DC455K0000S127

Overview

The DC455K0000S127 is a surface-mount ceramic discriminator filter manufactured by TGS. It operates at a center frequency of 455 kHz with a bandwidth of 4 kHz. The component utilizes a 2-pad SMD package, featuring a white case with dimensions of 6.2 mm in length, 6.0 mm in width, and 3.1 mm in height. This device is designed for applications requiring precise frequency discrimination within the AM radio intermediate frequency range.

Feature Summary

• Integrated ceramic discriminator structure for FM/AM signal processing
• Compact surface-mount design suitable for automated assembly
• White casing for visual identification and standard footprint compatibility

Applications

• AM/FM radio receiver intermediate frequency stages
• Consumer audio equipment signal processing
• Industrial communication devices requiring 455 kHz filtering

Procurement Notes

Verify the specific suffix 'S127' against the manufacturer's current datasheet to ensure correct pinout and tolerance specifications. Confirm RoHS3 compliance status if environmental regulations apply to your manufacturing process. Check for alternative packaging options such as tape and reel versus bulk, as availability may vary by distributor. Ensure the receiving facility supports the specified 2-pad SMD footprint during PCB layout validation.

Selection Notes

Select this component when a dedicated ceramic discriminator is required rather than a standard bandpass filter. The 4 kHz bandwidth is critical for maintaining audio fidelity in AM reception while rejecting adjacent channel interference. Consider the physical dimensions of 6.2x6.0x3.1 mm for space-constrained board layouts. Verify that the operating temperature range meets the environmental conditions of the final application.

Part Context

This part belongs to TGS's series of ceramic filters and discriminators, specifically designed for intermediate frequency applications. The DCBC series designation indicates its classification within the manufacturer's product line. These components are widely used in legacy and modern consumer electronics where reliable frequency selection is necessary without the complexity of active circuits.

Replacement Considerations

Cross-reference with part number DC455K0000S128 from NextGen Components documentation for potential equivalent specifications. Verify mechanical compatibility and electrical performance before substitution. Ensure the replacement maintains the 455 kHz center frequency and 4 kHz bandwidth requirements.
