Capacitors (Fixed & Variable)
Surface Mount, Leaded, Arrays

Manufacturers & Services

Compared to resistors, capacitors are the second-most often used discrete electronic component. Inductors would be the third most used. 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 capacitors, from the smallest surface mount chip format to the monster metal can electrolytic capacitors used in power factor correction banks. They make axial lead, radial lead, electrolytic, tantalum, ceramic, fixed, variable, low voltage, high voltage, low ESR, and any other variation capacitors. As always, I ask you to please check with RF Cafe advertisers as your first choice.

Please consider my advertisers first, since they help underwrite the effort.
