Mã điện trở SMD

Designed for electronics engineers, repair technicians, students, and DIY enthusiasts, this website provides a complete and convenient SMD resistor code lookup and calculation tool. Whether you are working with standard 3-digit and 4-digit resistor markings or advanced EIA-96 and EIA-24 precision resistor codes, you can quickly find the corresponding resistance values and specifications, helping save valuable time during circuit design, component identification, and repair work.

With real-time input and automatic decoding features, simply enter the code printed on the resistor to instantly obtain the resistance value, tolerance, multiplier, and related specifications without manually searching through charts or performing complex calculations. The system also includes a built-in resistor calculator for resistance conversion, multiplier analysis, and reverse code lookup, making the entire process faster and more intuitive.

In addition to text and numerical information, the website can instantly generate a simulated SMD resistor image based on the entered code. Users can visually compare the generated marking with actual components, reducing identification errors and improving accuracy. This makes the tool highly practical for electronics repair, component sourcing, and educational purposes.
