Termistori wikipedia
WebTermístor (ou termistor) é um semicondutor sensível à temperatura.. Existem basicamente dois tipos de termístores: NTC (do inglês Negative Temperature Coefficient) - termístores cujo coeficiente de variação de resistência com a temperatura é negativo: a resistência diminui com o aumento da temperatura.; PTC (do inglês Positive Temperature … WebTemperature is a physical parameter that describes the average kinetic energy of molecules, it is not a measure of energy itself, but it is proportional to the average kinetic energy of molecules. That means that the hotter molecules are, the more they move and the higher is the temperature.

The word thermistor is a portmanteau of thermal and resistor. Thermistors are divided based on their conduction model. Negative Temperature Coefficient (NTC) … See more Depending on materials used, thermistors are classified into two types: • With NTC thermistors, resistance decreases as temperature rises; usually due to an increase in conduction electrons bumped up by … See more In practical devices, the linear approximation model (above) is accurate only over a limited temperature range. Over wider temperature ranges, a more complex … See more When a current flows through a thermistor, it generates heat, which raises the temperature of the thermistor above that of its environment. If the thermistor is being used to measure … See more The first NTC thermistor was discovered in 1833 by Michael Faraday, who reported on the semiconducting behavior of silver sulfide. … See more Thermistors are typically built by using metal oxides. NTC thermistors are manufactured from oxides of the iron group of metals: e.g. chromium (CrO, Cr2O3), manganese (e.g. MnO), cobalt (CoO), iron (iron oxides), and nickel ( See more NTC (negative temperature coefficient) Many NTC thermistors are made from a pressed disc, rod, plate, bead or cast chip of semiconducting material such as sintered metal See more PTC • As current-limiting devices for circuit protection, as replacements for fuses.
