SFELA10M7DF0021-B0

Overview

The Murata Electronics SFELA10M7DF0021-B0 is a ceramic filter designed for signal conditioning applications. It operates at a center frequency of 10.7 MHz with a bandwidth of 200 kHz, suitable for FM reception circuits. The component features an impedance of 470 Ohms and utilizes a 3-SIP package with a 2.50 mm pitch. This leaded filter is manufactured under the CERAFIL series and is RoHS compliant.

Feature Summary

• Provides precise frequency selection for FM intermediate frequency stages
• Utilizes robust ceramic resonator technology for stable performance
• Designed for surface or through-hole board mounting configurations

Applications

• FM radio receiver intermediate frequency filtering
• Signal conditioning in communication equipment
• Audio processing circuits requiring 10.7 MHz selectivity

Procurement Notes

Verify the specific suffix B0 against official Murata documentation to confirm pinout and mechanical dimensions. Ensure compatibility with existing PCB footprints given the 2.50 mm pitch specification. Cross-reference the 470 Ohm impedance requirement with circuit design parameters to maintain signal integrity. Confirm RoHS compliance status if required by regional regulations.

Selection Notes

Select this component when a 10.7 MHz center frequency with 200 kHz bandwidth is required for FM applications. The 470 Ohm impedance matches standard IF transformer designs. Consider the 3-SIP package size for space-constrained layouts. Verify operating temperature ranges against environmental conditions before integration into the final assembly.

Part Context

This part belongs to the Murata CERAFIL series of ceramic filters. These components are widely used in consumer electronics for audio and RF signal processing. The SFEL prefix indicates a specific family of leaded ceramic filters optimized for cost-effective mass production in standard electronic assemblies.

Replacement Considerations

Check for direct substitutes within the SFEL series that share identical electrical parameters. Verify mechanical footprint compatibility if replacing on existing boards. Consult Murata's obsolescence notices for alternative recommendations if this specific suffix is discontinued.
