ELECTRICAL RESISTORS AND METHODS OF MAKING SAME

摘要

An electrical resistor which is fabricated from traces of resistive material on a substrate of insulating material. The traces are interconnected electrically in series by first links and in parallel by second alternating links, which are connected to different terminals on the substrate. The second links are cut, preferably by laser trimming, so as to select the value of resistance of the resistor by reducing the number of traces connected in parallel and increasing the number of traces connected in series. Where the resistance of each trace is "R", the value of the resistance is adjustable by severing the second links from R/n to nR, where n is the number of traces.
