PCAT0404X-100CT

Overview

The PCAT0404X-100CT is a Pi-type chip attenuator manufactured by Venkel. It provides an attenuation value of 10dB with a frequency range spanning from 0 Hz to 3 GHz. The component operates at a characteristic impedance of 50 Ohms and has a maximum power handling capability of 100mW. It utilizes a convex package configuration in the 0404 (1010 Metric) footprint, designed for surface-mount applications.

Feature Summary

• Pi-type circuit topology for signal attenuation
• Convex package profile for surface mounting
• Designed for 50 Ohm RF systems

Applications

• RF signal level adjustment
• Impedance matching networks
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'CT' against the manufacturer's current ordering guide to ensure correct packaging and tape-and-reel specifications. Confirm that the 100mW power rating aligns with your system's thermal requirements. Check for any lead-free or RoHS compliance documentation if required by your manufacturing standards. Ensure the 0404 footprint matches your PCB design constraints.

Selection Notes

Select this component when a fixed 10dB attenuation is required within the 0-3 GHz bandwidth. The 50 Ohm impedance is standard for most RF interfaces. Consider the 100mW power limit for signal strength. The convex 0404 package offers a compact solution for space-constrained designs. Compare with other values in the PCAT0404X series if different attenuation levels are needed.

Part Context

This part belongs to Venkel's PCAT0404X series of Pi-type chip attenuators. The series offers various attenuation values while maintaining consistent 50 Ohm impedance and 0404 package dimensions. These components are engineered for high-frequency performance and reliability in RF circuits.

Replacement Considerations

Other values in the PCAT0404X series may serve as alternatives if different attenuation is acceptable. Verify that any substitute maintains the 50 Ohm impedance and 0404 convex footprint. Cross-reference with other manufacturers' 0404 Pi attenuators only if electrical parameters match exactly.
