There are far too many manufacturers for me to keep a comprehensive list, but here are some links to sites that have done just that:
- EE Hotsheet
A comprehensive listing of all sorts of electronic components, including semiconductors, resistors, capacitors, inductors, optoelectronics, relays, switches, and more. A single page contains all of the most-used electronic links, all in one place.
With access to datasheets for semiconductors, especially for obsolete parts, ChipDocs provides design engineers with information thay need for designing a new or repairing an existing products. Includes a part number decoder, IC logo finder, and IC manufacturer links.
Electronics Web Portal. Includes parts search-engine, parts compare tools, datasheets download, technical information and other powerful tools for engineers, developers and hardware labs.
- Components Bazaar
Information about manufacturers, dealers, and distributors of electronic components. Hosts more than 2000 product profile including ICs, transistors, capacitors, resistors, diodes, active components, passive components, electromechanical components, switches, connectors, circuit protection devices, and much more.
- Datasheet Locator
A free electronic engineering tool enabling user to locate product datasheets from hundreds of electronic component manufacturers worldwide.
A directory of electronic design resources. Of particular interest is their semiconductor search feature.
A gateway to information on thousands of component manufacturers, distributors, reps, and services that support the world-wide high-tech electronics manufacturing industry.
This site has only one purpose: to search distributors for electronic components. Its stable of vendors is somewhat limited, but it performs its search so quickly and reliably that it's still an invaluable resource.
GlobalSpec is the leading specialized search engine for engineers and technical buyers. Find electronic components, data acquisition equipment, test and measurement equipment, industrial computers and embedded computer components, as well as items such as air compressors, electric motors, bearings, bar code scanners and other engineering equipment. GlobalSpec provides a great deal of flexibility in specifying your search criteria to find specific products.
A huge listing of electronic component manufacturers, arranged by product. There are also links to manufacturers of all sorts of other types of components, including mechanical hardware, hydraulics, motors, sensors, video, and much more.
Creators of a Windows-based component locator. This won't necessarily help you select a part, but if you already know what part you want, this will certainly help find it.
A semiconductor search engine and directory of semiconductor manufacturers. Semiseek's objective is to cut through the clutter of the Internet and allow semiconductor professionals to find the services and products they want quickly and efficiently.
A categorized listing of manufacturers of logic, analog, PLDs, micros, memory, resistors, capacitors, connectors, and more.
- Who Makes It?
This site features both a categorized directory of electronic components, and an alphabetical listing of manufacturers.
