4 Band Graphical Resistor Calculator
This calculator is valid only for four band resistors. For 5 bands resistors calculator click here. For 6 band resistors calculator click here.
Simply click on resistor to select/change the values from the drop-down menus for each band.
Color-coding equivalents for the four, five and six bands resistors.
To distinguish left from right there is a gap between the third and the fourth bands.
(A Zero Ohm resistor is usually marked with a single black band)
- band A is the first significant figure of component value (left side)
- band B is the second significant figure (some precision resistors have a third significant figure, and thus five bands).
- band C is the decimal multiplier
- band D if present, indicates tolerance of value in percent (no band means 20%)
