Overview
The SF2166E is a Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi. It operates at a center frequency of 1280.18 MHz with a specified bandwidth ranging from 1260.18 MHz to 1300.18 MHz. The component features a nominal impedance of 150 Ohms and a maximum insertion loss of 3.2 dB. It is rated for a voltage of 3 V and functions within an operating temperature range of -40°C to +85°C. The device utilizes an SMD/SMT termination type and is housed in an SM3030-8 package, suitable for board mount applications.
Feature Summary
- Surface Acoustic Wave technology for signal conditioning
- Bandpass filtering capability centered at 1.28 GHz
- Compact surface-mount packaging design
Applications
- TV RF signal processing
- Broadcast receiver front-ends
- Wireless communication systems requiring 1.28 GHz filtering
Procurement Notes
Verify the specific datasheet version from RFMi or authorized distributors to confirm exact electrical tolerances and RoHS compliance status. Ensure the SM3030-8 footprint matches the target PCB layout. Confirm that the 150 Ohm impedance aligns with the system interface requirements before finalizing procurement orders.
Selection Notes
Select this component when a SAW filter with a 150 Ohm impedance is required for the 1.28 GHz band. Consider the 3.2 dB insertion loss and 40 MHz bandwidth against system sensitivity needs. The -40°C to +85°C temperature range supports standard commercial and industrial environments. Verify compatibility with SMD assembly processes given the SM3030-8 package constraints.
Part Context
The SF2166E belongs to the SF series of SAW filters produced by RFMi. These components are designed for high-frequency signal conditioning tasks. The product line typically targets applications requiring precise frequency selection in the UHF and L-band ranges. RFMi manufactures these devices using established surface acoustic wave technologies.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult RFMi technical support for direct equivalents or cross-reference lists.
