• Surface-mount construction for board integration
• Automotive-grade reliability certification

Applications

• Short-range communication systems
• Medical RF equipment
• Narrowband receiver front ends

Procurement Notes

Verify the manufacturer designation, as some listings attribute this part to RFMi while official datasheets identify Murata Electronics North America. Confirm the specific package variant and ensure the voltage rating aligns with system requirements. Check for AEC-Q200 compliance if automotive usage is intended. Validate the operating temperature range against environmental conditions.

Selection Notes

Select this component for applications requiring precise filtering in the 402-405 MHz spectrum. The low insertion loss supports signal integrity in sensitive receiver chains. Ensure the PCB layout accommodates the 8-terminal SMD footprint. Consider thermal management capabilities given the specified operating temperature limits.

Part Context

This SAW filter belongs to Murata's signal conditioning portfolio, designed for high-frequency applications. It serves as a critical interface component between antennas and receivers, rejecting out-of-band interference. The technology leverages surface acoustic wave propagation for compact, efficient filtering solutions in modern electronic devices.
