E series of preferred numbers – Wikipedia

Also, the E series is used for 0. Commons category link is on Wikidata Commons category link is on Wikidata using P Retrieved from ” https: The two main differences between each major group is the number of significant digits 2 digits for E3 to E24, 3 digits for E48 to E and different rounding rules.

The E3 series is defined as a series of the numbers 1. It should be noted that some values in the E24 series don’t exist in E48 to E series. uec


Archived PDF from the original on Currently, most electrolytic capacitors are manufactured with values in the E6 or E12 series, thus E3 series is likely obsolete. World War II iex production was a major influence for establishing common standards across many industries. In the early 20th centurycapacitor previously called condenser [1] [2] and resistor [3] [4] value increments were different than today.

Other types of electrical components are either specified by the Renard series for example fuses or are defined in relevant product standards for example IEC for 60063.

Later, the post—World War II baby boom and the invention of the transistor kicked off demand for consumer electronics goods during the s.


List of International Electrotechnical Commission standards. Archived from the original on As transistor radio production migrated towards Jec during the s, it was 6063 for the electronic industry to have international standards. Over time, 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 By using this site, you agree to the Terms of Use and Privacy Policy.

If a manufacturer sold resistors with E3 series values in a range of 1 ohm to 10 megohms, then the available resistance values would be: From Wikipedia, the free encyclopedia.
