What are the standard values of resistors?
What are the standard values of resistors?
The most common series are:
- E6 20% tolerance.
- E12 10%
- E24 5% (also available with 1%)
- E48 2%
- E96 1%
- E192 0.5% (also used for resistors with 0.25% and 0.1%).
What are nominal resistor values?
Standard resistors have four color bands. Three of the bands tell you the nominal value, which means the value the resistor was designed to have. The fourth band tells you the tolerance of the resistor, which indicates how far off the nominal value the actual resistance could be.
What is E series resistor?
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, where the number after the ‘E’ designates the quantity of value “steps” in each series.
What is a standard resistance?
Standard resistors are very high precision resistors used as a reference to calibrate or verify the accuracy of other resistors in industry or establishments, on lines or production equipment. these are also used to check the accuracy of resistance meters by most manufacturers.
What is E series of standard resistor value?
Resistor E series tables of values

|---|---|---|
| 1.0 | 1.2 | 1.5 |
| 1.8 | 2.2 | 2.7 |
| 3.3 | 3.9 | 4.7 |

What is the function of a standard resistor?
It implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
What are the characteristics of a standard resistance?
1. The value of resistance should not change with time. 2. The value of resistance should almost remain the same with a change in temperature.
What is the function of resistor?
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
What are the EIA standard resistor tolerances?
Summary of EIA Preferred or Standard Resistor value Series E Series Tolerance (Sig Figs) Number of values in each decade E24 5% [normally also available in 2% tolera 24 E48 2% 48 E96 1% 96 E192 0.5%, 0.25% and higher tolerances 192
What is the tolerance of an E3 resistor?
The series are as follows: E3 50% tolerance (no longer used) E6 20% tolerance (now seldom used) E12 10% tolerance E24 5% tolerance E48 2% tolerance E96 1% tolerance E192 0.5, 0.25, 0.1% and higher tolerances
What are the resistor values for the E12 series?
Standard EIA Decade Resistor Values Table. The 120 ohm resistor has a value ranging between 110 and 130 ohms. 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.
Are there metal oxide resistors in the E24 series?
However the E24 series, being a much closer tolerance series is only available in the higher tolerance types. Metal oxide film resistors that are in common use today are available in the E24 series as are several other types.
