DC455K0000S128

Overview

The DC455K0000S128 is a center discriminator ceramic filter manufactured by TGS. It operates at a center frequency of 455 kHz with a bandwidth of 4 kHz. The component utilizes a 2-SMD surface-mount package design, suitable for integration into compact electronic circuits requiring precise frequency discrimination.

Feature Summary

• Center discriminator functionality for frequency selection
• Ceramic construction for stable performance
• Surface-mount device (SMD) form factor

Applications

• AM radio receiver intermediate frequency stages
• Frequency discrimination circuits
• Communication equipment signal processing

Procurement Notes

Verify the manufacturer designation as TGS and confirm the part number DC455K0000S128 matches the required 455 kHz center frequency and 4 kHz bandwidth specifications. Ensure the 2-SMD package type aligns with the printed circuit board layout requirements before procurement.

Selection Notes

Select this component when a specific 455 kHz center discriminator response is required in a surface-mount application. Consider the 4 kHz bandwidth constraint to ensure compatibility with the desired signal modulation characteristics and adjacent channel rejection needs within the target circuit design.

Part Context

This component belongs to the category of ceramic filters produced by TGS. It serves as a passive frequency-selective element, distinct from active components or other filter technologies like SAW or LC filters, providing a dedicated solution for fixed-frequency discrimination tasks in consumer electronics.

Replacement Considerations

Cross-reference with equivalent 455 kHz center discriminator ceramic filters from other manufacturers. Verify that any substitute maintains identical center frequency, bandwidth, and 2-SMD package dimensions to ensure mechanical and electrical compatibility without redesigning the host circuit.
