B39431R800H210W3

Overview

The B39431R800H210W3 is a Surface Acoustic Wave (SAW) filter manufactured by Qualcomm Technologies, designed for remote control applications. It operates at a center frequency of 433.92 MHz and features an insertion loss of 1.2 dB. The component utilizes a Tape & Reel (TR) package with dimensions of 0.197 inches in length by 0.138 inches in width (5.00 mm x 3.50 mm). It has a Moisture Sensitivity Level (MSL) rating of 1, indicating unlimited exposure to ambient conditions.

Feature Summary

• Utilizes Surface Acoustic Wave (SAW) technology for RF filtering
• Optimized for low insertion loss performance
• Designed for surface mount installation

Applications

• Remote control systems
• General purpose RF applications

Procurement Notes

Verify the specific datasheet version for the B39431R800H210W3, as documentation references may vary. Confirm that the 1.2 dB insertion loss specification aligns with your design requirements. Ensure compatibility with the 433.92 MHz operating frequency. Check for any Product Change Notifications (PCN) regarding manufacturing origin or assembly changes. Validate package dimensions against PCB footprint constraints.

Selection Notes

Select this component when a compact SAW filter is required for 433.92 MHz remote control signals. The 1.2 dB insertion loss offers efficient signal transmission. The small 5.00 mm x 3.50 mm footprint suits space-constrained designs. Ensure the application does not require higher power handling than standard SAW filters provide.
