WA04PR05XATL

Overview

The WA04PR05XATL is a surface-mount RF attenuator manufactured by Walsin Technology Corporation. It provides a nominal attenuation of 0.5 dB with a tolerance of ±0.1 dB. The component operates at a characteristic impedance of 50 Ohms and supports frequencies up to 3 GHz. It features a power rating of 100 mW and a maximum operating voltage of 50 V. The device utilizes silicon technology and is housed in an SMD/SMT package, specifically the 0404 (1010 Metric) footprint. It functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides precise signal reduction for radio frequency circuits
• Designed for high-frequency operation up to 3 GHz
• Utilizes silicon-based construction for stability

Applications

• RF signal conditioning in wireless communication systems
• Impedance matching networks in microwave circuits
• Signal level adjustment in test and measurement equipment

Procurement Notes

Verify the specific suffix 'ATL' against the manufacturer's official datasheet to confirm the exact packaging configuration and tape specifications. Ensure that the 0404 footprint dimensions align with the target PCB layout constraints. Confirm RoHS compliance status through the latest environmental documentation provided by Walsin Technology Corporation prior to finalizing procurement orders.

Selection Notes

Select this component when a minimal attenuation value of 0.5 dB is required for 50 Ohm systems. The wide operating temperature range makes it suitable for industrial applications. Consider the low power rating of 100 mW when designing circuits with higher signal levels to prevent thermal damage. The small 0404 package is ideal for space-constrained designs.

Part Context

This part belongs to the WA04P series of RF attenuators from Walsin Technology Corporation. The series offers various attenuation values tailored for different RF circuit requirements. The WA04PR05XATL specifically addresses the need for fine-tuning signal strength in high-frequency applications where standard discrete components may not provide sufficient precision or consistency.
