PCAT0404X-2R0BT-CT

Overview

The PCAT0404X-2R0BT-CT is a Pi-type chip attenuator manufactured by Venkel. It operates within a frequency range of 0 Hz to 3 GHz and features a nominal impedance of 50 Ohms. The device provides an attenuation value of 2 dB with a tolerance of ±0.10 dB, indicated by the 'B' suffix. Rated for 100 mW power handling, it utilizes a 0404 (1010 Metric) convex package. This surface-mount component is designed for high-frequency signal management applications requiring precise attenuation characteristics.

Feature Summary

• Pi-type circuit topology for balanced signal attenuation
• Convex package design suitable for standard SMT processes
• Optimized for operation up to 3 GHz frequency range

Applications

• RF signal path conditioning
• Test and measurement equipment calibration
• Wireless communication system integration

Procurement Notes

Verify the specific model designation against official Venkel documentation to ensure accuracy. Confirm that the required attenuation value and power rating align with the target circuit specifications. Check for any specific handling requirements related to the convex package geometry during assembly. Ensure compliance with relevant industry standards for RF components used in the intended application environment.

Selection Notes

Select this component when a fixed 2 dB attenuation is required in a 50 Ohm system operating below 3 GHz. Consider the 100 mW power limit to prevent thermal degradation. Evaluate the 0404 footprint constraints against available PCB space. Compare performance metrics against alternative attenuator types if broader frequency ranges or different topologies are necessary for the design.

Part Context

This part belongs to Venkel's PCAT series of precision chip attenuators. These components are engineered for consistent performance in RF environments. The series offers various attenuation values and package sizes to support diverse design needs. Venkel focuses on high-reliability passive components for demanding electronic applications.

Replacement Considerations

Consult official Venkel substitution guides for verified alternatives. Cross-reference technical parameters such as attenuation tolerance, frequency response, and power rating before considering other manufacturers' products. Ensure physical footprint compatibility if replacing within an existing layout.
