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
cause electrolytic corrosion of the metal film.| |---| |**Short time Overload:**
