PTC thermistor

PTC thermistor

PTC resistors belong to the group of thermistors. They are used s variable resistors based on temperature. At low temperatures they conduct current better than at high temperatures. Their electrical resistance increases as the temperature increases.. Due to these characteristics they are used for compensation for fluctuations in temperature, and reducing the risk of local overheating in devices and circuits. They are therefore installed for instance in electric motors or machine tools. Because they are compact, they are very suitable for incorporation in small objects.
