The formula for breaking the code down is as follows.

How to calculate resistance value of smd resistor. Resistor color codes are used to indicate the value of resistance defined by radio manufacturer association in 1920 according to the international standards iec 60062. Ohms law use hindi. How to calculate the value of an smd resistor.

The third one letter is a multiplier in power of ten ie. The first two numbers will indicate the significant digits and the third will be the multiplier telling you the power of ten to which. 38c 24300 w 1.

Recently a new coding system the eia 96 has appeared on precision smds. If you are not able to find the exact value of resistor that you have calculated and then select the next coming value of resistor that you have calculated for example if the calculated value is 3135w you would use the closest standard value which is 330 w. Most chip resistors are marked with a 3 digit or 4 digit code the numerical equivalent of the familiar color code for through hole components.

The multiplying factor gives the final value of the resistor for example. Below are the rules to follow for reading the value of eia 96 smd resistors. Below are given calculators for different types of resistors such as 3 band 4 band 5 band and 6 band resistors.

92z 0887 w 1. 10 something and then must be multiply by the first two 2 significant digits. 01a 100 w 1.

The first two 2 digits or numbers will indicate the significant digits or numbers. 1st value 2nd value multiplier 3 9 1 390 ohm resistor 2 7 0 27 ohm resistor 2 3 3 23000 ohm or 23k ohm resistor there are some resistors which have 4 digits. Lesson 1 voltage current resistance engineering.

How to calculate the resistor value for parallel led. Namstey dosto aap sabhi ka fir se swagat hai aaj ki iss video me smd resistor code ko kaise calculate karegesmd resistor code value ko kaise nikale 3 digit 4 digit resistor code ke calculate. If the closest value is not close enough then you can make it by connecting resistors in series parallel configuration.
