SF2378E

Overview

The SF2378E is a general-purpose Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi. It operates at a center frequency of 925.2 MHz with a bandwidth of 5.8 MHz. The device supports a voltage rating of 3 V and features an insertion loss of 2.5 dB. It is housed in a compact 6-SMD, No Lead package with dimensions of 3.0 x 3.0 mm. The component functions within a frequency range of 922.3 MHz to 928.1 MHz and maintains a 50 Ohm impedance.

Feature Summary

• Utilizes Surface Acoustic Wave technology for high performance in a small form factor
• Designed as a general-purpose RF bandpass filter
• RoHS compliant construction

Applications

• Wireless communication systems
• Digital signal conditioning
• RF front-end filtering

Procurement Notes

Verify the specific datasheet version from authorized distributors such as Mouser Electronics or DigiKey Marketplace to confirm current RoHS compliance status and exact pinout configurations. Ensure the selected component matches the required 3V rating and 50-ohm impedance specifications for your circuit design before finalizing procurement orders.

Selection Notes

Select this component when a compact SAW filter is required for applications near 925 MHz. The 3.0 x 3.0 mm package size suits space-constrained designs. Confirm that the 5.8 MHz bandwidth aligns with the system's spectral requirements and that the 2.5 dB insertion loss meets the link budget constraints.

Part Context

RFMi, now part of Akoustis, specializes in RF components using SAW, crystal, and ceramic technologies. The SF2378E belongs to their SAW filter lineup, which emphasizes small size and high performance for digital and wireless applications. This model is distinct from other series like the SF2368E or SF2388E due to its specific frequency and bandwidth parameters.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative SAW filters only through direct electrical parameter comparison and official manufacturer cross-reference lists.
