FL455K0000S114

Overview

The TGS FL455K0000S114 is a surface-mount ceramic filter designed for AM radio frequency applications. It features a center frequency of 455 kHz and utilizes a 3-pad SMD package with dimensions of 6.5 mm length, 6.0 mm width, and 4.2 mm height. The component specifies a maximum insertion loss of 5.0 dB and a minimum 6 dB bandwidth of ±10.0 kHz.

Feature Summary

• Surface-mount construction for automated assembly
• Optimized for AM broadcast signal processing
• Compact physical footprint

Applications

• AM radio receiver circuits
• Intermediate frequency filtering in communication devices
• RF signal conditioning modules

Procurement Notes

Verify the specific datasheet version to confirm the insertion loss specification, as sources indicate values of both 4.0 dB and 5.0 dB. Ensure the selected variant matches the required bandwidth tolerance of ±10.0 kHz or ±17.5 kHz depending on the exact sub-type intended for the design.

Selection Notes

Select this component when a 455 kHz center frequency is required for AM demodulation stages. Consider the 3-pad J-lead package compatibility with PCB layout constraints. Evaluate thermal management requirements based on the specified insertion loss limits during high-signal conditions.

Part Context

This part belongs to the FL Series of SMD ceramic filters manufactured by TGS. These components are engineered to replace traditional through-hole filters in modern electronics, offering reduced size while maintaining necessary selectivity for intermediate frequency applications in consumer audio equipment.

Replacement Considerations

The LT455EW is a comparable ceramic filter from TGS. Verify pinout compatibility and electrical specifications before substitution. Other generic 455 kHz SMD filters may require circuit re-tuning due to differences in bandwidth and impedance characteristics.
