Procurement Notes

Verify the specific ordering suffix, such as TR for tape and reel packaging, when placing orders. Confirm that the supplier provides official datasheets from RFMi or Akoustis to ensure component authenticity. Check terminal configurations and mounting requirements against your PCB design specifications before procurement.

Selection Notes

Select this component when a 175 MHz SAW filter is required for RF signal conditioning. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range. Verify that the 50 Ohm impedance matches your system design and that the 10-terminal SMD package fits your layout constraints.

Part Context

RFMi, now part of Akoustis, specializes in RF components using SAW, crystal, and ceramic technologies. The SF series includes various SAW filters for different frequency bands.
