DC455K0000S149

Overview

The DC455K0000S149 is a ceramic filter manufactured by TGS, designed as a 455kHz center discriminator. It operates with a center frequency of 455 kHz and features a bandwidth of 4 kHz. The component utilizes a 2-SMD surface-mount package configuration. This device belongs to the DC series of ceramic filters and is intended for applications requiring precise intermediate frequency filtering and discrimination in electronic circuits.

Feature Summary

• Functions as a ceramic discriminator filter centered at 455 kHz
• Utilizes a compact 2-SMD surface-mount package design
• Provides a defined 4 kHz bandwidth for signal selection

Applications

• Intermediate frequency stages in radio receivers
• Discriminator circuits in FM demodulation systems
• Signal processing in communication equipment

Procurement Notes

Verify the specific suffix S149 against the manufacturer's current specification sheet R1008-DC455K0000S149 to ensure compatibility with required tolerance and pinout configurations. Confirm that the 2-SMD footprint matches the target PCB layout. Cross-reference the center frequency and bandwidth parameters with system requirements to ensure proper signal discrimination performance.

Selection Notes

Select this component when a fixed 455 kHz ceramic discriminator is required for AM or FM intermediate frequency applications. Ensure the circuit design accommodates the 4 kHz bandwidth characteristic. Verify that the surface-mount package size fits within the available board space constraints. Consider thermal management and soldering profiles suitable for ceramic components during assembly.

Part Context

This part is part of TGS's DC series of ceramic filters. These components are widely used in consumer electronics and industrial communication devices where stable frequency discrimination is necessary. The 455 kHz standard is common in legacy and specialized radio frequency applications.

Replacement Considerations

Check for direct substitutes from TGS such as LT455GW or other DC series variants. Verify that any replacement maintains the 455 kHz center frequency and compatible 4 kHz bandwidth. Ensure physical package dimensions and electrical characteristics match the original design requirements.
