DC455K0000S166

Overview

The TGS DC455K0000S166 is a ceramic center discriminator filter designed for intermediate frequency applications. It operates at a center frequency of 455 kHz with a demodulated bandwidth of ±4.2 kHz at the 3dB points. The component utilizes a surface-mount device (SMD) package configuration, specifically featuring two pads for circuit integration. Its physical dimensions are approximately 6.2 mm in length, 6.0 mm in width, and 3.1 mm in height. This series belongs to the DCBC product line, indicating its classification within TGS's specialized ceramic filter portfolio for signal processing.

Feature Summary

• Integrated center discriminator functionality for direct demodulation applications
• Surface-mount construction optimized for automated PCB assembly processes
• Fixed 455 kHz center frequency specification for standard IF stages

Applications

• Intermediate frequency filtering in AM radio receivers
• Demodulation circuits in analog communication systems
• Signal processing stages requiring fixed-frequency ceramic discrimination

Procurement Notes

Verify the specific datasheet version from TGS or authorized distributors to confirm mechanical tolerances and electrical characteristics. Ensure compatibility with reflow soldering profiles suitable for ceramic components. Confirm that the 2-pad SMD footprint matches the target PCB design layout. Check for RoHS compliance status if required by environmental regulations.

Selection Notes

Select this component when a fixed 455 kHz center frequency with ±4.2 kHz bandwidth is required for demodulation. Consider the SMD package size constraints during PCB layout. Evaluate thermal management requirements as ceramic filters have specific operating temperature ranges. Compare against alternative ceramic discriminators if different bandwidths or frequencies are needed.

Part Context

This part belongs to the TGS DCBC series of ceramic filters, which are widely used in consumer electronics for audio and RF signal processing. The DC455K0000S166 specifically targets the common 455 kHz intermediate frequency standard used in broadcast reception. It serves as a critical passive component for maintaining signal integrity and enabling demodulation in analog receiver architectures.

Replacement Considerations

Cross-reference with other TGS models in the DC series for similar specifications. Verify pinout and dimensional compatibility before substituting with generic equivalents. Ensure replacement parts meet the same 455 kHz center frequency and bandwidth requirements.
