Standard Eia Decade Resistor Values

- December 04, 2018

The values in any decade can be derived by merely dividing or multiplying the table entries by powers of 10. As an example 133 can represent w 133 w 133 kw 133 kw 133 kw 133 mw.

As you can see in the chart e24 values are nicely spaced between 100 and 1k ohms.

Standard eia decade resistor values. E3 has three resistors in each decade e6 has six e12 has twelve and so forth. Standard resistor calculator this calculator will select the closest standard resistor value from 1 5 or 10 standard eia values calculates the error and prints out a table of the standard values for the given tolerance. Below 100 ohms or above 1k the series simply repeats.

Tom brannon created date. The different sets of standard resistor values are known by their e series numbers. The series are as follows.

The number following the e specifies the number of logarithmic steps per decade. The 120 ohm resistor has a value ranging between 110 and 130 ohms. The most basic series within the e range is the e3 series which has just three values.

The eia e series specify the preferred values for various tolerances. Standard resistance values are obtained from the decade table by multiplying by powers of 10. 1 22 and 47.

The values in any decade can be derived by merely dividing or multiplying the table entries by powers of 10. Standard decade resistance values the following table lists four established number series which ar e used as preferred values in electronic design. The table below is normalized for the decade between 100 and 1000.

Following this logic the preferred values for 10 tolerance resistors between 100. The next reasonable value is 120 ohms because the 100 ohm resistor with a 10 tolerance is expected to have a value somewhere between 90 and 110 ohms. The name e24 comes from the fact that there are 24 values per decade of resistance.

E6 20 tolerance e12 10 tolerance e24 5 tolerance and usually 2 tolerance e48 2 tolerance. Standard value decade for 1 resistors author. Standard eia decade values the electronic industries association eia and then statued by iec publication 60063 specify standard values for resistors sometimes referred to as the preferred value system.

Other eia standards define the values for other tolerance ranges. The table below is normalized for the decade between 100 and 1000. Each series is shown under an associated value of tolerance.

Standard resistance values for the 10 to 100 decade also usable in decade multiples or sub multiples e192 e96 e24 e12 e6 e192 e96 e24 e12 e6 e192 e96 e24 e12 e6 e192 e96 e24 e12 e6 e192 e96 e24 e12 e6.
