DC455K0000S140

Overview

The DC455K0000S140 is a ceramic filter manufactured by TGS, specifically designed as a center discriminator. It operates at a center frequency of 455 kHz with a bandwidth of 4 kHz. The component utilizes a 2-SMD surface-mount package. Physical dimensions are specified as 0.244 inches in length and 0.236 inches in width, with a maximum height of 0.122 inches.

Feature Summary

• Integrated center discriminator functionality for signal processing
• Surface mount construction for automated assembly

Applications

• FM radio receiver circuits
• Intermediate frequency filtering in communication devices
• Audio demodulation stages

Procurement Notes

Verify the specific suffix 'S140' against the manufacturer's current datasheet to confirm pinout and tolerance specifications. Ensure compatibility with existing PCB footprint dimensions of 6.20mm x 6.00mm. Cross-reference with equivalent part numbers such as LT455EW if sourcing alternatives, noting that package variations may exist within the same family.

Selection Notes

Select this component when a 455 kHz center frequency discriminator is required for FM detection applications. The 4 kHz bandwidth suits standard broadcast audio requirements. Verify that the 2-SMD package aligns with the design's surface-mount capabilities and thermal constraints. Confirm insertion loss characteristics meet system sensitivity targets.

Part Context

This part belongs to TGS's line of ceramic filters, which includes various frequencies and packages. Similar models like the LT455EW share the 455 kHz operating range but may differ in physical dimensions or electrical tolerances. The S140 suffix typically denotes specific mechanical or electrical variants within the manufacturer's catalog.

Replacement Considerations

LT455EW is a documented alternative from TGS offering similar 455 kHz discriminator functionality. Verify dimensional compatibility before substitution, as package sizes may vary between specific model suffixes.
