This process ensures the element Characteristics Mechanical remains stable in performance over Seal Cover: Marking Ink Colour: a long life. The LT73 is equally suited to temperature compensation or thermal protection when the appropriate electronics. This range of sensors are finished in a tough epoxy seal and are available on tape for high speed auto placement. Key Features Stable Alumina Substrate Solvent Resistant Coating Wide Value Range Excellent Linearity TCR (ppm/C) 60 100 50 80 08 05 Small Size Stocked in 3900ppm/C Other TCR's Available to Order Supplied on Tape and Reel Custom Design Enquiries Welcome The washing process is very important to ensure long term reliability because ionic impurity from flux may cause electrolytic corrosion of the metal film.
