FM455K0000S112

Overview

The FM455K0000S112 is a ceramic filter manufactured by TGS, designed for intermediate frequency (IF) applications in radio frequency circuits. It operates at a center frequency of 455 kHz and features a bandwidth of 24 kHz. The component has an impedance of 1 kOhm and is housed in a compact 4-SMD, J-Lead package. This configuration supports surface-mount assembly, facilitating integration into modern electronic designs requiring precise signal filtering.

Feature Summary

• Utilizes ceramic material for stable frequency response
• Designed for surface-mount technology integration
• Optimized for AM broadcast band intermediate frequency filtering

Applications

• AM radio receiver IF stages
• Consumer audio electronics
• Communication equipment signal processing

Procurement Notes

Verify the specific suffix 'S112' against official TGS documentation to confirm pinout and mechanical dimensions. Ensure compatibility with existing PCB footprints. Confirm that the 4-SMD J-Lead package matches the intended assembly process. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a 455 kHz center frequency with 24 kHz bandwidth is required for AM applications. Consider the 1 kOhm impedance match with preceding circuit stages. Evaluate the 4-SMD J-Lead package size for space constraints. Verify temperature stability requirements against the manufacturer's specifications.

Part Context

This component belongs to TGS's line of ceramic filters, which are widely used in consumer electronics for frequency selection. The FM series typically offers high Q-factor and sharp cutoff characteristics. These filters replace older bulky LC circuits, enabling miniaturization of radio receivers while maintaining signal integrity and selectivity.

Replacement Considerations

Check for direct substitutes like FM455K0000S002 if pin compatibility differs. Verify equivalent electrical parameters such as center frequency and bandwidth. Ensure mechanical footprint compatibility before substitution.
