The component features an impedance of 1.5 kOhm and utilizes a 3-SMD, J-Lead package configuration. This device is part of the CFTC U series and maintains an active product status. It complies with ROHS3 standards for environmental safety. The filter provides specific frequency selection capabilities suitable for intermediate frequency stages in communication systems.

Feature Summary

• Surface-mount construction utilizing a J-Lead package for reliable PCB integration
• Fixed center frequency operation at 450 kHz with narrow 15 kHz bandwidth
• High impedance characteristic of 1.5 kOhm for signal isolation
• Compliance with ROHS3 environmental regulations

Applications

• Intermediate frequency filtering in AM radio receivers
• Signal processing circuits requiring 450 kHz frequency selection
• Communication equipment front-end stages

Procurement Notes

Verify that the ordered component matches the exact part number FL450K0000S004 to ensure correct frequency and impedance specifications. Confirm the package type is 3-SMD J-Lead as generic ceramic filters may differ in pin configuration. Check for ROHS3 compliance documentation if required by project standards. Ensure the supplier provides valid datasheets confirming the 450 kHz center frequency and 15 kHz bandwidth parameters before finalizing procurement.

Selection Notes

Select this component when a fixed 450 kHz ceramic filter is required for surface-mount assembly. The 1.5 kOhm impedance must match the circuit design requirements for proper signal transfer. Consider the 15 kHz bandwidth for application-specific selectivity needs. The J-Lead package requires compatible footprint design on the printed circuit board. Verify active status availability through authorized distributors to ensure consistent supply chain quality.

Part Context

This component belongs to the TGS ceramic filter family, specifically the CFTC U series. These filters are engineered for stable performance in intermediate frequency applications. The manufacturer specializes in passive components for electronic circuits. The FL450K0000S004 variant offers a standardized solution for 450 kHz frequency selection in consumer electronics and communication devices.

Replacement Considerations

Cross-reference with other TGS ceramic filters in the same series for potential substitutes. Verify identical center frequency, bandwidth, and impedance values before substitution. Ensure the replacement component supports the same 3-SMD J-Lead package dimensions. Confirm compatibility with existing circuit designs regarding impedance matching and frequency response characteristics.
