Higher power up to 200 mW at 25 °C ( _P_ 25) can be tolerated on uniform layer TFPT0402 5R ## **APPLICATION INFORMATION** When the resistor dissipates power, a temperature rise above the ambient temperature occurs, dependent 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 Management in Surface-Mounted 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 125 °C of 100R x 1.463 x 1.03 x 1.01 = 152.2  . ## **RATIO** _**R**_ **T/** _**R**_ **25** **==> picture [238 x 369] intentionally omitted <==** **----- Start of picture text -----**
