Resistor Colour Code and Resistor Tolerances Explained

100 ohm 2w resistor color code

In the next tutorial about Resistors, we will look at connecting resistors together in a series chain and prove that the total resistance is the sum of all the resistors added together and that the current is common to a series circuit. Operating temperature range: Temperature Range: -55°C — +155°C, Max voltage: 350V. Mouser® and Mouser Electronics® are trademarks of Mouser Electronics, Inc. The E12 series comes in twelve resistance values per decade, A decade representing multiples of 10, i. The five and six band resistor colour code is more commonly associated with the high precision 1% and 2% film types while the common garden variety 5% and 10% general purpose types tend to use the four band resistor colour code.

These coloured painted bands produce a system of identification generally known as a Resistors Colour Code. The virtual Forum provides free access to more than 20 on-demand webinars which have been recorded at electronica. .

100 ohm 2w resistor color code

An international and universally accepted resistor colour code scheme was developed many years ago as a simple and quick way of identifying a resistors ohmic value no matter what its size or condition. It consists of a set of individual coloured rings or bands in spectral order representing each digit of the resistors value. This is the virtual version of the Power Electronics Forum at electronica with technical papers about innovative applications and technologies, trends and new product offerings covering the whole range of Power Electronics Components, Power Supplies and Batteries. However, the challenges are having improved measurement equipment available and to analyze the designs correctly. Obviously, it would be impractical to have available resistors of every possible value for example, 1Ω, 2Ω, 3Ω, 4Ω etc, because literally tens of hundreds of thousands, if not tens of millions of different resistors would need to exist to cover all the possible values. The overall benefit is reduced sizes for the total systems in all applications. The resistive value of the resistor is controlled by increasing the desired thickness, length or type of deposited film being used and highly accurate low tolerance resistors, down to 0.

Then the resistor colour code is read from left to right as illustrated below: The Standard Resistor Colour Code Chart The Resistor Colour Code Table Colour Digit Multiplier Tolerance Black 0 1 Brown 1 10 ± 1% Red 2 100 ± 2% Orange 3 1,000 Yellow 4 10,000 Green 5 100,000 ± 0. Resistors with tolerances lower than 2% are called precision resistors with the or lower tolerance resistors being more expensive. Metal films are precise and quiet, and work well in audio circuits, reducing noise and increasing circuit stability over a wide temperature range. Instead, resistors are manufactured in what are commonly known as Preferred values. Surface mount resistors generally have a ceramic substrate body onto which is deposited a thick layer of metal oxide resistance.

All other trademarks are the property of their respective owners. So to overcome this, small resistors use coloured painted bands to indicate both their resistive value and their tolerance with the physical size of the resistor indicating its wattage rating. Surface Mount Resistors are printed with either a 3 or 4-digit numerical code which is similar to that used on the more common axial type resistors to denote their resistive value. Other currency options may also be available - see Copyright ©2019 Mouser Electronics, Inc. Then we have seen that the resistor colour code system is used to identify the resistive value of a resistor.

Typical resistor tolerances for film resistors range from 1% to 10% while carbon resistors have tolerances up to 20%. The fourth and fifth bands are used to determine the percentage tolerance of the resistor. It is sometimes easier to remember the resistor colour code by using mnemonics or phrases that have a separate word in the phrase to represent each of the Ten + Two colours in the code. For example, take an E-12 series resistor, 10% tolerance with a preferred value of 3. Passive components from heat sinks, capacitors and coils get smaller. Again, by matching the colour of the second band with its associated number in the digit column of the colour chart we get the second digit of the resistance value and so on. Generally on larger power resistors, the resistor colour code systems is not required as the resistance value, tolerance, and even the power wattage rating are printed onto the actual body of the resistor instead of using the resistor colour code system.

Most five band resistors are precision resistors with tolerances of either 1% or 2% while most of the four band resistors have tolerances of 5%, 10% and 20%. A very high precision E192 series is now available with tolerances as low as ± 0. There are many different types of Resistor available which can be used in both electrical and electronic circuits to control the flow of current or to produce a voltage drop in many different ways. For example, for the E6 20% series there are six individual resistors or steps 1. The resistor colour code markings are always read one band at a time starting from the left to the right, with the larger width tolerance band oriented to the right side indicating its tolerance.

Resistors are available in a range of different resistance values from fractions of an Ohm Ω to millions of Ohms. All other trademarks are the property of their respective owners. For example, a 4,700Ω resistor is equivalent to a 4. Instead of sequential values of resistance from 1Ω and upwards, certain values of resistors exist within certain tolerance limits. These thick-lead versions of the resistors fit snugly into a breadboard with very little movement, so you should have few to no issues using them in your next project! Resistors come in a range of tolerances but the two most common are the E12 and the E24 series.
