Procurement Notes

Verify the specific datasheet version to confirm exact electrical tolerances and mechanical dimensions. Ensure compatibility with surface-mount assembly processes given the small footprint. Confirm RoHS3 compliance status matches regulatory requirements for the target market. Cross-reference pinout configurations if integrating into existing PCB layouts.

Selection Notes

Select this component when a fixed 455 kHz ceramic filter is required for surface-mount designs. Consider the physical dimensions of 6.50mm x 6.00mm for board space constraints. Evaluate insertion loss and attenuation characteristics against system sensitivity requirements. Verify that the grounded drain top package style aligns with thermal and mechanical design needs.

Part Context

This component belongs to the TGS ceramic filter family, specifically engineered for intermediate frequency applications. The FL series typically offers high Q-factor performance for sharp frequency selectivity. These filters are commonly used in communication devices where stable center frequency response is critical for signal integrity and noise rejection.

Replacement Considerations

Consult official substitution lists for equivalent models such as FL455K0000S113 or LT455EW. Verify that replacement parts match the 455 kHz center frequency and compatible SMD package dimensions. Ensure electrical parameters like insertion loss and bandwidth meet original design specifications before implementation.
