Standard EIA Resistor Value Quick Lookup Table

The Electronic Industries Association of the United States has defined a standard resistor value system (in fact, this system also applies to capacitors and inductors). This system was defined in the last century, when resistors were still made of carbon film technology and had very low precision. To understand the resistor value system, take a 10% precision resistor as an example. If the first resistor value is 100Ω, there is no need to make 105Ω, because the resistance precision of 100Ω is 90 to 110Ω, so the second meaningful resistor value is 120Ω, and the resistance precision range is from 110Ω to 130Ω. In this way, the resistor values from 100Ω to 1000Ω are 100, 120, 150, 180, 220, 270, 330, etc. This is the E12 series of resistor values defined by the EIA. The basic resistor values in the following table can be multiplied by the multiplier to obtain other resistance series.
