Metal electrode leadless face. A further surface mount resistor code scheme or smd resistor coding scheme has started to be used and it is aimed at 1 tolerance smd resistors ie.

Smd resistor chart calculate find the value of smd resistor.

Surface mount resistor codes 01c. The following table lists all commonly used smd resistors marked with the eia 96 code from 1 ohm to 976 mohms. The standard 3 and 4 digit code does not give us a way to determine the smd resistors tolerance. Looking at the image you see 4.

They are used where very high reliability and performance are required. However the small size of smt resistors makes the figures difficult to read. Therefore new resistor smd codes were developed.

As higher tolerance resistors are used further figures are needed. These tiny chips are marked with three 3 or four 4 digit codes which is called smd resistor codes to indicate their resistance values. 3 digit smd resistor codes 4 digit eia 96 smd resistor codes smd resistor stands for surface mount device taken out from smt surface mount technology resistor.

Unlike through hole resisors which use colored bands to determine the value surface mount resistor have numbers and sometimes letters. The name comes from the words. The most commonly seen codes are the three and four digit system and an electronic industries alliance eia system called eia 96.

See also the smd resistor calculator and a short tutorial on how to read smd resistors. Eia marking code for surface mount smd resistors 01s 1r 02s 1r02 03s 1r05 04s 1r07 05s 1r1 06s 1r13 07s 1r15 08s 1r18 09s 1r21 10s 1r24. Because of the small size of smd resistors there is often not room for the traditional color band code to be printed on them.

Example of smd resistor codes. Smt resistor markings and codes. Reading surface mount resistor codes.

11 may 09 marking of melf resistor styles 0102 0204 0207 color code acc. Those using the eia96 or e 96 resistor series. I will teach you how to take those letters and digits and determine the value.

Another form of surface mount resistor that can be used for some applications is known as a melf resistor. In most cases however youll find that a surface mount resistor marked with the 3 digit code has a tolerance of 5 and a resistor marked with 4 digit code or the new eia 96 code has a tolerance of 1 or less.
