<p>PROBLEM TO BE SOLVED: To provide a film resistor excellent in overload characteristics, when a rectangular waveform energization is applied. SOLUTION: A film resistor is equipped with a resistive film 12, formed on the surface of a cylindrical insulating base 11 and cap-like metal terminals 13, each mounted on the ends of the insulating base 11 and electrically connected to the resistive film 12. Discontinuous resistance correcting grooves 16 are cut in the resistive film 12, so as to make uncorrected parts 16a located on straight lines extend in the axial direction of the insulating base 11. The space between the resistance correcting grooves 16 in the axial direction of the insulating base 11 is set as long as 0% to 20% of the overlapping length of the adjacent resistance correction grooves 16.</p> |
