How to calculate the value of an SMD resistor. Most chip resistors are marked with a 3-digit or 4-digit code -- the numerical equivalent of the familiar color code for through-hole components. Recently, a new coding system (the EIA-96) has appeared on precision SMDs.
Kalkulator oznaczeń rezystorów do montażu powierzchniowego (SMD) pozwala określić wartość rezystancji na podstawie oznaczenia umieszczonego na rezystorze. Wybierz format kodu: trzycyfrowy EIA, czterocyfrowy EIA lub EIA-96.
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.
Higher precision resistors, combined with the decreasing sizes of resistors, have created the need to have a new, more compact marking for SMD resistors. Therefore the EIA-96 marking system has been created. It is based on the E96-series, thus aimed at resistors with 1% tolerance.
This surface mount resistor value calculator finds the resistance value for resistors marked in the traditional and EIA-96 marking method.
There are three main coding systems used to indicate the resistance value of SMD resistors: the 3-digit code system, the 4-digit code system, and the EIA-96 code system. Once the code is identified, you can use an SMD resistor code calculator to determine the resistor’s value.
