Overview
The SF2089C is a general-purpose Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi. It operates at a center frequency of 327.5 MHz with a bandwidth of 35 MHz, covering a range from 310 MHz to 345 MHz. The component exhibits an insertion loss of 12 dB and is housed in an 8-SMD, no-lead surface-mount package. The maximum height of the device is 1.70 mm (0.067 inches). This filter is designed for signal conditioning applications requiring precise frequency selection within the specified RF range.
Feature Summary
- Utilizes Surface Acoustic Wave technology for efficient signal filtering
- Provides defined bandpass characteristics centered at 327.5 MHz
- Designed for surface-mount integration into compact electronic assemblies
Applications
- Wireless communication equipment signal conditioning
- OEM devices requiring internet connectivity and control
- General purpose RF signal filtering in consumer electronics
Procurement Notes
Verify the specific datasheet version provided by RFMi or authorized distributors to confirm exact electrical tolerances and mechanical dimensions. Ensure compatibility with surface-mount assembly processes given the 8-SMD no-lead package configuration. Cross-reference the part number SF2089C against official RFMi documentation to validate performance specifications prior to integration.
Selection Notes
Select this component when a SAW filter with a 327.5 MHz center frequency and 35 MHz bandwidth is required. Consider the 12 dB insertion loss and 1.70 mm profile for space-constrained designs. Confirm that the 8-SMD package aligns with the target PCB layout and manufacturing capabilities for surface-mount technology.
Part Context
RFMi, now part of Akoustis Technologies, specializes in RF components utilizing SAW, crystal, and ceramic technologies.
