The E3 series is defined as a series of the numbers 1. Commons category link is on 660063 Commons category link is on Wikidata using P 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 wires.
Views Read Edit View history. Retrieved from ” https: This page was last edited on 1 Novemberat Currently, most electrolytic capacitors are manufactured with values in the E6 or E12 series, thus E3 series is likely obsolete. 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. 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.

Also, the E series is used for 0. 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.
Archived from the original on Wikimedia Commons has media related to E12 values. 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 From Wikipedia, the free encyclopedia.
Archived PDF from the original on In the early 20th centurycapacitor previously called condenser   and resistor   value increments were different than today.
It should be noted that iwc values in the E24 series don’t exist in E48 to E series. In other projects Wikimedia Commons. World War II military production was a major influence for establishing common standards across many industries.
