Identifying the manufacturers' type number of an SMD device from the package code can be a difficult task, involving combing through many different databooks. This HTML book is designed to provide an easy means of device identification.
Here you can download our free SMD code book that shows SMD marking codes for almost every surface-mount device available on the market. To identify a particular device, first identify the package style and note the ID code printed on the device. SMD code book (PDF download)
PDF Version. Chapter 2 - Resistor Standards and Codes. What are SMD Resistors? SMD resistors on a printed circuit board. Image used courtesy of TE Connectivity. SMD stands for Surface Mounted Device. An SMD is any electronic component that is made for use with SMT, or Surface Mount Technology.
Welcome to the SMD Codebook! The SMD Codebook is a reference for Surface Mount Device semiconductor device codes, equivalents and connections.. SMD Codebook Codes beginning with '0' be sure to check the 'O' (letter O) table as well Code Device Manf Base Package Leaded Equivalent/Data 0 2SC3603 Nec CX SOT173 Npn RF fT 7GHz
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.
These tiny chips are marked with three (3) or four (4) digit codes which are called SMD Resistor codes to indicate their resistance values. Below are some given roles which help to know the exact value of an SMD resistor by seeing the printed character codes on those tiny chips.
The document lists the EIA-96 code designations for surface mount resistors ranging from 1 ohm to 97.6 Mohms. It includes a table with the code for each resistor value in increments of hundredths of an ohm up to hundreds of ohms, and then increments of kilohms up to tens of megohms.
