Procurement Notes

Verify the specific suffix code on the datasheet or official ordering guide to confirm exact electrical tolerances and packaging options. Ensure compatibility with your PCB footprint and reflow soldering profile. Confirm that the operating temperature range meets your system requirements. Always refer to the latest manufacturer documentation for pinout and mechanical drawings before integration.

Selection Notes

Select this component when harmonic suppression is critical in broadband RF paths between 470 and 698 MHz. Consider its physical size if board real estate is limited. Evaluate insertion loss impact on overall system gain. Verify power handling limits against maximum expected signal levels to prevent damage. Compare alternative filters based on required stopband depth and bandwidth specifications.
