SC3
Vishay Electro-Films
NiCr Thin Film, Top-Contact Resistor
FEATURES
• Wire bondable
• Small single chip size: 0.050 inches square
• Resistance range: 100 Ω to 50 kΩ
• Resistor material: Nichrome
• Oxidized silicon substrate for good power dissipation
• 400 mW capability
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.
• User trimmable
The SC3’s are manufactured using Vishay Electro-Films
(EFI) sophisticated thin film equipment and manufacturing
technology. The SC3s 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.
