SF2314E

Overview

The Murata SF2314E is a Surface Acoustic Wave (SAW) filter designed for cellular RF applications, specifically operating at a center frequency of 866 MHz. It features a bandwidth of 7 MHz and an insertion loss of 2.3 dB. The component utilizes a 6-SMD, no-lead package with dimensions of 3.00mm x 3.00mm x 1.38mm. It operates with a 50 Ohm impedance and supports a voltage rating of 3 V. The device is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1.

Feature Summary

• Utilizes Surface Acoustic Wave technology for efficient signal filtering in RF circuits
• Optimized for low insertion loss to maintain signal integrity in cellular communication systems
• Compact surface-mount design suitable for space-constrained mobile device layouts

Applications

• Cellular RF front-end modules
• Mobile phone transceivers
• Wireless communication devices requiring 866 MHz band filtering

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package marking matches the 6-SMD no-lead specification. Check datasheet revisions for any parameter updates prior to integration. Ensure storage conditions comply with MSL 1 requirements to prevent moisture damage during assembly.

Selection Notes

Select this component when designing for the 866 MHz cellular band with strict size constraints. Consider the 2.3 dB insertion loss impact on system gain budget. Evaluate thermal performance within the 3.00mm x 3.00mm footprint. Verify compatibility with existing PCB layout guidelines for 6-SMD packages.

Part Context

Part of the Murata SF23 series SAW filters, engineered for high-frequency RF applications. Designed to replace older discrete filter solutions with integrated surface-mount alternatives. Supports modern mobile device miniaturization trends while maintaining signal purity in crowded spectrum environments.

Replacement Considerations

This part is officially listed as End-of-Life (EOL). No direct public substitute part numbers are confirmed in available documentation. Designers must evaluate alternative SAW filters from Murata or other manufacturers with matching 866 MHz center frequency and 7 MHz bandwidth specifications.
