The SC3 series resistor chips on silicon offer a combination
of nichrome stability, wide resistance range and higher
power rating than is available on the same sized ceramic
substrate.
The SC3’s are manufactured using Vishay Electro-Films
(EFI) sophisticated thin film equipment and manufacturing
technology. The SC3s are 100 % electrically tested and
visually inspected to MIL-STD-883.
FEATURES
•Wire bondable
•Small single chip size: 0.050 inches square
•Resistance range: 100 Ω to 50 kΩ
•Resistor material: Nichrome
•Oxidized silicon substrate for good power dissipation
•400 mW capability
•User trimmable
APPLICATIONS
Vishay EFI SC3 chip resistors have excellent power dissipation capability and are ideally suited for prototyping.
Typical application areas are:
•Amplifiers
•Oscillators
•Attenuators
•Couplers
•Filters
Recommended for hermetic environments where die is not exposed to moisture.
