PCAT0404X-3R0BT-CT

Overview

The PCAT0404X-3R0BT-CT is a Pi-type chip attenuator manufactured by Venkel. It provides an attenuation value of 3dB within a frequency range of 0 Hz to 3 GHz. The component features a characteristic impedance of 50 Ohms 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 circuit topology for balanced signal attenuation
• Convex package profile optimized for surface mounting
• Designed for high-frequency operation up to 3 GHz
• Maintains 50 Ohm system impedance compatibility

Applications

• RF signal level adjustment in communication systems
• Impedance matching networks in microwave circuits
• Test and measurement equipment signal conditioning
• Wireless infrastructure component integration

Procurement Notes

Verify the specific suffix 'CT' against the manufacturer's current datasheet to confirm tape and reel packaging specifications. Ensure the 100mW power rating aligns with your thermal management requirements. Confirm RoHS compliance status directly with Venkel documentation prior to final procurement approval.

Selection Notes

Select this component when a fixed 3dB attenuation is required in a compact 0404 footprint. The 50 Ohm impedance makes it suitable for standard RF transmission lines. Consider the 3 GHz upper frequency limit to ensure performance stability at your operating frequency. The convex shape may influence solder paste volume selection during assembly.

Part Context

This part belongs to Venkel's PCAT series of thin-film chip attenuators. These components are engineered for precision RF applications where stable attenuation values are critical. The series offers various attenuation levels and package sizes to accommodate different PCB layout constraints and power handling needs in modern electronic designs.

Replacement Considerations

Consult Venkel's official substitution guide for equivalent parts. Verify that any alternative maintains the same 3dB attenuation, 50 Ohm impedance, and 0404 package dimensions. Ensure frequency response characteristics match the original specification to prevent signal integrity issues.
