Three characteristics of PTC（二）

Voltage-current characteristics

Referred to as volt-ampere characteristics. It refers to the relationship between the voltage applied to the two terminals of the thermistor and the current under steady-state conditions that reach thermal equilibrium in still air at 25°C, that is, the voltage-current characteristics of the PTC components in the actual working state. The maximum voltage of the component under non-destructive conditions can be obtained from the volt-ampere characteristics. Based on this feature, it can be used for constant temperature heating and home appliance heating.
