DC450K0000S049

Overview

The TGS DC450K0000S049 is a ceramic filter designed for AM radio frequency applications. It operates at a center frequency of 450 kHz with a bandwidth of 4 kHz. The component utilizes a 2-SMD surface-mount package and features an impedance of 1 kOhm. This active part serves as a center discriminator within communication circuits, providing signal filtering capabilities for specific broadcast bands.

Feature Summary

• Provides center discrimination functionality for AM radio signals
• Utilizes ceramic construction for stable RF performance
• Designed for surface-mount integration in compact electronic assemblies

Applications

• AM radio receiver front-end filtering
• Communication equipment signal processing
• RF circuit intermediate frequency stages

Procurement Notes

Verify the exact electrical parameters against the manufacturer's datasheet before procurement. Confirm that the 2-SMD package dimensions match your PCB footprint requirements. Ensure compatibility with your assembly process specifications. Cross-reference the part number to avoid confusion with similar variants like FL450K0000S114 which may have different bandwidth characteristics.

Selection Notes

Select this component when a 450 kHz center frequency with narrow 4 kHz bandwidth is required for AM discrimination. Consider the 1 kOhm impedance matching needs of your circuit design. Evaluate the surface-mount form factor against available board space constraints compared to through-hole alternatives.

Part Context

This component belongs to the TGS ceramic filter family, specifically optimized for AM broadcast band applications. It complements other filters in the series such as the FL450K0000S114, differing primarily in bandwidth and specific functional designation as a center discriminator rather than a general passband filter.

Replacement Considerations

Check for direct substitutes from TGS or compatible manufacturers offering identical 450 kHz center frequency and 4 kHz bandwidth. Verify pinout compatibility for the 2-SMD package. Ensure impedance levels remain consistent to maintain circuit performance without redesign.
