B39431B3727H110

Overview

The B39431B3727H110 is a Surface Acoustic Wave (SAW) filter manufactured by Qualcomm, designed for remote control applications. It operates at a center frequency of 433.92MHz with a bandwidth of 1.7MHz and an insertion loss of 2.8dB. The component features a compact 6-SMD, no-lead package measuring 3.00mm x 3.00mm x 1.00mm. It holds AEC-Q200 qualification and complies with RoHS3 standards.

Feature Summary

• AEC-Q200 qualified for automotive reliability
• Compact 3.00mm x 3.00mm surface mount footprint
• Optimized for remote control RF signal integrity

Applications

• Remote control systems
• Automotive keyless entry
• Industrial remote monitoring

Procurement Notes

Verify the specific suffix H110 to confirm the 6-pin SMD configuration and 1.7MHz bandwidth. Confirm AEC-Q200 status if automotive compliance is required. Check current availability as distribution may vary. Ensure compatibility with existing PCB land patterns for 6-SMD packages.

Selection Notes

Select this part for designs requiring a small form factor SAW filter in the 433MHz band. The 6-terminal layout differs from common 8-terminal variants. Consider the 2.8dB insertion loss impact on system sensitivity. Verify thermal management requirements for surface mount operation.

Part Context

Part of the B39431 series of RF front-end filters. Designed to replace older 8-pin or 4-pin SAW components in space-constrained remote control circuits. Provides standardized performance for ISM band applications.
