DC455K0000S179

Overview

The DC455K0000S179 is a ceramic filter manufactured by TGS, designed as a 455 kHz center discriminator. It features a 2-pad surface-mount device (SMD) package configuration. The component operates with a specified bandwidth of 3 kHz at its center frequency. This passive electronic component belongs to the ceramic filters category and is intended for signal processing applications requiring precise frequency discrimination.

Feature Summary

• Functioning as a 455 kHz center discriminator
• Utilizes a 2-pad SMD package format
• Constructed from ceramic materials for stability

Applications

• FM radio receiver intermediate frequency stages
• Signal processing circuits requiring 455 kHz discrimination
• Consumer electronics audio demodulation

Procurement Notes

Verify the manufacturer part number DC455K0000S179 against official TGS documentation to ensure authenticity. Confirm that the received component matches the 2-pad SMD physical dimensions and 455 kHz specification. Request the original datasheet PDF for detailed electrical characteristics and handling instructions prior to final acceptance.

Selection Notes

Select this component when a 455 kHz ceramic discriminator is required in a surface-mount design. Ensure the circuit layout accommodates the 2-pad footprint. Verify that the 3 kHz bandwidth aligns with the system's intermediate frequency requirements. Consider thermal and mechanical constraints associated with SMD ceramic packages during PCB design.

Part Context

This component is part of TGS's ceramic filter portfolio, specifically tailored for FM broadcast band applications. It serves as a passive frequency-selective element within receiver architectures. The designation indicates its role in discriminating signals around the standard 455 kHz intermediate frequency point used in analog communication systems.

Replacement Considerations

Consult official TGS substitution lists for compatible alternatives. Cross-reference pinout compatibility and electrical specifications such as center frequency and bandwidth before integrating substitute parts. Generic equivalents may not match the specific discriminator characteristics of the DC455K0000S179.
