(4) Zero power or zero dissipation is considered as measuring power max. 1 % of rated power P

(5) Please refer to APPLICATION INFORMATION
(6) Power levels are depending on way of mounting and substrates used. Higher power up to 200 mW at 25 °C (P ) 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.

RATIO FORMULA
RT = R25 x (9.0014 x 10-1 + 3.87235 x 10-3 (°C)-1 x T + 4.86825 x 10-6 (°C)-2 x T2 + 1.37559 x 10-9 (°C)-3 x T3)
T(°C) = 28.54 x (RT/R25)3 - 158.5 x (RT/R25)2 + 474.8 x (RT/R25) - 319.85)

± 0.5 %
At 40 °C, ratio = 1.063 ± 0.5 % (0.005)
so, ratio = 1.058 to 1.068
At 125 °C, ratio = 1.460 ± 3 % (0.044)
so, ratio = 1.416 to 1.504
At intermediate temperatures, the ratios can be gradually
adapted, for example at 105 °C the ratio tolerance will be
± 2.5 %.
For total resistance tolerance, the specific R25 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 .
