So there's an E192 series for 0.5% components (which is the furthest you can extend the scheme without needing yet a fourth digit) and alternate subsets of it form the E96 (1%) and E48 (2%) series; but some of the E24 values, including that of the 39.0kΩ 1% resistor shown above, are not included in the E192 series. Here is the E96 series; I'll Voltage Divider Calculator. A voltage divider circuit is a very common circuit that takes a higher voltage and converts it to a lower one by using a pair of resistors. The formula for calculating the output voltage is based on Ohms Law and is shown below. R 1 is the resistance of the 1st resistor, measured in Ohms (Ω). E24 (5%) and E96 (1%) Standard Values The two most common E-values for resistors are E24 (24 values per decade) and E96 (96 values per decade). E24 values are typically associated with 5% tolerance, though E24 values are generally offered in 1% and even tighter tolerance such as 0.5%, 0.25% and 0.1% as well. E96 values are typically associated This helps the supplier with stocking different values. Resistors produced by different manufacturers are compatible for the same designs because of the use of standard values. Standard Resistor Value Series and Tolerances. The standard E3, E6, E12, E24, E48 and E96 resistor values are listed below.
