SF2039B-2

Overview

The Murata SF2039B-2 is a Surface Acoustic Wave (SAW) filter designed for intermediate frequency applications. It operates at a center frequency of 72.54 MHz and is housed in a 10-SMD, no-lead package with dimensions of 5.0 x 7.0 mm. The component supports both differential and single-ended input configurations, offering low insertion loss characteristics suitable for signal conditioning tasks.

Feature Summary

• Designed specifically for SDARS IF receiver applications
• Supports differential or single-ended input configurations
• Utilizes surface acoustic wave technology for signal filtering

Applications

• SDARS IF Receiver
• Signal Conditioning
• Intermediate Frequency Filtering

Procurement Notes

Verify the current manufacturing status as sources indicate this product may be discontinued. Confirm package compatibility with the 10-SMD no-lead form factor. Ensure the 72.54 MHz specification matches system requirements. Check RoHS compliance documentation before integration.

Selection Notes

Select this component for applications requiring precise 72.54 MHz SAW filtering. Consider the 5.0 x 7.0 mm footprint for board layout constraints. Evaluate the low insertion loss benefit for sensitive receiver chains. Verify support for differential signaling if required by the design architecture.

Part Context

This part belongs to Murata's SAW filter portfolio, often categorized under signal conditioning components. It shares design principles with other SDARS-focused filters but is distinct due to its specific 72.54 MHz center frequency and 10-pin SMD packaging configuration.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. Consult Murata official documentation for end-of-life alternatives or cross-reference with compatible 72.54 MHz SAW filters from the same manufacturer family.
