# What is an E12 value resistor?

## 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?

The E12 series has 12 values for each multiple of ten, it is used for resistors with 10% tolerance.

What are preferred values?

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 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 is the E24 resistor series?

The different sets of standard resistor values are known by their E-series numbers: E6 has six resistance values in each decimal interval, E12 has twelve, E24 has twenty-four and so forth.

### What is resistor preferred value?

Resistors are available in a number of standard ranges, often called ‘preferred values’ These ranges, or series, are set out by the Electronic Industries Association (EIA), and are E3, E6, E12, E24, E48, E96 and E192. The number after the ‘E’ denotes the number of values the series contains per decade.

What is preferred resistor value?

Preferred Values or E-series Because of this, all resistors with a tolerance of 10% overlap. The series looks as follows: 1– 1.2 – 1.5 – 1.8 – 2.2 – 2.7 – 3.3 – 3.9 – 4.7 – 5.6 – 6.8 – 8.2 – 10 etc. All of these values can be powers of ten (1.2 – 12 – 120, etc.). E192 0.5% (also used for resistors with 0.25% and 0.1%).

What is E12 series?

#### 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.

#### What is the tolerance of an E6 resistor?

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

Can a pull up resistor be kept in the E3 series?

One example where values can be kept within the E3 series occurs with digital design where a pull up or pull down resistor is needed. The exact value is of little is of little consequence and the value can be maintained within the E3 series.

What is the EIA standard resistor value series?

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.
