Ceramic Resistor Markings

Therefore the eia 96 marking system has been created.

Ceramic resistor markings. Search is the most efficient way to navigate the engineering toolbox. The last band gives the multiplier. Letter and digit codes to indicating resistor values. 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.

Three methods of resistor markings are predominant color coding numerical value coding and three digit symbol coding. Example of a wire wound resistor construction. 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. 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.

A wire wound resistor is a resistor where a wire with a high resistivity is wrapped around an insulating core to provide the resistance. The manufacturing and choice of materials used is dependent on the way the resistor will be used in. 2 numbers to indicate the resistor value and 1 letter for the multiplier. Basic resistor values range from 0 1 ohm to 10 megaohms.

In this system the marking exists out of three digits. For example a resistor with brown green and green bands is rated at 15 mega ohms 15 000 000 ohms. Position the resistor with this band on the right side and again read your resistor from left to right. Resistors letters and digit codes.

Engineering toolbox resources tools and basic information for engineering and design of technical applications. 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. It is based on the e96 series thus aimed at resistors with 1 tolerance. Wire wound resistor construction varies widely.

I do not guarantee correctness of any information provided. Tolerance temperature package style and failure rate are integrated into some numbering schemes. Mil prf 55342 assigns part numbers using alpha numeric coding.
