Oxidized silicon substrate for good power dissipation
400 mW capability
User trimmable
Product may not be to scale
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- resistors are manufactured using Vishay
Electro-Films (EFI) sophisticated thin film equipment and
manufacturing technology. The SC3- resistors 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
• Oscillators
• Attenuators
• Couplers
• Filters
Recommended for hermetic environments where die is not
exposed to moisture.
