Procurement Notes
Verify the specific datasheet version from Traco Power or authorized distributors to confirm mechanical dimensions and electrical tolerances. Ensure the selected component matches the required 1.7A current rating and 500V voltage specification for your circuit design. Cross-reference the package type with your PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring robust common mode noise attenuation for dual-line configurations. Consider the 100mΩ DCR impact on power loss and the 1.7A current limit relative to your load requirements. Evaluate the thermal performance within the -40°C to 125°C range against your environmental conditions.
Part Context
The TCK-017 belongs to Traco Power's passive component portfolio, specifically designed as a common mode choke. It complements active power conversion solutions by addressing electromagnetic compatibility challenges. This component is part of a broader range of filters intended to enhance system reliability in noisy environments.
Replacement Considerations
Consult official Traco Power documentation for verified substitute part numbers. Ensure any replacement maintains identical inductance, current rating, and physical dimensions to guarantee compatibility with existing designs.
