SC7, SCB
Vishay Electro-Films
Thin Film Resistors on Silicon, User Trimmable
FEATURES
• Wire bondable
• Chip sizes
Product may not
be to scale
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
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.
• 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:
• Amplifiers
• Oscillators
• Attenuators
• Couplers
• Filters
Recommended for hermetic environments where die is not exposed to moisture
