B39321B3781Z810

Overview

The B39321B3781Z810 is a Surface Acoustic Wave (SAW) filter designed for remote control applications. It operates at a center frequency of 315MHz with a bandwidth of 550kHz and an insertion loss of 1.8dB. The component is housed in an 8-SMD, no-lead package measuring 3.80mm x 3.80mm x 1.50mm. It meets AEC-Q200 standards and complies with RoHS3 regulations.

Feature Summary

• Utilizes Surface Acoustic Wave technology for RF filtering
• Optimized for low insertion loss performance
• Designed for compact surface mount integration
• Complies with automotive reliability standards

Applications

• Remote control systems
• RF front-end signal processing

Procurement Notes

Verify the specific part number suffix to ensure correct packaging configuration, as variants such as tape-and-reel or cut-tape may exist. Confirm that the 315MHz specification matches the target application requirements. Check for RoHS3 compliance documentation if environmental regulations apply. Ensure the 8-SMD footprint aligns with the PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a 315MHz SAW filter is required for remote control circuits. The 550kHz bandwidth provides necessary selectivity for this frequency band. The 1.8dB insertion loss offers efficient signal transmission. The small 3.80mm x 3.80mm package suits space-constrained designs. Verify compatibility with existing RF front-end architectures.

Part Context

This component belongs to Qualcomm's RF front-end filter portfolio, which includes various SAW and BAW technologies. These filters are engineered for wireless connectivity solutions across mobile, IoT, and infrastructure sectors. The B39321 series specifically targets remote control and industrial applications requiring reliable acoustic filtering.

Replacement Considerations

The B39321B3761Z810 is a similar 315MHz SAW filter but features a narrower 360kHz bandwidth and 1.9dB insertion loss. Substitution requires verification of bandwidth and loss specifications against circuit requirements.
