Overview
The TCK-090 is a common mode choke manufactured by Traco Power, designed for use with isolated DC-DC converters. It features an inductance of 470 µH at 10 kHz and supports a maximum rated current of 1 A. The component has a maximum DC resistance of 60 mΩ and a voltage rating of 500 VDC. Its physical dimensions are 11.8 mm in length, 11.8 mm in width, and 5 mm in height.
Feature Summary
- Provides common mode noise suppression for power lines
- Compatible with Traco isolated DC-DC converter series
- Compact surface mount design for space-constrained applications
Applications
- Noise filtering in industrial DC-DC converter circuits
- EMC compliance enhancement for sensitive electronic loads
- Power line conditioning in machine tools and process systems
Procurement Notes
Verify the specific application requirements against the 1 A current rating and 500 VDC voltage limit before procurement. Confirm that the 470 µH inductance value meets the electromagnetic interference suppression needs of the target circuit. Ensure compatibility with the intended Traco converter model as specified in official documentation.
Selection Notes
Select this component when integrating Traco isolated DC-DC converters requiring common mode noise reduction. Consider the 1 A current capacity and 60 mΩ DC resistance for efficiency calculations. The compact 11.8 x 11.8 x 5 mm footprint suits dense PCB layouts where standard through-hole chokes may not fit.
Part Context
The TCK-090 belongs to the TCK series of common mode chokes from Traco Power. This series is specifically engineered to complement Traco's range of isolated DC-DC converters, ensuring optimal performance and reliability in industrial environments. The component addresses EMC challenges inherent in switching power supplies.
Replacement Considerations
No public confirmed substitute part numbers are available for the TCK-090. Users should consult Traco Power technical support or datasheets for potential alternatives if this specific component is unavailable.
