Overview
The TGS FL450K0000S113 is a ceramic filter designed for AM radio applications, operating at a center frequency of 450 kHz. It features a bandwidth of 20 kHz and an impedance of 1.5 kOhm. The component utilizes a 3-SMD, J-Lead package with dimensions of 6.50mm x 6.00mm. Maximum insertion loss is specified at 5.0 dB, while the 6dB bandwidth is +/-10.0 kHz minimum.
Feature Summary
- Designed specifically for AM signal processing applications
- Utilizes a compact surface-mount J-Lead package configuration
- Provides stable center frequency operation at 450 kHz
Applications
- AM radio receiver intermediate frequency stages
- Signal filtering in broadcast audio equipment
- Intermediate frequency selection in communication circuits
Procurement Notes
Verify the specific suffix code to ensure correct impedance and bandwidth specifications, as variations exist within the series. Confirm package compatibility with PCB footprint requirements before ordering. Cross-reference official datasheets for precise electrical tolerances and thermal handling limits to ensure reliable integration into final designs.
Selection Notes
Select this component when a 450 kHz center frequency with 1.5 kOhm impedance is required for AM applications. Ensure the design accommodates the 3-SMD J-Lead form factor. Compare insertion loss and bandwidth specifications against system requirements to verify signal integrity needs are met without excessive attenuation or insufficient selectivity.
Part Context
This part belongs to the TGS CFTC U series of ceramic filters. These components are engineered for cost-effective signal filtering in consumer electronics. The series offers various impedance and bandwidth options tailored for different radio frequency standards, providing a standardized solution for intermediate frequency processing in analog receivers.
Replacement Considerations
FL450K0000S112 is a similar variant but operates at 1kOhm impedance rather than 1.5kOhm. Verify circuit matching requirements before substitution. Other parts in the FL450K series may share the same frequency but differ in physical dimensions or electrical characteristics.
