**Temperature Sensing Chip Resistor (P.T.C. Thermistor)**
## **Type LT73 Series**
## **Type LT73 Series**
This tiny thin film chip is manufactured by sputtering pure metals onto a high purity alumina base. This process ensures the element remains stable in performance over a long life. The LT73 is equally suited to temperature compensation or thermal protection when incorporated within the appropriate electronics. This range of sensors are finished in a tough epoxy seal and are available on tape for high speed auto placement.
