How to Read Resistor Color Code

This value is displayed in different ways and there are currently two standards for measuring how resistance appears with either color-coded markers or SMD codes. Try out our Resistor Color Code Calculator in our Tools section.

How To Read Resistor Color Codes Arrow Com Color Coding Coding Basic Electronic Circuits

Resistor Color Coding uses colored bands to quickly identify a resistors resistive value and its percentage of tolerance with the physical size of the resistor indicating its wattage rating.

. For very small electronic components a color code instead of printed text is used to indicate the value rating or and tolerance. A resistors number of bands might range from three to six. The capital letters represent the first letters of the colours and their positions the digit values.

Resistor color codes always have digits followed by a multiplier follower by a tolerance value. Brown Green Silver would be a 15 Giga Ohm resistor. The resistance value is indicated by the first two bands while the third band acts as a multiplier.

What are resistor color codes used for. 472 4710 2 4700 PF. How do You Measure a Resistor.

How To Read the 1K Resistor Color Code. That would be 950 Ohms. How to Use the Resistor Color Code Calculator.

But when the component is dirty it is difficult to read the position of a decimal point or comma so to overcome this misread British Standard BS 1852 Standard coding system is used. The last band gives the multiplier. Generally on larger power resistors the resistance value tolerance and even the power rating are written on the body of the resistor rather than color code.

To distinguish the reading direction the tolerance band width is sometimes printed with. 122 12kΩ 1. BB ROY of Great Britain had a Very Good Wife.

The bands are read from left to right. Lets look at how to read resistor colour codes look at an example and learn a mnemonic to remember the number sequence in this post. FSR with Arduino example code Analog voltage reading.

This tool is used to decode information for color banded axial lead resistors. Supports resistors with 3 4 5 and 6 bands. For example a resistor with brown green and green bands is rated at 15 mega-ohms 15000000 ohms.

Resistor Color Code Calculator. One common scheme is the RKM code following IEC 60062Rather than using a decimal separator this notation uses a letter loosely associated with SI prefixes corresponding with the parts resistance. If a capacitor has 682 code first check the last no here the last no is 2.

Resistors come in variations with 4 5 or more color bands where a 4-band color code is most common. The resistor color code was developed during the year 1920. This is the first digit of the resistance value.

To understand how to read the resistor color code for 3 456 band resistors you can use this color chart. It is assumed that you did not read the bands from outside to inside which means Silver Green Brown. Read the color bands from left to right.

Resistor Color Code Band 1 Band 2 Band 322 ohm R22 Red Red Silver27 ohm R27 Red Purple Silver33 ohm R33 Orange Orange Silver39 ohm R39 Orange White Silver47 ohm R47 Yellow Purple Silver Notation Tolerance56 ohm R56 Green Blue Silver68 ohm R68 Blue Gray Silver82 ohm R82 Gray Red Silver 10 ohm 1R0 Brown Black Gold 11 ohm 1R1 Brown Brown. For example 204 2010 4 200000 PF. See specific codes for 10K 220 Ohm and other popular resistor capacities.

EDGELEC 100pcs 330 ohm Resistor 14w 025 Watt 1 Tolerance Metal Film Fixed Resistor Multiple Values of Resistance Optional. The online resistor calculator is a tool by Utmel Electronic used to calculate resistor values for 4 band 5 band and 6 band resistors in the range of ohms Kilo Ohms and Mega Ohms typically. 330 3310 0 33 PF 10 0 1 Resistor color code calculator.

Standard Resistor Values and Color. And this resistance calculator is developed to calculate the color code using the resistor color codes on. Resistors with 6 bands are usually for high.

Resistor Color Code Table. Now that we have an idea to determine the resistance value of a given resistor. The United Kingdom adopted a color code scheme for such communication wherein red signified danger and white signified safety with other colors.

5 Band Resistor Color Code Calculator 6 Band Resistor Color Code Calculator. The Standard Resistor Color Code Chart. Please read the subsection Color Code Exceptions below for more information.

The reading direction is not always clear. When the value can be expressed without the need for a prefix that is multiplicator 1 an R is used instead of the. For example sometimes the extra band may indicate failure rate military specification or temperature coefficient older or specialized resistors.

Resistor Colour Code Mnemonic. Band One 1st Digit. Now the multiplier is 10 2.

The color bands are printed on the body of tiny resistor components. The colors on the first 2 or 3 bands correspond to numbers from 0 to 9 which represent the significant digits of the resistors ohmic value. Components and wires are coded with colors to identify their value and function.

The first band is brown which corresponds to the value 1. This resistor type is called not surprisingly the blower motor resistor. The Resistor Color Code Calculator identifies the value and tolerance of a color coded resistor given its bands colors.

Fillable and printable Ral Color Chart Template 2022. In that case the blower motor resistor will fail repeatedly. Worn blower motor causes repeat blower motor resistor failure.

A chip resistor marked with the standard 3 digit code and a short bar below the marking denotes a precision 1 or less resistor with a value taken from the E24 series these values are usually reserved for 5 resistors. Learn how to read the 4 or 5-band resistor color codes that show Ohm value. Now that you have wired up the sensor you can upload the following example code using the Arduino IDE.

However other factors can cause the blower motor resistor to fail prematurely. The value that you will see time and time again is resistance R. 50 out of 5 stars 220 ohm resistor.

502 5010 2 5000 PF. Position the resistor with this band on the right side and again read your resistor from left to right. The notation to state a resistors value in a circuit diagram varies.

For a four band resistor each band has a specific role. Specification for this product family. Select the number of bands then their colors to determine the value and tolerance of the resistors or.

You can remember the colour code values using the following mnemonic. UNITS 1000 nanofaradnF 1 microfaradµF 1 picofarad 10-12 farads. There are exceptions to this 5-band color system.

This sketch will read out the sensor data from the analog input of the Arduino and display the output in the serial monitor. With that knowledge realize that on a four-band resistor the third color will always be blue 106 or less and on a five-band resistor the fourth color will always be green 105 or. The earliest examples of color codes in use are for long-distance communication by use of flags as in semaphore communication.

An SMD resistor with a marking of 0 00 000 or 0000 is a jumper a zero-ohm link. - Basic resistor values range from 01 Ohm to 10 Megaohms. From the above chart each color band on the resistor represents a number.

A color code is a system for displaying information by using different colors. Also the tolerance is a - value which means the real value of the resistor is something between - 20 of the nominal value of 950 Ohms in this case. As a blower motor ages and wears it can draw more currentmore current than the blower motor resistor was designed to handle.
