SF2415E-1

Overview

The SF2415E-1 is a Surface Acoustic Wave (SAW) filter manufactured by RFMi, designed for signal conditioning in ISM band applications. It operates at a center frequency of 869 MHz with a bandwidth of 2 MHz. The component features a 50 Ohm impedance and is housed in an SM3030-6 surface-mount package. It supports supply voltages of 5V or 6V and exhibits an insertion loss of approximately 2.5 dB.

Feature Summary

• Surface Acoustic Wave technology for precise RF signal filtering
• Optimized for ISM band operations at 869 MHz
• Compact SMD/SMT packaging for automated assembly

Applications

• ISM band RF signal conditioning
• Wireless communication modules
• RF front-end filtering

Procurement Notes

Verify the specific ordering suffix to confirm voltage ratings and tolerance levels, as variations may exist between similar part numbers. Ensure compatibility with the target PCB footprint SM3030-6. Cross-reference datasheets from authorized distributors to confirm current manufacturing status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a narrow 2 MHz bandwidth is required around 869 MHz for ISM applications. Consider the 2.5 dB insertion loss impact on system sensitivity. Verify that the 50 Ohm impedance matches the surrounding circuit design. Confirm the SM3030-6 package dimensions fit the mechanical constraints of the enclosure.

Part Context

This SAW filter belongs to RFMi's lineup of passive RF components tailored for industrial, scientific, and medical frequency bands. It serves as a critical element for noise reduction and signal integrity in wireless transceivers operating within the global ISM spectrum allocations.

Replacement Considerations

Direct substitutes require matching 869 MHz center frequency, 2 MHz bandwidth, and SM3030-6 package. Verify insertion loss and impedance specifications against the original design requirements to ensure functional equivalence.
