PCAT0404X-6R0CT

Overview

The PCAT0404X-6R0CT is a surface-mount Pi-type chip attenuator manufactured by Venkel. It provides a fixed attenuation of 6 dB with an impedance of 50 Ohms. The device operates within a frequency range of 0 Hz to 3 GHz and has a power rating of 100 mW. It is housed in a 0404 (1010 Metric) convex package. The component is RoHS compliant and lead-free, designed for high-reliability RF applications requiring precise signal reduction.

Feature Summary

• Pi-type architecture for stable attenuation performance
• Convex package design suitable for surface mount assembly
• RoHS compliant construction ensuring environmental safety

Applications

• RF signal conditioning circuits
• Impedance matching networks
• Signal level adjustment in communication systems

Procurement Notes

Verify the specific ordering suffix CT against official Venkel documentation to confirm tape and reel packaging requirements. Ensure the requested part number matches the exact attenuation value and package type specified in the design schematic. Cross-reference the manufacturer series designation to avoid confusion with similar product lines.

Selection Notes

Select this component when a fixed 6 dB attenuation is required at 50 Ohms within the 3 GHz bandwidth. Consider the 100 mW power handling capability relative to the application's signal levels. The 0404 footprint must align with the PCB land pattern. Verify that the convex package profile fits within the mechanical constraints of the enclosure.

Part Context

This part belongs to Venkel's PCAT series of passive chip attenuators. These components are engineered for consistent performance in RF environments. The series offers various attenuation values and impedance options, all utilizing robust surface-mount technology. The PCAT0404X variant specifically denotes the 0404 package size and convex form factor.

Replacement Considerations

Direct substitutes include other Venkel PCAT series parts with identical 6 dB attenuation, 50 Ohm impedance, and 0404 convex package dimensions. Verify that alternative manufacturers' equivalents match the 100 mW power rating and 3 GHz frequency limit to ensure functional parity.
