SFELF10M7FAA0-A0

Overview

The Murata Electronics SFELF10M7FAA0-A0 is a ceramic bandpass filter designed for signal conditioning applications. It operates at a center frequency of 10.7 MHz with a bandwidth of 280 kHz. The component features a nominal impedance of 330 Ohms and utilizes a two-element internal structure to achieve the specified filtering characteristics. It is housed in a radial through-hole package suitable for board mount installation. This device belongs to the CERAFIL SF series, which is engineered for reliable performance in radio frequency signal processing tasks.

Feature Summary

• Utilizes a two-element ceramic resonator structure for precise bandpass filtering
• Designed for high selectivity at the standard 10.7 MHz intermediate frequency
• Constructed with radial leads for secure through-hole board mounting

Applications

• Intermediate frequency (IF) stages in AM/FM radio receivers
• Signal conditioning circuits requiring 10.7 MHz bandpass characteristics
• Audio demodulation systems in consumer electronics

Procurement Notes

Verify the current lifecycle status as this part may be obsolete or discontinued. Confirm that the 330 Ohm impedance matches your circuit design requirements. Ensure the radial package dimensions are compatible with your PCB footprint. Check for RoHS compliance documentation if required by your manufacturing standards. Consult official distributors for availability of replacement components if this specific model is no longer produced.

Selection Notes

Select this component when a 10.7 MHz center frequency with 280 kHz bandwidth is required. The 330 Ohm impedance rating must align with the source and load impedances of the surrounding circuitry. The radial through-hole package dictates the assembly method and PCB layout constraints. Consider the operating temperature range and physical size limitations of the target application before finalizing the selection.

Part Context

This component is part of Murata's CERAFIL SF series, a line of ceramic filters widely used in communication equipment. The SF designation typically indicates a standard bandpass filter configuration. These devices are known for their stability and compact form factor compared to older LC filter solutions. The 10.7 MHz frequency is a global standard for FM broadcast intermediate frequencies.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Verify compatibility with any alternative ceramic filters offering identical 10.7 MHz center frequency, 280 kHz bandwidth, and 330 Ohm impedance. Ensure mechanical fitment of the radial package is maintained during substitution.
