SF2395E

Overview

The Murata Electronics SF2395E is a Surface Acoustic Wave (SAW) filter designed for general-purpose RF applications. It operates at a center frequency of 1.224 GHz with a bandwidth of 4.4 dB and an insertion loss of 4.4 dB. The component features 50 ohm and 100 ohm impedance options, housed in a compact 6-SMD, No Lead package. It supports surface mount installation and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Surface Acoustic Wave technology for RF signal filtering
• Compact 6-SMD no-lead package design
• Dual impedance configuration supporting 50 ohm and 100 ohm systems

Applications

• General purpose RF filtering
• Wireless communication modules
• RF front-end signal conditioning

Procurement Notes

Verify the current product status as the SF2395E is listed as obsolete by major distributors. Confirm availability through authorized channels or secondary markets if immediate procurement is required. Ensure that the specific impedance variant matches the circuit requirements before ordering.

Selection Notes

Select this component for designs requiring a 1.224 GHz SAW filter with low insertion loss. Consider the 6-SMD footprint constraints during PCB layout. Evaluate alternative active or passive solutions if long-term supply stability is critical due to the component's obsolete status.

Part Context

The SF2395E belongs to Murata's SAW filter portfolio, targeting mid-frequency RF applications. It complements other Murata RF components like the SF2315E and SF2395E variants, offering standardized performance for wireless infrastructure and consumer electronics requiring precise frequency selection.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should consult Murata's official cross-reference tools or engineering support for validated replacement recommendations.
