DC455K0000S139

Overview

The TGS DC455K0000S139 is a ceramic filter component manufactured by TGS. It functions as a center discriminator with a specified center frequency of 455 kHz and a bandwidth of 3 kHz. The device utilizes a surface-mount technology (SMD) package configuration, specifically designed for integration into electronic circuits requiring precise frequency discrimination at the intermediate frequency range.

Feature Summary

• Provides center discriminator functionality for signal processing applications
• Utilizes ceramic material construction for stable frequency characteristics
• Designed for surface-mount assembly to facilitate automated PCB placement

Applications

• Intermediate frequency filtering in communication receivers
• Frequency discrimination in analog demodulation circuits
• Signal processing stages in broadcast equipment

Procurement Notes

Verify the exact physical dimensions and pinout configuration against the official datasheet before finalizing the PCB footprint design. Confirm that the 455 kHz center frequency and 3 kHz bandwidth specifications align precisely with the system requirements. Ensure compatibility with the intended surface-mount assembly process and reflow soldering profiles to maintain component integrity during manufacturing.

Selection Notes

Select this component when a dedicated ceramic center discriminator is required for 455 kHz applications. Consider the SMD form factor for space-constrained designs. Evaluate the 3 kHz bandwidth against the necessary signal selectivity and distortion requirements of the specific circuit topology to ensure optimal performance without excessive insertion loss or phase distortion.

Part Context

This part belongs to the TGS ceramic filters family, which specializes in passive components for frequency selection. The DC series typically denotes center discriminator variants within this lineup. These components are engineered to replace bulkier mechanical filters, offering improved reliability and consistency in mass-produced electronic devices operating at standard intermediate frequencies.
