NTC thermistors
Positive temperature coefficient (PTC) thermistors have a negative temperature coefficient (TC) and are therefore often referred to as NTC thermistors (NTC = Negative Temperature Coefficient). They consist of mixtures of ceramic materials, the composition of which determines their properties. Resistance values ranging from a few ohms to several megaohms and wide operating temperature ranges from -50°C to +500°C are possible. If the ambient temperature of the PTC thermistor changes, its resistance decreases. This behavior can be utilized, for example, for temperature sensing or temperature compensation.
