 signifying that the
resistance value is to be multiplied
by 0.1
– for values > 1 Ω and < 10 Ω:
the numerical 8 signifying that the
capacitance value is to be multiplied
by 0.01
Examples : 196 Ω: 1960
47.2 Ω: 4729
