ROHS Circuit Protection Resettable Polyfuse , Practical PPTC Resettable Fuse

Smaller Size Polymer PPTC Thermistor Saves Board Space And Cost Low Resistance​

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.


Features

1 Easy to set up with safety and stability.

2 Smaller size that saves board space and cost.

3 Resettable circuit protection.

4 Fast time-to-trip.

5 Low resistance.
