AC-DC disk resistors made of surface-mount components

Disk resistors are widely used in micropotentiometers up to frequencies in the radio frequency (RF) range. They offer very small AC-DC differences but the permissible power dissipation is quite small. Also the resistance value is poorly defined due to the lack of four-terminal connections. This can be overcome by newly designed disk resistors made of surface mount (smd) components. They are also well suited as AC-DC current shunts for currents up to several amperes.
