Abstract
An electric component is disclosed with trimmable complex resistive-capacitive impedance comprising a first resistor layer forming a ground plane, an insulation layer connected thereover and a second resistor layer connected over the insulation layer. The second resistor layer is divided into a plurality of resistor layer portions. The resistor layer has one edge which is attached to a power drive connector and an opposite edge which is step shaped so that the resistor layer portions are varied both in length and in width. The resistor layer portions are selectively connected and disconnected from each other to produce a desired impedance value.
