PCAT0404X-8R0CT-CT

Overview

The Venkel PCAT0404X-8R0CT-CT is a surface-mount RF attenuator designed for high-frequency applications. It provides a fixed attenuation value of 8dB with a tolerance of ±0.5dB. The component operates within a frequency range of 0 Hz to 3 GHz and maintains a characteristic impedance of 50 Ohms. It features a Pi-type circuit topology and is housed in a compact 0404 (1010 Metric) package. The device is rated for a maximum power handling capacity of 100mW. It is RoHS compliant and lead-free, suitable for convex mounting configurations in dense PCB layouts.

Feature Summary

• Fixed 8dB attenuation with tight tolerance for precise signal control
• Wideband operation from DC to 3 GHz ensuring consistent performance
• Compact 0404 surface-mount package for space-constrained designs
• Pi-type topology providing stable 50 Ohm impedance matching

Applications

• RF signal conditioning in wireless communication systems
• Test and measurement equipment requiring precise attenuation
• Mobile device front-end modules for signal level adjustment
• Microwave circuits needing fixed loss components

Procurement Notes

Verify the specific suffix 'CT' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure the order matches the exact part number including all alphanumeric characters to avoid receiving variants with different tolerances or power ratings. Cross-reference the RoHS compliance status with current regulatory requirements for your target market before finalizing procurement.

Selection Notes

Select this component when a fixed 8dB loss is required in a 50 Ohm system operating up to 3 GHz. The 0404 package size is ideal for applications where board real estate is limited but standard SMD footprints are insufficient. Consider the 100mW power rating to ensure it meets the thermal and power handling needs of the specific circuit path without derating issues.

Part Context

This part belongs to Venkel's PCAT series of chip attenuators, which are designed for RF and microwave applications. The series offers various attenuation values and package sizes to accommodate different design constraints. The PCAT0404X variant specifically targets high-density surface-mount technologies, providing reliable performance in consumer electronics and industrial RF systems.

Replacement Considerations

Direct substitutes must match the 8dB attenuation, 50 Ohm impedance, and 0404 package dimensions. Verify that alternative parts support the same 3 GHz frequency range and 100mW power rating. Check if the replacement uses the same Pi-type topology to ensure equivalent insertion loss and return characteristics in the circuit.
