Higher power up to 200 mW at 25 °C (P25) can be tolerated on uniform layer TFPT0402 5R

APPLICATION INFORMATION

When the resistor dissipates power, a te mperature rise above the ambient tempera ture occurs, depend ent on the thermal resistance of the assembled resistor together with the printed circuit board. The rated dissipation applies only if the permitted film temperature of 150 °C is not exceeded. Please consider the application note “Thermal Mana gement in Surface-Mounte d Resistor Applications” (www.vishay.com/doc?28844 ) for information on the general nature of thermal resistance. The TFPT0402 uniform layer linear thermistor with low resistance value can be used as an air-flow sensor in a controlled power mode where nickel film temperature changes can be related to air-flow speed.

For total resistance tolerance, the specific R 25 tolerance needs to be multiplied with the ratio tolerance, for example a 100R 1 % at 25 °C will have a maximum resistance at RATIO RT/R25 POWER DERATING Note
