Overview
The DC455K0000S129 is a ceramic center discriminator filter manufactured by TGS, designed for intermediate frequency (IF) applications. It operates at a center frequency of 455 kHz with a specified bandwidth of 4 kHz. The component utilizes a 2-SMD surface-mount package, measuring approximately 6.20mm in length and 6.00mm in width. It features an impedance of 1kOhm and an insertion loss of 3dB. This device is engineered to provide precise frequency discrimination within compact electronic circuits.
Feature Summary
- Integrated center discriminator functionality for FM demodulation
- Surface-mount design for automated assembly compatibility
- Fixed 455 kHz center frequency operation
Applications
- FM radio receiver IF stages
- Consumer audio equipment signal processing
- Industrial communication modules requiring 455 kHz discrimination
Procurement Notes
Verify the original manufacturer designation, such as TGS Crystals or CDBC, against the specific part code DC455K0000S129. Confirm RoHS compliance status and ensure the supplier provides genuine factory-sealed units with recent date codes. Cross-reference technical specifications like impedance and bandwidth to avoid substitution errors with similar models.
Selection Notes
Select this component when a dedicated ceramic discriminator is required rather than a standard bandpass filter. Ensure the circuit design accommodates the 1kOhm impedance and 3dB insertion loss characteristics. Verify that the 2-SMD footprint dimensions align with the PCB layout constraints for reliable soldering and mechanical stability.
Part Context
This part belongs to the TGS ceramic filter family, specifically the CFTC series or similar discriminator lines. It serves as a specialized passive component for frequency selection and demodulation in analog radio systems. The model number indicates its specific electrical parameters and physical configuration within the manufacturer's catalog.
Replacement Considerations
Publicly confirmed substitute part numbers include DC455K0000S128 and DC455K0000S150. Verify that alternative models match the 455 kHz center frequency and compatible impedance before implementation.
