Fast identification method for color ring resistance 4

For a 5-ring resistor, the 4th ring represents a number multiplied by a power of 10, and the numbers represented by the first 3 rings are multiplied by the nth power of 10 (where n is the number represented by the 4th ring).

4-color ring resistor:diode

The first color ring is a ten digit number, and the second color ring is a one digit number,

The third color ring is the multiplication factor, and the fourth color ring is the error rate

5-color ring resistor:diode

The first color ring is a hundred digit number, and the second color ring is a ten digit number,

The third color ring is a single digit number, and the fourth color ring is a multiplication factor,

The fifth ring represents the error rate.diode

For example, the color arrangement of a 5-color ring resistor is red, black, black, and brown,

The resistance value is 220 × 1=220 Ω, with an error of ± 1%

5-color ring resistors are usually metal film resistors with an error of ± 1%.diode
