ABSTRACT:
A resistor of SMD (Surface Mounted Device) construction includes a film of a resistive alloy as a resistive track on two electrically separated carrier plate elements of copper, which are constructed as contact elements solderable to the terminals of a printed circuit board to thereby ensure good heat dissipation into a printed circuit board. In order to manufacture such resistors, a resistive film sufficient for a plurality of individual resistors is adhered to but electrically isolated from a large copper plate and the laminate formed thereby is split into the individual resistors after producing the individual resistive tracks and their electrical connections to the copper plate and after producing gaps between the plate elements for each track.
