RESISTORS
The MID resistor chips on alumina are designed for low shunt
capacitance applications with 200 mW power requirements.
These chips are manufactured using Vishay Electro-Films
(EFI) sophisticated Thin Film equipment and manufacturing
technology. The MIDs are 100 % electrically tested and
visually inspected to MIL-STD-883.
APPLICATIONS
Vishay EFI MIC chip resistors provide excellent high-frequency response and are ideally suited for prototyping.
Typical application areas are:
•
Amplifiers
•
Couplers
•
Oscillators
•
Attenuators
•
Filters
