Procurement Notes

Verify the specific manufacturer designation, as the component is associated with both RFMi and Akoustis. Confirm the exact datasheet version matches the required electrical specifications, particularly regarding insertion loss and temperature ratings. Ensure the SM3838-8 package dimensions align with the target PCB layout before finalizing procurement decisions.

Selection Notes

Select this component when a 500 MHz center frequency with 24 MHz bandwidth is required for RF signal paths. The choice is driven by the need for SAW-based filtering in compact SMD packages. Consider the operating temperature range and insertion loss characteristics relative to system requirements. Verify compatibility with standard reflow soldering profiles specified in the official documentation.

Part Context

The SF2433D belongs to the SF series of bandpass filters produced by RFMi, an Akoustis brand. These components are part of a broader portfolio of RF solutions utilizing SAW, crystal, and ceramic technologies. The series targets digital and wireless communication markets, providing signal conditioning for various frequency bands including WiFi and LTE applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing should be performed using identical electrical parameters such as 500 MHz center frequency, 24 MHz bandwidth, and 50 Ohm impedance.
