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 …

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 …

A complete guide to reading SMD resistor codes. Learn to identify 3-digit, 4-digit, and the EIA-96 (1% tolerance) code system with charts and examples.

Standard-tolerance SMD resistors use a 3-digit code to mark the resistance value on the part. The first two numbers will indicate the significant digits, and the third will be the multiplier. 'R' is used to …

Aug 9, 2025 · Understand the different coding schemes for SMD resistors: 3-digit, 4-digit, and EIA-96. Learn how to decode values and multipliers, including special notations like “R” and milli-ohm letters. …

Dec 3, 2025 · Surface-mount resistors are compact, cost-efficient, and dominate modern PCB design. However, their small size often leaves little room for full value markings. Misinterpreting a marking-or …

The shape and size of surface mount resistors are standardized with most manufacturers use the JEDEC standards. The size of SMD resistors is indicated by a numerical code, such as 0603.

Jul 4, 2025 · Learn how to read SMD resistor values easily using code chart. Decode 3-digit and 4-digit SMD resistor markings in seconds.

Learn to decode SMD resistor codes with our guide for engineers. Understand markings, tolerance, and identify 0603 & 0805 resistors easily.

This calculator allows you to calculate the nominal value for resistors marked with 3 or 4 characters. The EIA-96 marking is also supported.
