PCAT0404X-0R5AT-CT

Overview

The PCAT0404X-0R5AT-CT is a surface-mount RF attenuator manufactured by Venkel. It provides an attenuation value of 0.5 dB with a frequency range spanning from 0 Hz to 3 GHz. The component operates at a standard impedance of 50 Ohms and has a maximum power rating of 100 mW. It utilizes a convex package design within the 0404 (1010 Metric) footprint, suitable for high-frequency signal conditioning applications.

Feature Summary

• Provides precise 0.5 dB attenuation for signal level adjustment
• Operates effectively across a wide frequency spectrum up to 3 GHz
• Features a convex package design for enhanced thermal performance

Applications

• RF signal path conditioning
• Impedance matching networks
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'CT' against the manufacturer's current ordering information to ensure compatibility with tape-and-reel packaging requirements. Confirm that the 0404 footprint aligns with the target PCB layout. Cross-reference the 100 mW power rating with system thermal constraints to prevent overheating during operation.

Selection Notes

Select this component when a low attenuation value near 0.5 dB is required for minimal signal loss in 50 Ohm systems. Ensure the operating frequency does not exceed 3 GHz. Consider the convex package profile for assembly compatibility and thermal dissipation needs compared to flat variants.

Part Context

This part belongs to Venkel's PCAT series of chip attenuators. These components are designed for use in radio frequency circuits where precise signal attenuation is necessary. The series offers various attenuation values and package sizes to accommodate different circuit board space and performance requirements.

Replacement Considerations

Direct substitutes include other Venkel models in the PCAT series with similar attenuation values and package dimensions, such as the PCAT0404X-0R5BT-CT, provided the tolerance specifications meet the application requirements.
