The value of the resistor will be displayed below it. What is the 4th band on a resistor? Resistor Color Code Calculator. The site will find the best pair of standard-value resistors from the tolerance class that you selected. A separate code, the 25-pair color code, is used to identify wires in some telecommunications cables. The fourth band is the tolerance and represents the worst case variation one might expect from the nominal value. Resistor values are usually shown using coloured bands, each colour represents a number as shown in the table. Different codes are used for wire leads on devices such as transformers or in building wiring. Always read resistors from left to right. It is based on the E96-series, thus aimed at resistors with 1% tolerance. Calculator decodes parameters of the resistor (resistance value, tolerance, temperature coefficient) painted as colored bands on the resistor and vice versa. Resistor Calculator. Introduction. Details of the colour code system can be found here in the technical data section. It is used as a wire ( act as a jumper) to connect traces on a printed circuit board (PCB). The fourth and fifth bands are used to determine the percentage tolerance of the resistor. The color code for tolerance is as follows: brown - 1% . Tolerance is indicated as. Calculate. Generally, 5% tolerance resistors are available in E24 and 1% resistors in E96, but this is not a hard and fast rule. In other words, the resistor tolerance is the amount by which the resistance of a resistor may vary from its stated value. Resistor having only single black band is called as zero-ohm resistor. The resistance value, tolerance, and wattage rating are generally printed onto the body of the resistor as color bands. - Resistors never start with a metallic band on the left. ; The fourth band shows the tolerance (precision) of the resistor but this may be ignored for almost all circuits.
