Power applied at maximum temperature should not let increase the film temperature by more than 1 K (1 °C) > (4) Valid for sensor element only in low dissipative mode. For dissipative mounting, please refer to APPLICATION INFORMATION > (5) Rated continuous working voltage is maximum working voltage or — _P_ 70 x _R_ whichever is less ## **APPLICATION INFORMATION** When the TFPT dissipates power, a temperature rise above the ambient temperature occurs, dependent on the thermal resistance of the assembled thermistor together with the mounting substrate. The (de)-rated power dissipation applies only if the long term permitted film temperature of 150 °C is not exceeded by more than 1 °C. Typically the thermal resistance (RthFA) of a FR4 mounted TFPT0603 is around 250 K/W. 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.

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 Ω. ## **RATIO** _**R**_ **T/** _**R**_ **25** ## **TCR TYPICAL VALUE** **==> picture [209 x 357] intentionally omitted <==** **----- Start of picture text -----**
