Large change in resistance over temperature
The RT resistor chip series offers high TC for special
temperature sensing applications.
These chips are manufactured using Vishay Electro-Films
(EFI) sophisticated thin film equipment and manufacturing
technology. The RTs are 100% electrically tested and
visually inspected to MIL-STD-883.
