Procurement Notes

Verify the exact suffix H110 against the manufacturer's current ordering guide to ensure correct tape-and-reel packaging and pin configuration. Confirm that the component meets the required RoHS compliance standards for your target market. Cross-reference the datasheet revision date with your design timeline to account for any potential lifecycle changes or obsolescence notices issued by Qualcomm.

Selection Notes

Select this component when designing for LTE Band 8 coverage in compact mobile form factors. Ensure the PCB layout accommodates the specific SMD footprint dimensions provided in the mechanical drawing. Consider thermal management requirements during soldering, as SAW filters are sensitive to excessive heat exposure during reflow processes.

Part Context

This part belongs to Qualcomm's portfolio of RF filters intended for modern smartphone architectures. It supports global roaming capabilities by addressing specific European and Asian cellular bands. The component integrates into larger front-end modules or standalone filter solutions depending on the system-on-chip design strategy employed by the device manufacturer.

Replacement Considerations

Consult Qualcomm's official substitution list for direct replacements. Generic equivalents may not match the precise impedance matching or harmonic rejection profiles required for certified network operation. Verify compatibility with existing baseband processor interfaces before implementation.
