4-PIN CIRCUIT
FEATURES
• Single component reduces board space and component counts - replaces 3 or
more components
• Tolerance matching and temperature tracking superior to individual components
• Maximum power dissipation: 75 milliwatts for CZA06S; 40 milliwatts for CZA04S
• Consult factory for extended values, non-standard tolerances, impedance
matching and other attenuation values
• Frequency range: DC to 3GHz
Surface Mount Chip Resistor Attenuator
•Power rating depends on the maximum temperature at the solder point, the component placement density and the substrate material
