☑ Resistor Temperature Coefficient Color Code

Resistor color code calculator the calculator above will display the value the tolerance and performs a simple check to verify if the calculated resistance matches one of the eia standard values. In the case of a 3 or 4 band resistor the first two band indicate the significant digits and the third indicates the multiplier.

There is an additional color strip as temperature coefficient in 6 band resistor color code for high accuracy and precision.

Resistor temperature coefficient color code. Select the first 3 or 4 bands for 20 10 or 5 resistors and all 5 bands for precision 2 or less 5 band resistors. An electronic color code is used to indicate the values or ratings of electronic components usually for resistors but also for capacitors inductors diodes and others. A thermistor is a temperature sensitive resistor they are often used as a temperature sensor.

The number of colored bands can be from 3 to 6. The tcr is calculated as the average slope of the resistance value over this interval. Resistor color codes chart.

To use this tool simply click on a particular color and number and watch how the actual bands on the resistor illustration change. By using the color code chart one finds that green stands for 5 and blue for 6. The value is thus 56100 5600 w.

Color bands are used because they can be easily and cheaply printed on a small electronic component. This is accurate for linear relations since the tcr is constant at every temperature. In the example on the left these bands are green blue red and gold.

These resistors have two bands for the resistance value one multiplier and one tolerance band. To read the six strip colors codes on a resistor the first second and third strip color codes shows the first significant second significant and third significant figures respectively. In the case of 5 band and 6 band resistors the first three bands indicate the significant digits and the fourth band indicates the multiplier.

A separate code the 25 pair color code is used to identify wires in some telecommunications cables. Different codes are used for wire leads on devices such as transformers or in building wiring. All resistors have some dependency on temperature which is described by their temperature coefficient.

Resistor color coding color coding is a method used to indicate the resistive value tolerance and temperature coefficient of resistors with low wattage rating because of their small size. The four band color code is the most common variation. The temperature coefficient of resistance for a resistor is determined by measuring the resistances values over an appropriate temperature range.

This chart shows you how you can read the resistor color bands. The colored bands on the resistors denote the value of resistance in resistor tolerance and sometimes temperature coefficient. The fourth strip shows the multiplier.

The number of colored bands can be from 3 to 6. Our resistor color code calculator is a handy tool for reading carbon composition resistors whether its a 4 band 5 band or 6 band type. In most cases for fixed or variable resistors the temperature coefficient is minimized but in the case of thermistors a high coefficient is achieved.

The term thermistor is a contraction of the words thermal and resistor.
