Overview
The TGS FL455K0000S004 is a surface-mount ceramic filter from the CFTC U series, designed for intermediate frequency applications. It operates at a center frequency of 455.0 kHz with a specified bandwidth of 5 kHz and an impedance of 1.5 kOhm. The component features a 3-pad SMD J-lead package with dimensions of 6.5 mm length, 6.0 mm width, and 4.2 mm height. Key electrical specifications include a maximum insertion loss of 5.0 dB and a minimum 6 dB bandwidth of +/-7.5 kHz.
Feature Summary
- Surface-mount construction utilizing a 3-pad J-lead configuration for automated assembly compatibility.
Applications
- Intermediate frequency stages in AM radio receivers
Procurement Notes
Verify the specific suffix 'S004' against the manufacturer's current datasheet to confirm pinout orientation and terminal plating specifications. Ensure the selected variant matches the required 1.5 kOhm impedance and 455 kHz center frequency for the target circuit design. Cross-reference the package dimensions (6.5x6.0x4.2mm) with PCB footprint requirements prior to procurement.
Selection Notes
Select this component when a 455 kHz center frequency with 1.5 kOhm impedance is required for AM signal processing. The surface-mount J-lead package facilitates high-volume manufacturing integration. Confirm that the 5.0 dB maximum insertion loss meets the system sensitivity requirements. Verify that the physical dimensions fit within the designated board space constraints.
Part Context
This part belongs to the TGS CFTC U series of KHz SMD ceramic filters. The series utilizes a standardized 6560 type housing format. The designation indicates a fixed-frequency device optimized for narrowband filtering applications in consumer electronics and communication equipment.
