Inductors, Resistors, Capacitors, etc... have standard values based largely on the equation
where m is an ESeries value and n is a positive integer less than m.
Each orderofmagnitude is logarithmically broken into a set number of values. For E24 series, those values are 1.0, 1.1, 1.2, 1.3, 1.5, 1.6, 1.8, 2.0, 2.2, 2.4, 2.6, 2.9, 3.2, 3.5, 3.8, 4.2, 4.6, 5.1, 5.6, 6.2, 6.8, 7.5, 8.3, 9.1
