• Optimized for Satellite Digital Audio Radio Service (SDARS)
• AEC-Q200 automotive qualification

Applications

• SDARS receiver front-end filtering

Procurement Notes

Verify current availability status as the SF2038B may be discontinued or subject to limited supply constraints. Confirm exact packaging quantities and lead times directly with authorized distributors or Murata Electronics representatives prior to procurement planning. Ensure compatibility with existing design specifications before finalizing orders.

Selection Notes

Select this component for designs requiring precise 76.5MHz SAW filtering in SDARS systems. Consider the 10-SMD footprint and 2.00mm height for PCB layout constraints. Verify thermal operating ranges and impedance matching requirements against system specifications to ensure optimal signal integrity and performance stability.

Part Context

The SF2038B belongs to Murata's SF series of SAW filters, specifically engineered for automotive audio applications. It serves as a critical intermediate frequency or radio frequency filter in satellite radio receivers, providing necessary selectivity and noise rejection within compact surface-mount packages suitable for modern electronic assemblies.

Replacement Considerations

The SF2038B-2 is a documented variant within the same product family. Verify electrical parameter equivalence and pinout compatibility before substitution. Consult official Murata documentation for detailed cross-reference information and functional differences between these specific part numbers.
