Thin Film Resistors on Silicon, User Trimmable
FEATURES
Product may not
be to scale
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 ElectroFilms (EFI) sophisticated thin film equipment and
manufacturing technology. The SC7 and SCBs are 100 %
electrically tested and visually inspected to MIL-STD-883.
• Wire bondable
• Chip sizes
SC7 - 0.030 inches square
SCB - 0.050 inches square
• Resistance range RT: 100 Ω to 20 kΩ for SC7
Resistance range RT: 100 Ω to 50 kΩ for SCB
• Silicon substrate
• Power: 250 or 400 mW capability
• Resistor material: Nichrome
• User trimmable
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
