FM450K0000S009

Overview

The FM450K0000S009 is a ceramic filter manufactured by TGS, designed for AM radio frequency applications. It features a center frequency of 450 kHz and utilizes a 4-SMD, J-Lead package with dimensions of 12.0mm length, 6.5mm width, and 3.0mm height. The component has a nominal impedance of 1.5 kOhm and a maximum insertion loss of 7.0 dB. Its bandwidth specification indicates a 6dB bandwidth of +/- 2.0 kHz minimum.

Feature Summary

• Utilizes a 4-SMD J-Lead surface mount package for compact integration
• Engineered for AM signal processing at 450 kHz center frequency
• Provides defined impedance matching with 1.5 kOhm nominal resistance

Applications

• AM radio receiver intermediate frequency stages
• Audio signal filtering in communication devices
• Embedded systems requiring specific RF bandpass characteristics

Procurement Notes

Verify the exact part number suffix against official TGS documentation to ensure correct bandwidth and package specifications. Confirm RoHS compliance status through manufacturer datasheets or authorized distributor declarations before procurement. Ensure compatibility with existing PCB footprint designs regarding the 4-SMD J-Lead configuration.

Selection Notes

Select this component when a 450 kHz center frequency with narrow bandwidth is required for AM applications. Consider the 1.5 kOhm impedance requirement for circuit matching. Evaluate the physical dimensions of the 4-SMD J-Lead package against available board space constraints.

Part Context

This component belongs to the CFTC W Series of ceramic filters from TGS. These filters are typically used in analog signal processing circuits where stable frequency selection is critical. The series offers various bandwidth options tailored for different radio standards.

Replacement Considerations

Cross-reference with FL450K0000S114 if a wider 15 kHz bandwidth is acceptable. Verify electrical parameters such as insertion loss and impedance match before substituting.
