SF2169E

Overview

The SF2169E is a Surface Acoustic Wave (SAW) filter manufactured by RFMi, an Akoustis brand. It operates at a center frequency of 165 MHz with a bandwidth of 20 MHz and provides 9 dB insertion loss. The component is housed in an 8-SMD, No Lead package, designed for general-purpose RF signal conditioning applications requiring precise frequency selection.

Feature Summary

• Surface Acoustic Wave technology for effective RF filtering
• General-purpose design suitable for standard signal conditioning
• Compact surface-mount package for space-constrained layouts

Applications

• RF signal conditioning circuits
• Embedded systems requiring frequency filtering
• Industrial automation electronics

Procurement Notes

Verify the specific datasheet version to confirm electrical parameters, as some sources list conflicting frequencies. Confirm the manufacturer designation as RFMi or Akoustis. Check lead times, which are typically around 12 weeks. Ensure the 8-SMD no-lead package matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when a 165 MHz SAW filter is required for general RF applications. Consider the 20 MHz bandwidth and 9 dB loss specifications against system requirements. The 8-SMD package dictates board layout constraints. Verify compatibility with operating temperatures and voltage levels specified in the official documentation.
