Inductors, Chokes & Coils(Fixed & Variable)
Surface Mount, Leaded, Arrays

Manufacturers & Services

Compared to resistors and capacitors, inductors are the third-most often used discrete electronic component. Sure, every physical component has a combination of of all three components in the form of parasitics. These companies are the major suppliers of all forms of inductors, from the smallest surface mount chip format to the monster metal can inductors used in power station transformers. They make axial lead, radial lead, wire-wound, printed ceramic, fixed, variable, low current, high current, low Q, high Q, and any other variation inductors.

As always, I ask you to please check with RF Cafe advertisers as your first choice.

NOTICE: Search engines nowadays penalize websites for having many hyperlinks on a web page, so I no longer keep a list of my favorites. Most search engines do a really good job of locating useful data if your search terms are well thought out, so rather than me supposing I know what you are looking for, I have provided this Search box (and one in the upper-left page border) for you to use.
