LT7330001K0JTG Datasheet, PDF (1/1 Pages) Tyco Electronics – Temperature Sensing Chip Resistor (P.T.C. Thermistor)

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.

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