Currently, most electrolytic capacitors are manufactured with values in the E6 or E12 series, thus E3 series is likely obsolete. The actual resistance at the top of the tolerance band is 1. If a manufacturer sold resistors with E3 series values in a range of 1 ohm to 10 megohms, then the available resistance values would be: The rationale is simple – select values for components based on the tolerances with which they are able to be manufactured.
E6 E12 E24 E48 E96 E The EIA Electrical Industries Association which is based in North America is one organisation that has adopted the system and as a result the resistor value series are often referred to as the EIA standard resistor values.
However, this is not always the case as can be seen by comparing the E24 and E96 lists. The EIA preferred values or standard resistor values can be summarised in a tabular form to give the different values within each decade. The values in any decade can be derived by merely dividing or multiplying the table entries by powers of The two main differences between each major group is the number of significant digits 2 digits for E3 to E24, 3 digits for E48 to E and different rounding rules.
The different sets of standard resistor values are known by their E-series numbers: It consists of the E3E6E12E24E48E96 and E series, where the number after the ‘E’ designates the quantity of value “steps” in each series.
The E series preferred or standard resistor value ranges are internationally accepted and have been adopted by international standards organisations. The exact value is of little is of little consequence and the value can be maintained within the E3 series. Archived PDF from the original on In the early 20th centurycapacitor previously called condenser   and resistor   value increments were different than today.
Take then a resistor with a value of 1. World War II military production was a major influence for establishing common standards across many industries. Later, the post—World War II baby boom and the invention of the transistor kicked off demand for consumer electronics goods during the s. Retrieved from ” https: Views Read Edit View history. The E6 series resistor values are also widely used within the industry. Current resistor technology enables very close tolerance levels to be achieved, yet there is still a great benefit in using resistors even from the E3 series.

In other projects Wikimedia Commons. This process is followed through for all the values in a decade, creating a set of standard resistor values for each tolerance.
It reduces the number of different types of resistor used in a design and this simplifies purchasing and manufacturing processes. The E3 series is defined as reihr series of the numbers 1. It should be noted that some values in the E24 series don’t exist in E48 to E series. More accurate tolerances are available for some resistors, but these are not as widely available and costs are higher.
Often designs try to keep to the E3 or E6 reihs resistor values, only using those in the E12, E24, E48 or E96 if absolutely necessary.
Standard Resistor Values: E3, E6, E12, E24, E48
The standard resistor values are organised into a set of series of values known as the E-series. E12 Standard Resistor Series 1.
The table below is normalized for the decade between and 1, Archived from the original on Supplier Directory For everything from distribution to test equipment, components and more, our directory covers it.
Resistor E series tables of values Below are the common resistor values. E series of standard resistor values The standard resistor values are organised into a set of series of values known as the E-series.
List of International Electrotechnical Commission standards. Also, the E series is used for 0. Over time, components evolved towards common values, then based on some of these existing conventions, the International Electrotechnical Commission IEC began work on an international standard in The E96 and E series e4 standard resistor values also exist, but their use is much smaller than those in the other ranges given above.
While the “E” preferred value lists are the best way to insure one is stocking the optimum number of values for a given reine, a word of caution is in order with respect to what is actually available in the marketplace and certain real world practices. The different values are spaced such that the top of the tolerance band of one value and the bottom of the tolerance band of the next one do not overlap.
