In other words, the resistor tolerance is the amount by which the resistance of a resistor may vary from its stated value. In three band resistor color codes, there is no tolerance band, so generally, 20% are assumed. G = +- 2%. It is based on the E96-series, thus aimed at resistors with 1% tolerance. Resistor Colour Code Calculator. You may click on any of the drop down box values and the color band display will change to the appropriate bands. The resistance value, tolerance, and wattage rating are generally printed onto the body of the resistor as color bands. Calculate. If you have a resistor with a gold or silver band on one end, you have a 5% or 10% tolerance resistor. This resistor color code calculator will help you determine the value of axial resistors marked with color bands. The color code for tolerance is as follows: brown - 1% . Farnell's resistor colour chart gives you band colours, resistance, and tolerance for various types of resistors to help you identify components in your electronics projects. 2.

This tool is used to calculate power, current, voltage or resistance. How to calculate the three band resistor color code. In this system, the marking exists out of three digits: 2 numbers to indicate the resistor value and 1 letter for the multiplier. The task is to find the resistance of 4-band resistor and 5-band resistor. You may use one of the following SI prefix after a value: p=pico, n=nano, u=micro, m=milli, k=kilo, M=mega, G=giga 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). Multiply the 2nd digit x. For example some low-value 1% resistors are available in E12 only. Different codes are used for wire leads on devices such as transformers or in building wiring. SMD resistor calculator. The site will find the best pair of standard-value resistors from the tolerance class that you selected. Resistor Color Code Calculator. The fourth band is the tolerance and represents the worst case variation one might expect from the nominal value. Quickly calculate the resistance, inductance or capacitance of electronic components. Resistor having only single black band is called as zero-ohm resistor. The schematic representation of the fit is also drawn. Fits and tolerance calculator for shaft and hole according to ISO 286-1 and ANSI B4.2 metric standards . Always read resistors from left to right. Resistor Colour Code Solver is a featured resistor value calculator which offers both color code to value and value to color code conversions. J = +- 5%. Hover above the tolerance for min. In case of 5 band and 6 band resistors, the 5 th band code is used for tolerance. There are four more or less commonly used resistor series, with 12, 24, 48, and 96 values per decade, respectively.
