PCAT0404X-5R0BT-CT

Overview

The PCAT0404X-5R0BT-CT is a Pi-type chip attenuator manufactured by Venkel. It provides a nominal attenuation of 5dB with a characteristic impedance of 50 Ohms. The device operates within a frequency range of 0 Hz to 3 GHz and supports a power rating of 100mW. It utilizes a convex package configuration in the 0404 (1010 Metric) footprint, designed for surface mount applications requiring precise RF signal control.

Feature Summary

• Pi-type attenuator topology for stable impedance matching
• Convex package design suitable for high-frequency operations
• Operates across a broad frequency spectrum up to 3 GHz

Applications

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

Procurement Notes

Verify RoHS compliance status and specific package dimensions against the official datasheet before integration. Confirm that the 100mW power rating aligns with your circuit's thermal requirements. Ensure the 50 Ohm impedance matches your system design to prevent signal reflections. Check for any specific handling instructions regarding the convex package structure during assembly.

Selection Notes

Select this component when a 5dB attenuation value is required at 50 Ohms. The 0404 footprint offers a compact solution for space-constrained designs. Consider the 3 GHz frequency limit for your application bandwidth. The convex package may influence soldering profiles compared to standard flat packages.
