PCAT0404X-8R0CT

Overview

The PCAT0404X-8R0CT is a Pi-type chip attenuator manufactured by Venkel. It provides an attenuation value of 8dB within a frequency range of 0 Hz to 3 GHz. The component features a 50 Ohm impedance and a power rating of 100mW. It utilizes a 0404 (1010 Metric) convex package design, suitable for surface mount applications in RF circuits requiring precise signal reduction.

Feature Summary

• Pi-type architecture for stable attenuation performance
• Convex package profile facilitating reliable surface mounting
• Designed for high-frequency operation up to 3 GHz

Applications

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

Procurement Notes

Verify the specific suffix 'CT' against the manufacturer's official datasheet to confirm tape-and-reel packaging details. Ensure the 100mW power rating aligns with your circuit's thermal requirements. Confirm that the 0404 footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when an 8dB fixed attenuation is required at 50 Ohms. The 0404 size offers a compact solution for space-constrained designs. Consider the 100mW power limit to ensure safe operation within your system's voltage and current parameters without exceeding thermal specifications.

Part Context

This part belongs to Venkel's PCAT series of passive chip attenuators. These components are engineered for precision RF applications where consistent impedance matching and low reflection are critical. The series supports various attenuation values across standard impedance levels.

Replacement Considerations

Consult Venkel's official substitution guide for equivalent parts. Verify that any alternative maintains the 8dB attenuation, 50 Ohm impedance, and 0404 package dimensions to ensure mechanical and electrical compatibility.
