B39431B3710U410

Overview

The B39431B3710U410 is a Surface Acoustic Wave (SAW) RF filter manufactured by Qualcomm. It operates at a center frequency of 433.92MHz with a bandwidth of 1.7MHz and insertion loss of 2dB. The component is housed in a compact 6-SMD, no-lead package measuring 3.00mm x 3.00mm x 1.10mm. Designed for remote control applications, it meets AEC-Q200 standards and complies with RoHS3 regulations. The part is currently active and available in tape and reel or cut tape packaging.

Feature Summary

• Surface Acoustic Wave technology for efficient RF signal filtering
• AEC-Q200 qualified for automotive reliability standards
• Compact surface-mount design suitable for space-constrained layouts

Applications

• Remote control systems
• Automotive RF front-end modules
• Industrial wireless communication devices

Procurement Notes

Verify the specific suffix U410 to confirm the 6-SMD package variant. Confirm RoHS3 compliance status for current production lots. Check for alternative packaging options such as Digi-Reel if low-volume prototyping is required. Ensure compatibility with existing PCB footprint dimensions of 3.00mm x 3.00mm during integration planning.

Selection Notes

Select this component when a 433.92MHz SAW filter with 1.7MHz bandwidth is required for remote control applications. The AEC-Q200 qualification makes it suitable for automotive environments. Compare against other B39431 series variants if different package sizes or bandwidths are needed. Verify that the 2dB insertion loss meets system sensitivity requirements.

Part Context

This part belongs to the Qualcomm B39431 series of RF SAW filters. The series offers various configurations for different frequencies and packages. The B39431B3710U410 specifically targets the 433.92MHz band with a smaller 6-pin footprint compared to larger 8-pin alternatives in the same family.

Replacement Considerations

The B39431B3743H110 is listed as a similar replacement option. Verify electrical parameter compatibility before substitution. Ensure the replacement matches the required package type and application specifications.
