SF2472E

Overview

The SF2472E is a Surface Acoustic Wave (SAW) filter manufactured by RFMi, designed for signal conditioning applications. It operates at a center frequency of 869 MHz with a bandwidth of 2 MHz, covering the range from 868 MHz to 870 MHz. The component features an insertion loss of 1.9 dB and is rated for a voltage of 3 V. It is housed in an SM-3030-8 package, measuring 3.00mm x 3.00mm, utilizing SMD/SMT termination. The device meets AEC-Q200 qualification standards and functions within a temperature range of -45°C to +125°C.

Feature Summary

• AEC-Q200 qualified for automotive reliability requirements
• Surface Acoustic Wave technology for precise frequency filtering
• Compact SM-3030-8 surface mount package design

Applications

• Automotive telematics systems
• General purpose RF signal conditioning
• Wireless communication modules requiring 868-870 MHz filtering

Procurement Notes

Verify the specific manufacturer designation, as sources indicate both RFMi and Akoustis branding for this part number. Confirm the package type is indeed 8-SMD No Lead and validate the insertion loss specification against the latest official datasheet, as discrepancies exist between 1.9 dB and 24 dB in available records. Ensure the AEC-Q200 rating is current for the specific production batch.

Selection Notes

Select this component when a narrow band SAW filter is required for the 868-870 MHz ISM band. The AEC-Q200 certification makes it suitable for automotive environments. Consider the 3V rating and low insertion loss for sensitive RF front-end designs. The compact 3x3mm footprint aids in space-constrained PCB layouts.

Part Context

This part belongs to the SF series of SAW filters from RFMi. It is categorized under signal conditioning components. The device is currently listed as active. It serves as a specialized filter for radio frequency applications, distinct from general-purpose discrete components.

Replacement Considerations

No publicly confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires verification of electrical parameters and package dimensions with potential alternatives.
