Capable of sensing heat, temperature sensors are widely used to protect equipment and circuits. NTC thermistors are elements whose resistance falls with an increase temperature, while PTC thermistors display an increase in resistance as temperature rises.
Their characteristic temperature-resistance curves allow them to be used as temperature sensors. NTC thermistors find a wide range of uses since they feature high precision and good thermal response. PTC thermistors are employed in many applications that detect certain temperature levels using extremely simple circuits. Murata thermistors come in chip and lead types.
