Vishay Electro-Films
High TC Thin Film Resistors
FEATURES
• Small chip size
0.020 x 0.020 inch - Format A
0.030 x 0.030 inch - Format B
Product may not
be to scale
• Silicon substrate
• Large change in resistance over temperature
The RT resistor chip series offers high TC for special
temperature sensing applications.
• Standard resistance ranges: 51Ω to 24kΩ - Format A
51Ω to 51kΩ - Format B
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.
APPLICATIONS
Vishay EFI RT chip resistors provide high TCR for circuit temperature compensation and are ideally suited for prototyping.
Typical application areas are:
• Amplifiers
• Oscillators
• Attenuators
• Couplers
• Filters
