Vishay Electro-Films
Thin Film 0202 Size Resistor on Alumina
CHIP
RESISTORS
The SFC series resistor chips offer a combination of low
shunt capacitance and small size. The SFCs tantalum nitride
resistor material offers excellent resistance to high moisture
environments.
The SFCs are manufactured using Vishay Electro-Films
(EFI) sophisticated thin film equipment and manufacturing
technology.
The SFCs are 100 % electrically tested and visually
inspected to MIL-STD-883.
FEATURES
•Wire bondable
•Small size: 0.020 inches square
•Resistance range: 10 Ω to 10 kΩ
•Alumina substrate
•Low shunt capacitance: < 0.2 pF
•Resistor material: Tantalum nitride
•Moisture resistant
APPLICATIONS
Vishay EFI SFC chip resistors provide excellent high-frequency response and are ideally suited for prototyping.
Typical application areas are:
•Amplifiers
•Oscillators
•Attenuators
•Couplers
•Filters
