Abstract

Abstract A viad chip resistor made from an insulative wafer and having a via formed near end of the wafer. Conductive pads surround the vias on both sides of the wafer. A resistive element is formed on one side of the wafer between the vias and is electrically connected to the conductive pads on that side. An array of viad chip resistors, from which said individual viad chip resistors are cut, is also shown.
