How to read the fuse ring

How to read the fuse ring

Answer:

but it is the first, second and third ring for the effective value, the fourth ring is a valid number after the number of "0", the fifth color ring number that error: 1% in brown, red for 2%, 0.5% green, 0.25% blue, 0.1% purple
so the resistance of the resistance: 220000Ω = 220 KΩ, the error is 5% 1.4.2 colored ring resistance: is a precision resistor, with five color ring to represent the resistance value, method and four-color ring resistance The same
four color ring followed by: red, red, yellow, gold. The first color ring red for 2, the second color ring red 2, are valid numbers, the third color ring yellow is 4, said the effective number after 4 "0", the fourth ring is golden, that the error is 5%
gold means 5%, silver means 10%. Note: colorless means 20%. Color and digital control brown red orange yellow green blue purple gray black gold and silver on behalf of the number 1 2 3 4 5 6 7 8 9 0 0.1 0.2 Nb represents the error% + 1-1 + 2-2 + 0.5-0.5 + 0.2-0.2 0.1 + 5-20 + 5-5 + 10-10 effective 0 number 1 2 3 4 5 6 7 8 9 0 -1 -2 cases have a resistance
The first and second ring color lines represent the two significant digits of the sequence, the third color ring represents the number of "0" (10 exponent) after the effective number, and the fourth color ring represents the number Error
