Q-Max / ULTRA Q-Max
Technologies, Inc
RF/ Microwave Porcelain Multi-Layer Capacitors (MLC)
The Q-Max/Ultra Q-Max series of porcelain and ceramic dielectric capacitors are ideally suited for
RF/Microwave frequency application from 10MHz to 4.2 GHz. The combination of high density, high purity
dielectric material impervious to moisture, heavy pure palladium internal electrodes and strict statistical
process controls allows Q-Max/Ultra Q-Max MLCs to meet or exceed applicable performance characteristics
of MIL-PRF-55681/4.
These capacitors are suitable solutions for applications
that require:
•
Extremely High Quality Factors
•
Very Low Equivalent Series Resistance
•
Very High Series Resonance
•
High Current Carrying Capabilities
•
Greatest Stability Under Changing Factors
