PCAT0404X-1R0BT

Overview

The Venkel PCAT0404X-1R0BT is a surface-mount RF attenuator designed for high-frequency applications. It provides a fixed attenuation value of 1 dB with a tolerance of ±0.5 dB. The component operates within a frequency range of 0 Hz to 3 GHz and maintains a characteristic impedance of 50 Ohms. It features a convex package style in the 0404 (1010 Metric) footprint, suitable for automated assembly. The device is rated for a maximum power dissipation of 100 mW, ensuring reliable performance in signal conditioning circuits.

Feature Summary

• Fixed 1 dB attenuation for precise signal level control
• Broadband operation up to 3 GHz frequency range
• Convex 0404 surface-mount package design
• 50 Ohm impedance matching for RF systems

Applications

• RF signal path attenuation
• Impedance matching networks
• Test and measurement equipment
• Wireless communication modules

Procurement Notes

Verify the specific suffix 'CT' indicates tape and reel packaging when ordering. Confirm the 100 mW power rating aligns with system thermal requirements. Ensure the 0404 convex footprint matches PCB land pattern specifications. Check RoHS compliance status for environmental regulations. Validate the 3 GHz upper frequency limit against application bandwidth needs.

Selection Notes

Select this component when a precise 1 dB reduction is required in 50 Ohm RF environments. Consider the 0404 size constraint for board space limitations. Evaluate the 100 mW power handling capability against peak signal levels. Compare the 3 GHz bandwidth against higher frequency alternatives if needed. Assess the convex package profile for solder joint reliability.

Part Context

This part belongs to Venkel's PCAT series of thin-film chip attenuators. The series offers various attenuation values in compact surface-mount packages. The 0404 form factor allows for dense circuit board layouts. Venkel specializes in passive components for demanding electronic applications.

Replacement Considerations

Direct substitutes include other Venkel models with identical 1 dB attenuation and 0404 convex packaging, such as PCAT0404X-1R0BT-CT. Cross-brand replacements require matching 50 Ohm impedance, 3 GHz frequency range, and 100 mW power rating. Verify footprint compatibility before substitution.
