Como habreis visto, la peculiaridad de las series, es que la serie siguiente a cada una, tiene unos valores mas presisos entre cada tipo, empezando por la E6. Es decir mientras que la E6 va desde 1 ohm, a 1.5 ohm, la serie E12, tiene 1 ohm y 1.2 ohm antes de llegar a 1.5 ohm.

Tambien decir quelas series E24 y E48, se utilizan para aplicaciones que requieren una precision nanometrica como pueden ser material de laboratorio o de medicina, en donde el mas minimo microohmio puede llevar al traste a cualquier operacion o investigacion.
