CZA
Vishay Dale
Surface Mount Chip Resistor Attenuator
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
