      NTC thermal resistance is a thermistor that negatives the temperature coefficient. It is a sensitive electronic component. The resistance value of NTC (NEGATIVE TEMPERATURARATURATURATURINT) thermistor is that the resistance value characteristics of thermoltic resistance are reduced as the temperature rises, which decreases. It is usually made of manganese, copper, cobalt, iron, nickel, zinc and other two or more transitional metal oxides. It is mixed with a certain ratio and is prepared by ceramic crafts.

      Electronic components usually have a certain temperature coefficient. Its output signal will drift with temperature changes. It is called "temperature drift". In order This measure is called temperature compensation.

      Among some electrical appliances with very high accuracy, especially precision instruments, there are many components made of metal wire, and metal generally has a positive temperature coefficient. At this time Compensation for resistance, that is, NTC thermistor. One positive and negative can offset errors caused by temperature changes and improve accuracy.
