FL450K0000S110

Overview

The TGS FL450K0000S110 is a ceramic filter designed for AM radio applications. It operates at a center frequency of 450 kHz with a bandwidth of 35 kHz and an impedance of 1 kOhm. The component utilizes a 3-SMD, J-Lead package configuration. This device is part of the CFTC U series and maintains an active product status within the manufacturer's catalog.

Feature Summary

• Designed specifically for AM signal filtering applications
• Utilizes a compact surface-mount J-Lead package structure
• Provides stable impedance matching for intermediate frequency stages

Applications

• AM radio receiver intermediate frequency circuits
• Consumer audio equipment signal processing
• Broadcast reception systems requiring 450 kHz filtering

Procurement Notes

Verify the specific suffix code to ensure correct bandwidth selection, as variants like S111 and S112 offer different bandwidths. Confirm the package type matches the PCB footprint requirements. Check current product status to ensure availability for long-term production needs. Validate datasheet revisions for any parameter updates before final design integration.

Selection Notes

Select this component when a 35 kHz bandwidth is required for AM reception at 450 kHz. Ensure the circuit design supports the 1 kOhm impedance specification. Compare against other series members if tighter or wider bandwidths are needed. Verify thermal and mechanical constraints for the chosen surface-mount mounting method.

Part Context

This component belongs to the TGS ceramic filter family, which offers various center frequencies and bandwidths for radio applications. The FL450K series targets standard AM broadcast bands. Other models in the lineup provide alternative bandwidths such as 30 kHz or 24 kHz for different selectivity requirements.

Replacement Considerations

Direct substitutes include FL450K0000S111 (30 kHz bandwidth) and FL450K0000S112 (24 kHz bandwidth). These share the same center frequency and package but differ in bandwidth specifications. Ensure the application tolerates the altered selectivity characteristics before substitution.
