B39871B3903U510

Overview

The B39871B3903U510 is a Surface Acoustic Wave (SAW) filter manufactured by Qualcomm, designed for remote control applications. It operates at a center frequency of 869MHz with a bandwidth of 2MHz and insertion loss of 1.4dB. The component utilizes a 6-SMD, no-lead package measuring 3.00mm x 3.00mm in size and 1.00mm in maximum height. It complies with RoHS3 standards and has a Moisture Sensitivity Level (MSL) of 1.

Feature Summary

Utilizes surface acoustic wave technology for RF filtering
Designed specifically for remote control applications
Compact surface mount packaging for space-constrained designs

Applications

Remote control systems
RF front-end modules

Procurement Notes

Verify the specific datasheet version and manufacturing origin, as Qualcomm RFFE filters may be produced under license or acquired entities. Confirm that the 6-SMD package dimensions and electrical parameters match the design requirements exactly. Ensure compliance with current environmental regulations such as RoHS3 and REACH status before finalizing procurement decisions.

Selection Notes

Select this component when a narrow 2MHz bandwidth SAW filter is required for 869MHz remote control signals. The 6-SMD footprint offers a compact solution compared to larger packages. Consider the 1.4dB insertion loss impact on system sensitivity. Verify availability as supply chain statuses for specific suffixes can vary.

Part Context

This part belongs to the B39871 series of RF front-end filters from Qualcomm. The series includes various SAW and BAW technologies tailored for mobile, IoT, and infrastructure applications. This specific model targets the remote control segment, differing from cellular duplexers in the same family by its lower frequency and narrower bandwidth specifications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official Qualcomm resources for potential obsolescence notices or recommended replacements if this specific suffix becomes unavailable.
