E96 Resistor Series Series For Resistors
Those sets are called ' E series', and denoted as E followed by the number of resistors in one decade. This problem comes from the fact that resistors only exists in discrete sets of standard values depending on their tolerance. Other types of electrical componenOne problem with resistive dividers is to find a couple of resistors that will give a required potential division ratio. Although it is theoretically possible to produce components of any value, in practice the need for inventory simplification has led the industry to settle on the E series for resistors, capacitors, inductors, and zener diodes. It consists of the E3, E6, E12, E24, E48, E96 and E192 series, where the number after the 'E' designates the quantity of value 'steps' in each series. The E series is a system of preferred numbers derived for use in electronic components.
Mouser is an authorized distributor for many resistor kit manufacturers including Bourns, KOA, Murata, Ohmite, Susumu, TE Connectivity, Vishay & more. Resistor Kits are available at Mouser Electronics from industry leading manufacturers.

Do not apply a voltage exceeding the rated voltage across any RHOM resistors. Anyway, with only discrete values available it is not trivial to find the pairs of resistors that yield a ratio close to the one you want.performance and reliabillity of the resistor.
EIA Standard Resistor Values by ± Tolerance Move the decimal point to achieve the actual value desired. Simple! In addition the tolerance of the voltage divider is also calculated 1, which is a unique feature of this tool.E6 E12 E24 E48 E96 E6 E12 E24 E48 E96 E6 E12 E24 E48 E96. Products (164) Datasheets (75)Type in the I/O voltages or the desired division ratio, select the E series you are working with and you will get a list of the best 12 matches.

The requested ratio should obviously be between zero and one. In other words: small ratios are bad for tolerance, large ratios are good. On the other hand, a high ratio of 0.988 will result in a much smaller tolerance (~0.13%).
If this option is selected then values of E24 not present in the selected series will also be used. E24 values can be found in higher precision than just 5%. The ratio input is ignored and recalculated from V in and V out if the latter two inputs are provided. Values over 1 are considered as "division factors" and will be automatically inverted. Math is powerful, be careful. Like the destruction of the universe.
When custom values are used, the best 5 resistor pairs not in the top 12 and which include at least one of your custom values will also be shown. This can be used to highlight specific / preferred values without actually adding new custom values. Custom values that are part of the selected E series will still be highlighted (in light blue) like other custom values. When combined with an E series, custom values are supposed to have the same tolerance as the E series. Ratio tolerances are not calculated when only custom values are used. For example: 270 ohm is part of E24 but not of E96 ticking this option with the E96 series will add 270 ohm (among others) to the E96 list of possible resistor values.
Maximum input for the ADC was 10V. It was a 10bit ADC fed by the output of a resisitve divider (factor 1/10). I did this small program for a problem with an analog/digital converter (ADC).
It should be noted that these seemingly very accurate results will not be seen in real life due to the tolerance of the resistors which result in a ~0.7% tolerance in the ratio of the divider (E192, 0.5%). Similarly, 1/pi can be estimated with 4 significant digits using 390 and 835 ohm resitors. Numberphile time: you can reach the ratio of pi/10 with 6 decimals accuracy by using 284 and 620 ohm resistors (E192 with extra E24 values). Which, as it turns out, can be obtained almost exactly by using two simple 3K9 and 36K resistors. So instead of a 1/10 divider I was now looking for 1/10.23 = 0.097752. To have it equal to 10mv I wanted to add the 1000/1023 factor in the upstream divider.
