Vishay Electro-Films
Thin Film Microwave Resistor
MICROWAVE
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.
FEATURES
•Wire bondable
•Chip size: 0.050 inches square
•Microwave resistance range: 18 Ω to 500 Ω
•Overall resistance range: 2 Ω to 100 kΩ
•Alumina substrate
•Low stray capacitance: < 0.2 pF
•Power: 200 mW
•Resistor material: Tantalum nitride, self passivating
•Moisture resistant
•High frequency
APPLICATIONS
Vishay EFI MIC chip resistors provide excellent high-frequency response and are ideally suited for prototyping.
Typical application areas are:
•Amplifiers
•Oscillators
•Attenuators
•Couplers
•Filters
Note:
• Only 18 W to 500 W are standard strip line designs for microwave applications
