Ceramic Resistor Markings

2 numbers to indicate the resistor value and 1 letter for the multiplier.

Ceramic resistor markings. Example of a wire wound resistor construction. The last band gives the multiplier. A wire wound resistor is a resistor where a wire with a high resistivity is wrapped around an insulating core to provide the resistance. I do not guarantee correctness of any information provided.

Basic resistor values range from 0 1 ohm to 10 megaohms. 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. This tool is for reference only. Position the resistor with this band on the right side and again read your resistor from left to right.

An smd resistor with a marking of 0 00 000 or 0000 is a jumper a zero ohm link. 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. Engineering toolbox resources tools and basic information for engineering and design of technical applications.

It is based on the e96 series thus aimed at resistors with 1 tolerance. Tolerance temperature package style and failure rate are integrated into some numbering schemes. Search is the most efficient way to navigate the engineering toolbox. Mil prf 55342 assigns part numbers using alpha numeric coding.

Resistors letters and digit codes. 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. 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. Three methods of resistor markings are predominant color coding numerical value coding and three digit symbol coding.

In this system the marking exists out of three digits. Wire wound resistor construction varies widely. For example a resistor with brown green and green bands is rated at 15 mega ohms 15 000 000 ohms.
