Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and lead-free specifications prior to procurement. Cross-reference the package dimensions with PCB footprint libraries to prevent assembly errors. Ensure the supplier provides original manufacturer documentation for quality assurance.

Selection Notes

Select this component when a 455 kHz center frequency with 24 kHz bandwidth is required for AM applications. Consider the 1 kOhm impedance match with surrounding circuitry. Evaluate the 4-SMD J-Lead package constraints against available board space. Compare insertion loss characteristics if signal attenuation is critical to system performance.

Part Context

This component belongs to TGS's FM series of ceramic filters, which are widely used in communication systems. The series offers various center frequencies and bandwidths tailored for different intermediate frequency needs. The FM455K variant specifically targets standard AM broadcast band applications, providing reliable performance in consumer audio devices.

Replacement Considerations

Check for direct substitutes such as FM455K0000S112 or similar variants within the same family. Verify that alternative parts maintain identical electrical parameters including center frequency, bandwidth, and impedance. Ensure mechanical compatibility with the existing 4-SMD J-Lead footprint before substitution.
