The minimum resistance of the PTC device is the lowest value of the R-T curve that the thermistor can achieve. It is the point just below the transition temperature The resistance versus temperature graph shows how a. PTC reacts to temperature changes. Tb = transition temperature.

For a positive or PTC thermistor, as temperatures increase
PTC stands for „Positive Temperature Coefficient“. PTC thermistors are resistors with a positive temperature coefficient, which means that the resistance increases with increasing temperature. PTC thermistors are divided into two groups, based on the materials used, their structure and the manufacturing process. Class Pt RTD THERMISTOR Response* PTC PTC NTC NTC NTC NTC NTC NTC NTC NTC NTC NTC *PTC: Positive Temperature Coefficient *NTC: Negative Temperature Coefficient STANDARD RTD AND THERMISTOR VALUES (Ohms Ω) °C °F 100 Ohm 1000 Ohm 2.2k 3k 10k Type 2 10k Type 3 10k Dale 10k 3A221 10k “G” US 20k 20k “D Positive Temperature Coefficient Thermistor - PTC Thermistors are an electronic component where the resistance remains almost constant near room temperatures. However, when the temperature exceeds a constant temperature, the resistance suddenly increases. The second group is the switching type PTC thermistor. This type of PTC thermistors is widely used in PTC heaters, sensors etc. Polymer PTC thermistors, made of a special plastic, are also in this second group, often used as resettable fuses. The switching type PTC thermistor has a highly nonlinear resistance-temperature curve.
