SF2344D-241-10

Overview

The SF2344D-241-10 is a Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi. It operates at a center frequency of 241 MHz with a bandwidth of 5 MHz, covering a range from 240.9 MHz to 241.1 MHz. The component features an insertion loss of 2.2 dB and supports impedances of 50 Ohms and 200 Ohms. It is rated for a voltage of 3 V and functions within a temperature range of -10°C to +85°C. The device utilizes SMD/SMT termination in an SM3838-8 package and holds AEC-Q200 qualification.

Feature Summary

• Surface Acoustic Wave technology for precise signal conditioning
• AEC-Q200 qualified for automotive reliability standards
• Compact surface-mount design for board integration

Applications

• Automotive radio receiver front-end filtering
• Signal conditioning in 241 MHz communication systems
• RF module intermediate frequency stages

Procurement Notes

Verify the specific suffix against official RFMi documentation to confirm impedance and packaging variations. Ensure compatibility with AEC-Q200 requirements if used in automotive contexts. Confirm RoHS3 compliance status through current datasheets before procurement.

Selection Notes

Select this component when a narrow 5 MHz bandwidth is required at 241 MHz. Consider the 50/200 Ohm impedance options for circuit matching. Verify thermal limits align with the -10°C to +85°C operating range for the target environment.

Part Context

This part belongs to the RFMi SF series of SAW filters. It is designed for high-selectivity applications requiring stable performance in compact form factors. The SM3838-8 package allows for automated surface-mount assembly processes.

Replacement Considerations

Check for direct substitutes such as SF2344D variants with different suffixes. Verify electrical equivalence for center frequency and bandwidth before substitution.
