WebLeaded thin film resistor • long-term operation Hence, one single resistor product proves to be suitable for two completely different classes of application just by choice of the operating mode and the individually permitted power dissipation. Loaded with P70, for a film temperature at 125 °C Load duration 1000 h 8000 h 225 000 h WebA failure mode has been observed in metal film resistors when they are subjected to single shot high voltage pulses. The conductor fails at a high field point which may be inherent in the design or may be due to manufacturing defects. The localised nature of the failure leads to the conclusion that there is a closed moly tuff greaseWebMost mechanical failure modes of thick film resistors are propagated by heat. It is therefore important to understand the heat dissipation properties of the resistor and substrate material. A low power resistor dissipates heat via conduction through its component leads or connections, while a high power resistor dissipates heat through radiation. iain macleod actor
