Thick Film Chip Attenuator, Surface Mount, Unbalanced π Type
FEATURES
• Single component reduces board space and
component counts - replaces 3 or more
Available
components
• Tolerance matching and temperature tracking
superior to individual components
• Maximum power dissipation: 0.075 W for Available
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
• Surface mount chip attenuator in a resistor array package
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
Note
* This datasheet provides information about parts that are RoHS-compliant and / or parts that are non RoHS-compliant. For example, parts
with lead (Pb) terminations are not RoHS-compliant. Please see the information / tables in this datasheet for details
