Electronics Symbols Handbook
This is a reproduction of CIE’s classic Electronics Symbols Handbook. The symbols listed in this handbook were
collected after much research by the Technical Staff of Cleveland Institute of Electronics, Inc. Because the
electronics industry has not adopted a single symbology standard, CIE has included the most frequently used
symbols that represent each component.
The index lists components by general classification. The specific type of component is listed alphabetically
under the general classification.
CIE has attempted to illustrate the most common symbols in use today in the industry. Your handbook has
been designed to serve as a handy reference guide.
