Power: 250 or 400 mW capability
Resistor material: Nichrome
User trimmable
The SC7 and SCB series resistor chips offer a combination
of nichrome user trimmability as a single resistor or as a ratio
trim while maintaining the excellent TCR tracking
characteristics of two resistors on the same chip.
The SC7 and SCBs are manufactured using Vishay Electro-
Films (EFI) sophisticated thin film equipment and
manufacturing technology. The SC7 and SCBs are 100 %
electrically tested and visually inspected to MIL-STD-883.
APPLICATIONS
Vishay EFI SC7 and SCB chip resistors have excellent power dissipation capability and are ideally suited for prototyping.
Typical application areas are:
Couplers
Amplifiers
Filters
Oscillators
Attenuators
Recommended for hermetic environments where die is not exposed to moisture
