E series of preferred numbers – Wikipedia

60063, the E series is used for 0. Wikimedia Commons has media related to E12 values. From Wikipedia, the free encyclopedia. This allows easier purchasing migration between different tolerance parts.

In the early 20th centurycapacitor previously called condenser [1] [2] and resistor [3] [4] value increments were different than today. The two main differences between each major ief is the number of significant digits 2 digits for E3 to E24, 3 digits for E48 to E and different rounding rules.


Over 6063, components evolved towards common values, then based on some of these existing conventions, the International Electrotechnical Commission IEC began work on an international standard in As transistor radio production migrated towards Japan during the s, it was critical for the electronic industry to have international standards.

Other 6003 of electrical components are either specified by the Renard series for example fuses or are defined in relevant product standards for example IEC for wires.

Archived from the original on Retrieved from ” https: Currently, most electrolytic capacitors are manufactured with values in the E6 or E12 series, thus E3 series is likely obsolete.
