Procurement Notes
Verify the specific suffix Z810 against official datasheets to confirm exact electrical characteristics, as variations exist within the B39321 series. Confirm current availability status directly with authorized distributors or Qualcomm, as supply levels fluctuate. Ensure compatibility with existing PCB footprints and reflow soldering profiles specified in the manufacturer's documentation before procurement.
Selection Notes
Select this component for designs requiring a 315MHz SAW filter with specific 2.7dB bandwidth constraints. Verify that the 8-SMD package dimensions fit the mechanical layout. Consider the AEC-Q200 rating if the application demands automotive-grade reliability. Compare insertion loss performance against alternative filters in the same frequency band to ensure system efficiency requirements are met.
Part Context
This part belongs to the Qualcomm B39321 series of RF front-end filters. These components are engineered for wireless connectivity solutions, leveraging acoustic technologies to provide high-performance filtering in small form factors. The series supports various industrial and consumer applications requiring reliable signal integrity at specific RF frequencies.
Replacement Considerations
Publicly confirmed parameter-equivalent substitutes include B39321R0961H110. Verify pinout compatibility and electrical specifications before substitution.
