Abstract

See full text

An annular ceramic washer has inner and outer cylindrical surfaces, first and second annular surfaces, and a winding path thick film resistor located on the inner surface. Metal washers are preferably brazed to the end ring surfaces. The annular ceramic washer is useful in vacuum tube applications in establishing a voltage on a target utilizing the voltage of an electrode coupled to the winding path thick film resistor.
