Abstract
Precision high-voltage resistor comprising a plane substrate of insulating material (1) on which there has been deposited by silk-screening at least one resistive film (3) of approximately rectangular, square or similar shape and a conductive film in the form of two parallel strips (2a, 2b) extending along two opposite edges of the resistive film and constituting terminals electrically connected to one another by said resistive film, the resistive film comprising rectilinear cuts (5a to 5f) made in its thickness, down to the insulating substrate, parallel to said opposite edges from a third edge (6) of the resistive film, characterized in that the rectilinear cuts (5a to 5f) are evenly spaced along the third edge (6) and have lengths that are larger the closer they are to the center of the third edge (6), the ends opposite the third edge (6) of the rectilinear cuts defining from the intersections (8a, 8b) of the third edge (6) with the terminals (2a, 2 b) a contour (7; 9) exhibiting an apex in its center part.
