It should be noted that some values in the E24 series don’t exist in E48 to E series. Views Read Edit View history.
Other types of electrical components are either specified by the Renard series for example fuses or are defined in relevant product standards for example 60603 for wires.

It consists of the E3E6E12E24E48E96 and E series, where the number after the ‘E’ designates the iev of value “steps” in each series. Commons category link is on Wikidata Commons category link is on Wikidata using P 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: This allows easier purchasing migration between different tolerance parts.

Also, the E series is used for 0. Wikimedia Commons has media related to E12 values. Archived PDF from the original on Archived from the original on As transistor radio production migrated towards Japan during the s, it was critical for the electronic industry to have international standards. From Wikipedia, 06063 free encyclopedia. The E3 series is defined as a series of the numbers 1.
The two main differences between each major group is the number of significant digits 2 digits for E3 to E24, 6063 digits for E48 to E and different rounding rules. This page was last edited on 1 Novemberat Retrieved from ” https: List of International Electrotechnical Commission standards. Later, the post—World War II baby 6063 and the invention of the transistor kicked off demand for consumer electronics goods during the s.
Over time, components evolved towards common values, then based on some of these kec conventions, the International Electrotechnical Commission IEC began work on an international standard in World War II military production was a major influence for establishing common standards across many industries. In the early 20th centurycapacitor previously called condenser   and resistor   value increments were different than today.
