This paper reports the dependence between the power required to cause destruction and the dimensions of resistive films, i.e. the width and thickness. The dependence has been analysed using destruction phenomenon models which consider the increase of temperature of the resistive films and the films defects. Results show that the power value required to cause destruction rises linearly with the width of the resistor films and is exponentially proportional to the sheet resistance.
