A brief introduction to the technical terms of the thermistor

The thermistor has better performance in capacitors, good quality and small appearance, and is suitable for mass production.

Volt ampere characteristic curve: it is stable at 27 centigrade, which is added to the electric potential difference at the lead end of the thermistor and the current under the stable condition of the heat balance; the insulating thermistor is the thermistor of the prescribed insulation and voltage test. Non insulated thermistor: no thermistor condition is required for insulation voltage and insulation resistance test. Initial current: the current that occurs when the circuit switch is running to close. Peak current: peak to peak of the original current.

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.
