NTC thermistors

Thermistors have a negative temperature coefficient (TK) and are therefore often called NTC thermistors (NTC = Negative Temperature Coefficient). They consist of mixtures of ceramic materials which determine their properties depending on their composition. Resistance values from a few ohms to a few megaohms and wide operating temperature ranges from -50°C … 500°C are possible. If the ambient temperature of the thermistor changes, the resistance value drops. This behavior can be used, for example, for the purpose of temperature detection or temperature compensation.
