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
