FM450K0000S114

Overview

The FM450K0000S114 is a ceramic filter manufactured by TGS, designed for surface-mount applications. It features a center frequency of 450 kHz and an impedance of 1.5 kOhm. The component utilizes a J-Lead package configuration with three pads, specifically identified as GDT style. This device is categorized under ceramic filters and is intended for signal processing tasks requiring precise frequency selection at the specified AM band.

Feature Summary

• Surface-mount construction utilizing J-Lead technology for reliable PCB attachment
• Optimized for 450 kHz center frequency operation in AM signal paths
• Integrated 1.5 kOhm impedance matching for circuit compatibility

Applications

• AM radio receiver front-end filtering
• Intermediate frequency (IF) stage signal conditioning
• Communication equipment requiring 450 kHz frequency selectivity

Procurement Notes

Verify the specific datasheet version for the FM450K0000S114 to confirm mechanical dimensions and soldering profiles. Ensure compatibility with the target PCB footprint, particularly regarding the J-Lead pad layout. Cross-reference the impedance value of 1.5 kOhm with the surrounding circuit design to prevent signal reflection or attenuation issues during integration.

Selection Notes

Select this component when a fixed 450 kHz ceramic filter is required for AM applications. The 1.5 kOhm impedance rating must match the source and load impedances of the circuit design. Consider the SMD J-Lead package for automated assembly processes. Verify that the bandwidth characteristics meet the system's selectivity requirements before finalizing the bill of materials.

Part Context

This part belongs to TGS's line of ceramic filters, which are passive components used for frequency selection. These filters are commonly employed in communication systems to isolate desired signals from noise and interference. The FM450K0000S114 specifically targets the 450 kHz range, distinguishing it from other variants in the series that may operate at different frequencies or impedances.

Replacement Considerations

Check for direct substitutes such as the FM450K0000S005 if available, ensuring identical center frequency and impedance. Verify package compatibility for any alternative components to ensure they fit the existing J-Lead footprint without redesigning the PCB.
