Ceramic Resistor Markings

Therefore the eia 96 marking system has been created.

Ceramic resistor markings.

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

In this system the marking exists out of three digits. 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. The last band gives the multiplier. I do not guarantee correctness of any information provided.

Letter and digit codes to indicating resistor values. 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. Mil prf 55342 assigns part numbers using alpha numeric coding. It is based on the e96 series thus aimed at resistors with 1 tolerance.

Example of a wire wound resistor construction. An smd resistor with a marking of 0 00 000 or 0000 is a jumper a zero ohm link. Three methods of resistor markings are predominant color coding numerical value coding and three digit symbol coding. 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.

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 manufacturing and choice of materials used is dependent on the way the resistor will be used in. Tolerance temperature package style and failure rate are integrated into some numbering schemes. For example a resistor with brown green and green bands is rated at 15 mega ohms 15 000 000 ohms.

Engineering toolbox resources tools and basic information for engineering and design of technical applications. Position the resistor with this band on the right side and again read your resistor from left to right. 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.
