Procurement Notes
Verify the specific manufacturer part number TCK-067 against official Traco Power documentation to confirm electrical parameters and mechanical dimensions. Ensure compatibility with through-hole assembly processes and check for any recent design changes or obsolescence notices directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when designing circuits requiring robust common mode noise suppression for currents up to 7.5 A. Consider the 620 µH inductance value at 100 kHz for effective EMI filtering in standard frequency ranges. Evaluate the 25 mΩ DCR impact on system efficiency and ensure the 500 V DC rating meets the circuit's voltage requirements.
Part Context
The TCK-067 belongs to Traco Power's range of passive components used for signal integrity and power line conditioning. As a common mode choke, it complements active power conversion modules by mitigating conducted emissions. This component is typically utilized in conjunction with other filtering elements to meet stringent EMC standards in electronic equipment.
Replacement Considerations
Consult official Traco Power substitution guides for verified equivalent part numbers. Ensure any replacement maintains identical inductance, current rating, and dimensional constraints to preserve board layout and performance characteristics.
