• Designed for general purpose RF applications
• Compact SM3030 surface-mount package

Applications

• Wireless communication systems
• RF signal filtering
• General purpose RF circuits

Procurement Notes

Verify the specific datasheet version when sourcing, as specifications may vary slightly between revisions. Confirm RoHS compliance status directly with the supplier or manufacturer documentation before integration. Ensure the SM3030 footprint matches your PCB layout requirements. Check that the operating temperature range meets your environmental conditions. Validate the 6V rating against your circuit's voltage levels.

Selection Notes

Select this component when a narrow 7 MHz bandwidth is required around 866.5 MHz. The 50 Ohm impedance ensures compatibility with standard RF transmission lines. Consider the SM3030 package size for space-constrained designs. The wide operating temperature range suits industrial or automotive environments. Verify insertion loss tolerance for system sensitivity requirements.

Part Context

This part belongs to the SF2413 series of SAW filters from RFMi. These components are engineered for precise frequency selection in RF front-ends. The series typically offers consistent performance across similar center frequencies. RFMi specializes in passive RF components for wireless infrastructure.

Replacement Considerations

Check for direct substitutes with identical 866.5 MHz center frequency and 7 MHz bandwidth. Ensure replacement parts match the SM3030 package dimensions and pin configuration. Verify that alternative SAW filters maintain the same 50 Ohm impedance and insertion loss characteristics.
