What is an E12 value resistor?
The E12 series has 12 values for each multiple of ten; it is used for resistors with 10% tolerance. The values are 10, 12, 15, 18, 22, 27, 33, 39, 47, 56, 68, 82, then it continues 100, 120, 150 etc.
What is the tolerance of an E12 series resistor and by which letter code is it indicated?
Standard Resistor Value Series and Tolerances
| E Series | Tolerance (SIG FIGS) | # of Values in Each Decade |
|---|---|---|
| E3 | 36%* | 3 |
| E6 | 20% | 6 |
| E12 | 10% | 12 |
| E24 | 5% | 24 |
What is the E24 series?
E24 values (5% tolerance) 1.0, 1.1, 1.2, 1.3, 1.5, 1.6, 1.8, 2.0, 2.2, 2.4, 2.7, 3.0, 3.3, 3.6, 3.9, 4.3, 4.7, 5.1, 5.6, 6.2, 6.8, 7.5, 8.2, 9.1.
What is the E12 range?
The E12 series is so called because 12 ‘Preferred Values’ of resistor, each having a tolerance range of +/-10% covers all values from 10Ω to 100Ω. This range of values is called a decade, and the next higher range (decade) in the E12 series covers values between 90Ω (100Ω -10%) and 902Ω (820Ω +10%) and so on.
What are standard resistors?
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.
Are all 10k resistors the same?
A 10k ohm resistor has 4 color bands: brown, black, orange, and gold for 5% tolerance, respectively. A 1k ohm resistor has 4 color bands: brown, black, red, and gold for 5% tolerance, respectively.
What are E series resistors?
E series of standard resistor values. The standard resistor values are organised into a set of series of values known as the E-series. 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.
What is E6 series?
E6 series (preferred numbers), a series of standardized resistor and capacitor values.
What is standard resistor?
What do you mean By E12 resistor?
The E12 series is so called because 12 ‘Preferred Values’ of resistor, each having a tolerance range of +/-10% covers all values from 10Ω to 100Ω. This range of values is called a decade, and the next higher range (decade) in the E12 series covers values between 90Ω (100Ω -10%) and 902Ω (820Ω +10%) and so on.
What is the standard value of a resistor?
Typical resistor values lie in the range from 100 &OHgr to 10 k&OHgr with a matching tolerance of ±0.2% and a temperature coefficient of resistance of ±10 to ±200 ppm/°C. Diffused resistors are based upon the same fabrication geometry and techniques used to produce the active transistors on the silicon chip or die.
What is a standard resistor?
A standard resistor is a resistor which is precise enough in value and stable enough in temperature coefficient to be used as a calibration standard. Used in metrology labs to calibrate ohmmeters , resistance bridges, etc.
