Product Highlight

  • VSWR: 1.2
  • Operating Frequency: 0 to 3 GHz
  • Operating Temp Range: -55 to +125 °C
The CZA thick film attenuator, used to improve the accuracy and speed of RF input signal circuits like those in drug infusion devices, replaces three 0402s with a single chip. Other applications are, RF signal attenuation, Cell phones, Mobile and hand-held equipment and Power “step-down” applications.

This is a series of surface mount thick film chip attenuators that offers the industry's widest impedance and attenuation range for this device type. The CZA chip attenuators provide improved attenuation in a single device as compared to three or more discrete resistors. Additional benefits include lower overall component costs, board space and weight savings for the manufacture of communications, automotive and consumer
electronic products.

Designed to provide a specific impedance and attenuation in an unbalanced p type configuration, the CZA series is used for signal attenuation in the RF section in cell phones and wireless information appliances, and in a range of applications in automotive and consumer entertainment systems. The range of impedance options (50Ω / 75Ω / 100Ω /300Ω / 600Ω) and an attenuation range from 1dB to 20dB is the industry's broadest. Both 40mW (CZA04S) and 75mW (CZA06S) maximum input power options are available.

Electrical and environmental performances are superior compared to discrete thick film resistor chips. Attenuation tolerance of ±0.3dB to ±0.5dB, temperature coefficient of resistance is ±100ppm/ºC and a maximum voltage standing wave ratio (VSWR) of 1.2 results in improved signal quality.

The CZA04S chip attenuator is a surface mount device measuring 0.039" x 0.039" (1mm x 1mm), while the CZA06S measures 0.063" x 0.059" (1.6mm x 1.5mm). The component height is 0.014" (0.35mm) and 0.020" (0.5mm) respectively.


  • 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: 0.075W for CZA06S; 0.040W for CZA04S
  • Consult factory for extended values, nonstandard tolerances, impedance matching and other attenuation values
  • Frequency range: DC to 3GHz
  • Lead (Pb)-free version is RoHS-compliant
