SMD Resistor Code Calculator SMD Resistor Code Calculator The surface mount resistor code calculator can be used to determine the resistance value of an SMD resistor using the markings found on the device. Choose the code format: three digit EIA, four digit EIA, or EIA-96. Then select the markings. Resistor Code Format Marking on the SMD resistor: Calculated resistance value: 1 kΩ This simple calculator will help you determine the value of any SMD resistor. To get started, input the 3 or 4 digit code and hit the "Calculate" button or Enter. Note: The program was tested rigorously, but it still may have a few bugs.

SMD Resistor Marking ⤄ Value Enter a resistor's value to get its marking or enter its marking to get a value. If over specified (both a value and marking are entered) the resistor's value is used to find its marking. This solver deals with the most common styles of marking (three or four numbers with optional 'R' and two number plus letter). Standard-tolerance SMD resistors are marked with a simple 3-digit code. The first two numbers will indicate the significant digits, and the third will be the multiplier, telling you the power of ten to which the two significant digits must be multiplied (or how many zeros to add). The size of SMD resistors is indicated by a numerical code, such as 0603. This code describes the length and width of the package. More information is available in the discussion of Resistor Sizes and Packages. Resistor SMD Code The following table lists all commonly used SMD resistors marked with the EIA-96 code from 1 ohm to 97.6 Mohms. See also the SMD resistor calculator and a short tutorial on how to read SMD resistors . More: 3-digit and 4-digit chip resistor examples. Through-hole color-coded resistor examples: E12 (10%), E24 (5%) and E48 (2%) .

The following tables list all commonly used four-digit SMD resistors from 0.1 ohm to 9.76 Mohms (E24 and E96 series). See also the SMD resistor calculator and a short tutorial on how to calculate the value of an SMD resistor . More chip resistor code examples: 3-digit and EIA-96 . Color-coded resistor examples: E12 (10%), E24 (5%) and E48 (2%) . Resistor Marking MARKING OF MELF-RESISTOR STYLES 0102, 0204, 0207 Color code acc. to IEC-publ. 62 Type: SMM0204 MS1 1st band (1st digit) 2nd band (2nd digit) 3rd band (multiplier) 4th band (tolerance) Type: SMM0102 SMM0204 MS1 PMM02041) 1st band (1st digit) 2nd band (2nd digit) 3rd band (3rd digit) 4th band (multiplier) 5th band (tolerance) Type: SMD Resistor Coding. SMD Resistors are usually coded with a numerical equivalent of the familiar three band colour code. In the same way as wire ended components, precision resistors (1% or better) may be marked with a four digit code. The first two (or 3) digits are the first two (or 3) digits of the resistance in ohms, and the third (or 4th. October 6, 2021 You've probably encountered this before — you have a circuit board that is poorly documented, and want to know the part number of a tiny SMD chip. Retro computer enthusiast.
SMD Resistor Coding Explained with Examples YouTube
For instance, a resistor marked as 4501 means '450' is the mantissa, and '1' is the power, resulting in 450 * 10 = 4.5 kΩ. Marking of 1% Tolerance SMD Resistors in 0603 Package. For 1% tolerance SMD resistors in the 0603 package, the marking is done using a combination of two digits and a letter, based on a specific table. EIA-96 system. Some resistors have a code consisting of two numbers and one letter at the end. the two numbers represent a number with three significant digits. The letter at the end represents a specific power of ten. You can find all these values in the table below. SMD resistors have a code consisting of three or four number or letters.
SMD Resistor stands for "Surface Mount device" (Taken out from SMT = Surface Mount Technology) Resistor. These tiny chips are marked with three (3) or four (4) digit codes which are called SMD Resistor codes to indicate their resistance values. The ultimate SMD marking codes database allows to quickly find the part number of a SMD component when you have only the marking code. See the database online at https://smd.yooneed.one/ Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world.

DECODING RESISTOR MARKINGS Though they may not display their value outright, most resistors are marked to show what their resistance is. PTH resistors use a color-coding system (which really adds some flair to circuits), and SMD resistors have their own value-marking system. Decoding the color bands Through-hole, axial resistors usually use the. The power rating of any resistor is very important, for surface mount resistors, the levels of power that can be dissipated are smaller than those of the normal types. The table below will serve as a guide for a typical power rating of some of the popular SMD resistor sizes. Note, this is just a guide, It may vary according to the manufacturer.
