Procurement Notes

Verify the specific suffix designation against official Walsin documentation to ensure correct tolerance and packaging specifications. Confirm RoHS compliance status and lead-free characteristics prior to integration. Cross-reference the datasheet for exact thermal and electrical limits to prevent operational failure in high-density designs.

Selection Notes

Select this component when a fixed 10 dB reduction is required in 50 Ohm systems operating below 3 GHz. Ensure the 100 mW power handling capacity aligns with the system's signal strength. The 0404 footprint must be compatible with the target PCB layout constraints and assembly processes.

Part Context

This part belongs to the WA04P series of ceramic chip attenuators from Walsin Technology Corporation. The series offers various attenuation values tailored for RF applications. These components are designed to replace discrete resistor networks, providing consistent performance in space-constrained electronic assemblies.

Replacement Considerations

Direct substitutes include other WA04P series variants with different attenuation values if the dB requirement changes. Verify pin compatibility and thermal characteristics when considering alternative manufacturers' equivalent 0404 RF attenuators.
