This tiny thin film chip is manufac-

tured 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 compensa-

tion or thermal protection when

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.

The washing process is very important to ensure long term reliability because ionic impurity from flux may

cause electrolytic corrosion of the metal film.
