TCK-050

Overview

The TCK-050 is a through-hole common mode choke manufactured by Traco Power. It features an inductance of 325 µH with a tolerance of ±35% at 100 kHz and 100 mV. The component has a maximum DC resistance of 35 mΩ and a rated current of 3.3 A. It operates within a temperature range of -40°C to +105°C.

Feature Summary

• High current rating suitable for demanding applications
• Low DC resistance ensuring minimal signal attenuation
• Through-hole mounting technology

Applications

• Common mode noise filtering
• Signal integrity protection
• Power supply input stages

Procurement Notes

Verify the specific datasheet version and mechanical dimensions against the target PCB footprint before procurement. Confirm that the rated current of 3.3 A meets the circuit requirements under all operating conditions. Ensure the inductance value aligns with the intended filtering frequency range. Check compliance documentation if required for the final assembly.

Selection Notes

Select this component when a high-current common mode choke is needed for through-hole assembly. The 325 µH inductance provides effective filtering for specific noise frequencies. Consider the 3.3 A current rating to prevent saturation in high-power lines. Evaluate the thermal performance within the -40°C to +105°C range for environmental suitability.

Part Context

The TCK-050 belongs to Traco Power's passive component portfolio, specifically designed for electromagnetic interference suppression. Unlike their active DC/DC converters, this part serves as a filter element. It complements power conversion systems by mitigating common mode noise, ensuring cleaner signal transmission in industrial and commercial electronic designs.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing board layouts and electrical specifications before considering alternative components from other manufacturers.
