SF2412E

Overview

The Murata Electronics SF2412E is a Surface Acoustic Wave (SAW) bandpass filter designed for RF signal conditioning. It operates at a center frequency of 925 MHz with a bandwidth of 6 MHz and an insertion loss of 2.9 dB. The component utilizes a compact 6-SMD, no-lead package measuring 3.00 mm x 3.00 mm with a maximum height of 1.40 mm. It supports a voltage rating of 3 V and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Surface mount SAW technology for precise RF filtering
• Compact 3.00 mm x 3.00 mm footprint suitable for space-constrained designs
• Low insertion loss characteristics for efficient signal transmission

Applications

• Meter reading systems
• RF signal conditioning circuits
• Industrial instrumentation

Procurement Notes

Verify current availability status as the SF2412E has been marked as obsolete or end-of-life by the manufacturer. Confirm RoHS compliance details and check for valid replacement components from Murata's current portfolio before finalizing procurement plans.

Selection Notes

Select this component only if the specific 925 MHz center frequency and 6 MHz bandwidth align with system requirements. Ensure the design accommodates the 6-SMD package dimensions and thermal operating limits. Consider alternative active or passive filters if SAW technology constraints are unsuitable.

Part Context

This part belongs to Murata's SAW filter family, specifically engineered for narrowband applications. It serves as a critical interface component in radio frequency front-ends, providing frequency selectivity and noise rejection for dedicated communication protocols.

Replacement Considerations

Check Murata's official obsolescence notices for recommended cross-reference parts. Verify electrical compatibility including center frequency, bandwidth, and insertion loss when selecting substitutes.
