PCAT0404X-100CT-CT

Overview

The Venkel PCAT0404X-100CT-CT is a surface-mount RF attenuator designed for high-frequency applications. It provides a nominal attenuation of 10dB with an impedance of 50 Ohms. The device operates within a frequency range of 0 Hz to 3 GHz and has a power handling capability of 100mW. It utilizes a Pi-type circuit topology and is housed in a convex 0404 (1010 Metric) package, ensuring reliable performance in compact electronic designs.

Feature Summary

• Pi-type chip attenuator architecture
• Convex 0404 surface mount package
• 50 Ohm impedance matching

Applications

• RF signal conditioning
• Impedance matching networks
• Signal level adjustment in microwave circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact electrical tolerances and package variations. Ensure that the component meets all required RoHS compliance standards for your assembly process. Cross-reference the part number with authorized distributors to confirm availability and authenticity before placing orders.

Selection Notes

Select this component when a precise 10dB attenuation is required at 50 Ohms within the 3 GHz bandwidth. Consider the 100mW power rating and the physical dimensions of the 0404 convex package during PCB layout. Evaluate thermal management requirements relative to the specified power dissipation limits for the intended operating environment.

Part Context

This component belongs to Venkel's PCAT series of surface-mount RF attenuators. The series offers various attenuation values and impedance options in standardized packages. The PCAT0404X variant specifically denotes the 0404 footprint size with a convex profile, distinguishing it from flat or other package styles within the broader product line.

Replacement Considerations

Consult official cross-reference data for compatible substitutes. Verify that any alternative part matches the 10dB attenuation, 50 Ohm impedance, and 0404 package dimensions to ensure mechanical and electrical compatibility without redesigning the host circuit.
