SF2367B

Overview

The RFMi SF2367B is a narrow-band Surface Acoustic Wave (SAW) filter designed for signal conditioning applications. It operates at a center frequency of 169.4375 MHz with a specified bandwidth of 80 kHz, covering a range from 169.407 MHz to 169.467 MHz. The component supports a maximum voltage rating of 3 V and features a steep transition to the stopband for effective interference rejection. It is housed in a hermetic 5 x 7 mm surface-mount case, ensuring durability and consistent performance in demanding RF environments.

Feature Summary

• Narrow-band SAW technology providing precise frequency selection
• Steep transition characteristics to enhance stopband rejection
• Hermetic surface-mount packaging for environmental protection

Applications

• RF signal conditioning in transmitters
• Frequency control elements in wireless communication systems
• Narrow-band filtering in industrial telemetry

Procurement Notes

Verify the specific ordering suffix against official RFMi documentation to confirm exact electrical tolerances and package variations. Ensure compatibility with existing PCB footprints for the 5x7 mm case size. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a fixed center frequency of approximately 169.4 MHz is required with tight bandwidth constraints. The 3 V rating limits its use to low-power signal paths. Consider the hermetic package if operating in harsh environments where moisture or contamination resistance is critical for long-term reliability.

Part Context

This device belongs to the RFMi family of SAW filters and resonators, which are engineered as frequency control elements for digital and wireless applications. RFMi, an Akoustis brand, specializes in SAW, crystal, and ceramic technologies. This specific model targets narrow-band requirements within their broader portfolio of timing and frequency products.

Replacement Considerations

No public substitute part numbers are confirmed in available documentation. Verify pinout and electrical specifications carefully before considering any alternative SAW filters from other manufacturers.
