 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.
