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. 

## **Characteristics - Mechanical** 

|**Seal Cover:**|Orange|

|**Marking Ink Colour:**|Black|



## **Characteristics - Cleaning** 

|The washing process is very important to ensure long term reliability because ionic impurity from flux may<br>cause electrolytic corrosion of the metal film.|
