Resistance range: 100
Ω
to 50 kΩ
•
Resistor material: Nichrome
•
Oxidized silicon substrate for good power dissipation
•
400 mW capability
•
User trimmable
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.
APPLICATIONS
Vishay EFI SC3 chip resistors have excellent power dissipation capability and are ideally suited for prototyping.
Typical application areas are:
•
Amplifiers
•
Couplers
•
Oscillators
•
Filters
•
Attenuators
Recommended for hermetic environments where die is not exposed to moisture.
