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

AD621 and AD620
The AD621 is similar to the AD620, except that the gain resistors for setting gains of 10 and 100 are already integrated on the chip—no external resistors are required. Selecting a gain of 100 require...
