PCAT0404X-7R0CT

Overview

The PCAT0404X-7R0CT is a surface-mount RF attenuator manufactured by Venkel. It features a Pi-type topology and provides a nominal attenuation of 7 dB. The device operates within a frequency range of 0 Hz to 3 GHz with a characteristic impedance of 50 Ohms. It has a maximum power handling capacity of 100 mW. The component utilizes a convex package design in the 0404 (1010 Metric) footprint, suitable for high-frequency circuit applications requiring precise signal level control.

Feature Summary

• Pi-type chip attenuator topology
• Convex package design for thermal stability
• 50 Ohm characteristic impedance
• Operates up to 3 GHz frequency range

Applications

• RF signal conditioning circuits
• Test and measurement equipment
• Wireless communication systems

Procurement Notes

Verify the specific ordering suffix matches the required tolerance and termination specifications. Confirm the package orientation and pin configuration align with the PCB layout. Ensure the supplier provides valid RoHS compliance documentation. Check that the component is sourced from authorized Venkel distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when a 7 dB fixed attenuation is required in 50 Ohm systems. Consider the 100 mW power rating against expected signal levels. Evaluate the 0404 footprint constraints against available board space. Verify frequency performance requirements do not exceed the 3 GHz upper limit.

Part Context

This part belongs to Venkel's PCAT series of surface-mount attenuators. The series offers various attenuation values in standardized packages. The 0404 size balances component density with power handling capabilities. It is designed for integration into compact RF modules and high-density electronic assemblies.

Replacement Considerations

Direct substitutes must match the 7 dB attenuation, 50 Ohm impedance, and 0404 footprint. Verify equivalent power ratings and frequency ranges. Consult manufacturer cross-reference lists for compatible alternatives with identical electrical characteristics.
