A brief introduction to the thermal resistance(II)

Time characteristic of electric current: the characteristic of electric current changing with time during the process of applying a resistor to a thermistor. Resistance temperature characteristic: refers to the connection between the zero resistance value of the thermistor and the intrinsic temperature of the resistor under the original voltage. Rated zero power resistance: zero power resistance at 25 C, unless the customer requests another temperature. The resistance of thermistors is the small resistance value corresponding to the series of temperature curves at the normal temperature of 25 degrees, the temperature corresponding to the small resistance.

Switch temperature: when the value of the class jump is increased, the temperature is the switch temperature, that is, the corresponding heat when the resistance rises to 2 times the small resistance value, also called the Curie point. The working voltage of the thermistor is that the thermistor can withstand the working voltage continuously under the ambient temperature. Current of a thermistor: a large current that allows a thermistor to operate at a working voltage. Non action current: the non action current is the rated current or the current, which means that the PTC thermistor does not present a high resistance state of a large current under the specified time and temperature conditions.
