PCAT0404X-4R0BT-CT

Overview

The PCAT0404X-4R0BT-CT is a fixed RF attenuator manufactured by Venkel. It provides an attenuation value of 4 dB with a characteristic 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 utilizes a Pi-type circuit topology and is housed in a 0404 (1010 Metric) convex surface mount package.

Feature Summary

• Pi-type chip attenuator topology for signal reduction
• Operates up to 3 GHz frequency range
• 50 Ohm characteristic impedance design
• Convex 0404 surface mount package

Applications

• RF signal path attenuation
• Impedance matching networks
• Signal level control in wireless systems

Procurement Notes

Verify the specific suffix 'CT' against the manufacturer's official documentation to confirm tape and reel packaging requirements. Ensure the 0404 convex package dimensions align with PCB footprint specifications. Confirm RoHS compliance status through the latest datasheet revision before procurement.

Selection Notes

Select this component when a precise 4 dB attenuation is required at 50 Ohms. The 100 mW power rating suits low-power RF applications. The 3 GHz bandwidth covers common communication bands. Verify thermal management needs relative to the small 0404 package size.

Part Context

This part belongs to Venkel's PCAT series of thin-film chip attenuators. These components are designed for high-frequency applications requiring stable attenuation values. The series offers various resistance values and package sizes to suit different circuit constraints.
