Compared to inductors and capacitors, resistors are the 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 resistors, from the smallest 0201 surface mount chip format to the monster wire-wound resistors used in high power applications. They make axial lead, radial lead, wire-wound, carbon, fixed, variable (potentiometers), resistor arrays, low voltage, high voltage, low power, high power, and any other variation resistors. As always, I ask you to please check with RF Cafe advertisers as your first choice.
