MIC

Vishay Electro-Films

Thin Film Microwave Resistor

The MIC resistor chips on alumina are designed with low

shunt capacitance. Most lower value resistor geometrics are

compatible with strip lines, making them ideally suited for

microwave circuits.

These chips are manufactured using Vishay Electro-Films

(EFI) sophisticated Thin Film equipment and manufacturing

technology. The MICs are 100 % electrically tested and

visually inspected to MIL-STD-883.

FEATURES

• Wire bondable

• Small chip size: 0.020 x 0.040 inches

• Microwave resistance range: 20 Ω - 1 kΩ

• Overall resistance range: 2 Ω to 20 kΩ

• Alumina substrate

• Low stray capacitance: < 0.2 pF

• 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 20 W to 1 kW are standard strip line designs for microwave applications
