FM455K0000S003

Overview

The FM455K0000S003 is a ceramic filter manufactured by TGS, designed for AM radio applications. It features a center frequency of 455 kHz and a bandwidth of 20 kHz. The component exhibits an insertion loss of 4 dB and an impedance of 1.5 kOhm. It is housed in a 4-SMD, J-Lead package with dimensions of 12.00mm x 7.50mm.

Feature Summary

• Designed specifically for AM radio signal filtering applications
• Utilizes ceramic technology for stable frequency response
• Surface-mount construction for automated assembly

Applications

• AM radio receiver circuits
• Intermediate frequency (IF) filtering in broadcast receivers
• Audio signal processing stages requiring 455 kHz selectivity

Procurement Notes

Verify the specific suffix S003 against official TGS documentation to confirm pinout and tolerance specifications. Ensure compatibility with 4-SMD J-Lead footprints during PCB layout. Confirm RoHS3 compliance status through current manufacturer declarations rather than distributor summaries.

Selection Notes

Select this component when a 455 kHz center frequency with 20 kHz bandwidth is required for AM reception. Consider the 1.5 kOhm impedance match with preceding amplifier stages. Evaluate the 4 dB insertion loss impact on overall receiver sensitivity compared to alternative ceramic filters.

Part Context

This part belongs to the TGS ceramic filter family, which provides passive components for radio frequency and intermediate frequency applications. These filters are commonly used in consumer electronics to isolate desired signals from adjacent channel interference in analog broadcasting systems.

Replacement Considerations

LT455EW is a documented substitute ceramic filter from TGS. Verify electrical parameters such as bandwidth and impedance before substitution.
