Abstract

Method for producing class 2 resistors with PTCs, including the following phases: fitting, inside a tube (1) which constitutes the container of the resistor, at least two layers of insulating material (2) in correspondence with the internal surface of said tube; fitting a heating element composed of one or more PTC elements (4) clamped between a pair of diffusers (5) inside said tube, after fitting one or more centring elements; filling the spaces between said heating element and said insulating layer with pulverized magnesium oxide (6); compacting said magnesium oxide; in which the dimensions of the magnesium oxide grains are below 200 microns.
