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 standard component in all of today's electronic circuits.

In precision applications, special, more expensive low-tolerance resistors are used with tolerance ratings of 2%, 1% or less.
