TCK-103

Overview

The TCK-103 is a through-hole common mode choke manufactured by Traco Power. It features an inductance of 285 µH ±35% per winding, measured at 100 kHz and 100 mV. The component has a maximum DC resistance (DCR) of 6 mΩ and supports a rated current of up to 16 A. Designed for PCB mounting, it serves as an EMC filter for power lines.

Feature Summary

• Provides common mode noise suppression for differential signal or power lines
• Utilizes wirewound core technology for high current handling capability
• Designed for through-hole PCB integration

Applications

• EMC filtering for DC/DC converters
• Power line noise suppression in industrial equipment
• Common mode interference reduction in electronic assemblies

Procurement Notes

Verify the specific datasheet version when ordering, as impedance and inductance tolerances are critical for EMC compliance. Confirm that the 16 A rated current aligns with the application's peak load requirements. Ensure the through-hole footprint matches the target PCB design constraints before finalizing procurement.

Selection Notes

Select this component when high current capacity is required alongside effective common mode noise attenuation. The low DCR minimizes power loss in high-current paths. Consider the physical size and through-hole mounting style against available PCB real estate and assembly methods compared to surface-mount alternatives.

Part Context

The TCK-103 belongs to the TCK series of power inductors from Traco Power. This series focuses on EMC chokes designed for robust performance in demanding environments. The component is categorized under power inductors and EMC chokes, distinct from general-purpose signal inductors.
