There are also E12, E24, E48, E96 and E192 series for components of progressively finer resolution, with 12, 24, 48 are a code that indicates one of the 96 "positions" in the standard E96 series of 1% resistor values. The uppercase letter is a code that indicates a power of ten multiplier. For example, the marking "01C" represents 10 kOhm
Resistor color code examples E12 series resistors. In the E12 series each succeeding resistor falls within the -/+ 10 % of the previous value. Until fairly recently, 10% tolerance resistors were the norm, but today, 5% (E24) resistors seem to be the most commonly used. They still can be found in vintage radios, old amplifiers, etc., but the price of a 5% resistor is low enough to be the
Fig. 2.2.1 shows how these tolerance ranges are used in the E12 series of resistors to cover (almost) all possible values of resistance between 10Ω and 100Ω. 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
