Resistor, constructed as a surface-mounted device, and method for its production, as well as a printed circuit board having such a resistor

摘要

A resistor, constructed as a surface-mounted device, contains as resistive track (15) a film of a resistive alloy on two electrically isolated carrier board elements (10A, 10B), which are made of copper, are designed as contact elements which can be soldered onto the connecting leads of a printed circuit board and, by this means, ensure good heat dissipation into the printed circuit board. To produce such resistors, a resistive film, sufficient for a multiplicity of individual resistors, is bonded onto a copper sheet of corresponding size and the laminate formed by this means is divided into the individual resistors only after production of the individual resistive tracks and their electrical connection to the copper sheet and after production of the gaps (11) between the board elements (10A; 10B).
