DC455K0000S124

Overview

The DC455K0000S124 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 features a two-pad SMD package and exhibits an insertion loss of 3 dB. Physical dimensions are specified as L6.2 x W6.0 x H3.1 mm, housed in a white case. It supports a maximum reflow profile temperature of 260 °C.

Feature Summary

• Surface-mount ceramic construction for compact integration
• Discriminator function optimized for 455 kHz applications
• Low-cost design suitable for high-volume production

Applications

• AM radio receiver intermediate frequency stages
• Consumer electronics requiring 455 kHz filtering
• Industrial control systems using ceramic discriminators

Procurement Notes

Verify the specific datasheet revision (e.g., A0 dated May 04, 2021) to ensure compatibility with current manufacturing standards. Confirm that the 260 °C reflow limit aligns with your assembly process capabilities. Ensure the 455 kHz center frequency matches your circuit design requirements precisely before procurement.

Selection Notes

Select this component when a low-profile, cost-effective ceramic discriminator is required for 455 kHz signals. The 4 kHz bandwidth defines its selectivity characteristics. Consider the 3 dB insertion loss impact on signal strength within your system architecture. The SMD form factor dictates PCB layout constraints regarding pad spacing and thermal management during soldering.

Part Context

This part belongs to the TGS ceramic filter family, specifically designed as a discriminator type. It is distinct from standard bandpass filters due to its specific phase response characteristics tailored for demodulation applications. The 6260 type designation refers to its physical footprint and pin configuration standard within the manufacturer's catalog.

Replacement Considerations

Check for direct substitutes such as the DC455K0000S103 if available, ensuring identical electrical parameters and mechanical dimensions. Verify that any replacement maintains the 455 kHz center frequency and 4 kHz bandwidth specifications to prevent performance degradation in the target application.
