How do I know what SMD resistor package I have?
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).
How do you read a SMD resistor?
For a three-digit SMD Resistor Code,
- the first two numbers indicates the significant digits for the resistance, e.g. “22” indicates 22 ohms.
- the third number will be a multiplier that must be multiplier by the first two numbers, or will indicate how many zeros should be added to the first two numbers.
How do I identify SMD components?
The Types of SMD Components Its first and second digits are significant digits, and the third digit indicates the multiple of 10, such as “103” indicates “10KΩ”, “472” is “4700Ω”. The letter “R” means a decimal point, for example, “R15” means “0.15Ω”.
How do I read a SMD code?
To identify a particular device, first identify the package style and note the ID code printed on the device. Next look up the code in the alphanumeric listing which forms the main part of the pdf book by looking for the first character in the left column.
How do I know how much my SMD components are worth?
Below are the rules to follow to know the value of EIA-96 SMD resistors.
- The first two (2) digits or numbers will indicate the significant digits or numbers.
- The third one “Letter” is a multiplier (in Power of Ten i.e. 10^ something) and then must be multiplied by the first Two (2) significant digits.
How can you tell the size of a SMD resistor?
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 availabe in the discussion of Resistor Sizes and Packages. Because of the small size of SMD resistors, there is often not room for the traditional color band code to be printed on them.
What is the JEDEC code for a SMD resistor?
Most manufacturers use the JEDEC standard. The size of the SMD resistor is represented by a digital code, such as 0603. This code contains the width and height of the package. Therefore, in the example of the 0603 Imperial code, this means that the length is 0.060 “and the width is 0.030”.
How big is a 1206 SMD resistor package?
For 1210 package style, the sizes are 3.20 x 2.60 mm and 0.12 x 0.10 inches For 1206 package style, the sizes are 3.0 x 1.5 mm and 0. 0.12 x 0.06 inches
What are the three figure codes for SMT resistors?
A three figure SMT resistor coding system is the one that is normally used for standard tolerance resistors. As the name indicates this SMD resistor marking system uses three figures. The first two figures in the code indicate the significant figures, and the third is a multiplier.
