Ceramic Resistor Markings

For example a resistor with brown green and green bands is rated at 15 mega ohms 15 000 000 ohms.

Ceramic resistor markings.

Position the resistor with this band on the right side and again read your resistor from left to right. Three methods of resistor markings are predominant color coding numerical value coding and three digit symbol coding. Tolerance temperature package style and failure rate are integrated into some numbering schemes. It is based on the e96 series thus aimed at resistors with 1 tolerance.

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. Wire wound resistor construction varies widely. In the resistor shown in the preceding figure the two digit number is 47 and the multiplier is 10 so the nominal value is an easy way to multiply a whole number by a power of 10 that is 10 0 10 1 10 2 10 3 and so on is to just append meaning tack on to the end the whole number with zeros and use the exponent which is the small. I do not guarantee correctness of any information provided.

2 numbers to indicate the resistor value and 1 letter for the multiplier. Example of a wire wound resistor construction. Search is the most efficient way to navigate the engineering toolbox. Basic resistor values range from 0 1 ohm to 10 megaohms.

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. In this system the marking exists out of three digits. Resistors letters and digit codes. The colors on the first 2 or 3 bands correspond to numbers from 0 to 9 which represent the significant digits of the resistor s ohmic value.

Engineering toolbox resources tools and basic information for engineering and design of technical applications. The manufacturing and choice of materials used is dependent on the way the resistor will be used in. This is a simple online calculator for color band resistor marking inductor color band marking ceramic or tantalum capacitor 3 digit marking and smd resistor 3 digit 4 digit 10 5 2 and eia 96 e96 1 tolerance code marking. The last band gives the multiplier.

Letter and digit codes to indicating resistor values. This tool is for reference only. An smd resistor with a marking of 0 00 000 or 0000 is a jumper a zero ohm link.
