The E series is a system of preferred numbers (also called preferred values) derived for use in electronic components. It consists of the E3, E6, E12, E24, E48, E96 and E192 series, [1] where the number after the 'E' designates the quantity of logarithmic value "steps" per decade.

E12 Series. The E12 series has twelve values or steps per decade and hence provides better precision as compared to both the E3 and E6 series. The values per decade in the E12 series are – 1.0, 1.2, 1.5, 1.8, 2.2, 2.7, 3.3, 3.9, 4.7, 5.6, 6.8, and 8.2. It’s widely used in applications where moderate precision is required.

2021年11月26日 · 电阻的标称阻值分为e6、e12、e24、e48、e96、e192六大系列，分别适用于允许偏差为±20%、±10%、±5%、±2%、±1%和±0.5%的电阻器。 其中E24系列为常用数系，E48、E96、E192系列为高精密电阻数系

E12 series resistors. In the E12 series each succeeding resistor falls within the -/+ 10 % of the previous value. Until fairly recently, 10% tolerance resistors were the norm, but today, 5% (E24) resistors seem to be the most commonly used. They still can be found in vintage radios, old amplifiers, etc., but the price of a 5% resistor is low ...

Explore the E12 series of resistors: their standard values, 10% tolerance, color codes, and how they're used in everyday electronics. Find practical tips and comparisons with other resistor series.

Following this logic, the preferred values for 10% tolerance resistors between 100 and 1,000 ohms would be 100, 120, 150, 180, 220, 270, 330 and so on (rounded appropriately); this is the E12 series shown in the table below. The EIA "E" series specify the preferred values for …
