SF2352H

Overview

The SF2352H is a Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi, an Akoustis brand. Designed for signal conditioning applications, this component operates at a center frequency of 403.5 MHz with a bandwidth ranging from 402 MHz to 405 MHz. It features a typical insertion loss of 2.5 dB and maintains a system impedance of 200 Ohms. The device is housed in a compact SM2016-4 surface-mount package, measuring approximately 2.0 mm by 1.6 mm. It is rated under the AEC-Q200 standard, indicating suitability for automotive-grade reliability requirements.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise signal filtering
• Optimized for high-reliability automotive environments via AEC-Q200 rating
• Compact surface-mount design facilitates automated assembly

Applications

• Automotive telematics systems
• Vehicle-to-everything (V2X) communication modules
• General-purpose RF signal conditioning circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the AEC-Q200 qualification status aligns with your project's automotive reliability standards. Cross-reference the SM2016-4 footprint dimensions with your PCB layout guidelines to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when a 200-Ohm impedance interface is required for the RF front-end. The 403.5 MHz center frequency targets specific regional or specialized wireless bands distinct from common cellular frequencies. Ensure the application can accommodate the specified 2.5 dB insertion loss within the overall link budget calculations before finalizing the design.

Part Context

RFMi is a division of Akoustis Technologies specializing in radio frequency components. The SF2352H belongs to the SAW filter product line, which leverages acoustic wave propagation for frequency selection. This series supports various industrial and automotive connectivity solutions, providing stable performance across temperature variations while maintaining small form factors suitable for modern electronic devices.

Replacement Considerations

No public substitute part numbers are confirmed for this specific model. Direct replacement requires matching the 403.5 MHz center frequency, 200 Ohm impedance, and SM2016-4 package dimensions exactly.
