Vishay Dale
Thick Film Chip Resistor Attenuator, Surface Mount
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 W for
CZA06S; 0.040 W for CZA04S
•Consult factory for extended values,
non-standard tolerances, impedance matching
and other attenuation values
•Frequency range: DC to 3 GHz
•Compliant to RoHS directive 2002/95/EC
Note
• Power rating depends on the maximum temperature at the solder point, the component placement density and the substrate material.
* Pb containing terminations are not RoHS compliant, excemptions may apply
