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: 0.075 Watts for CZA06S; 0.040 Watts for CZA04S
• Consult factory for extended values, non-standard tolerances,
impedance matching and other attenuation values
• Frequency range: DC to 3GHz
• Lead (Pb)-Free Version is RoHS Compliant
Surface Mount Chip Resistor Attenuator
•Power rating depends on the maximum temperature at the solder point, the component placement density and the substrate material
