Small Polymer PPTC Thermistor Low Resistance For Automotive Electronics
Smaller Size Polymer PPTC Thermistor Fast Time-To-Trip Easy To Set Up
The resistance-temperature characteristics of the thermistor can be approximately expressed by the following formula: R=R0exp{B(1/T-1/T0)}: R: resistance value at temperature T(K), Ro: temperature T0, ( K) resistance value, B:B value, *T(K)=t(ºC)+273.15. In fact, the B value of the thermistor is not constant, and its variation varies depending on the material composition, and the maximum can even reach 5K/°C. Therefore, when formula 1 is applied in a larger temperature range, there will be a certain error between the measured value and the actual value. Here, if the value of B in Equation 1 is calculated as a function of temperature shown in Equation 2, the error between the measured value and the actual value can be reduced, and it can be considered to be approximately equal.
