Overview
The TCK-122 is a common mode choke from Traco Power, designed for use with isolated DC/DC converters. It features an inductance of 5 µH ±40% at 10 kHz and 50 mV. The component has a maximum DC resistance (DCR) of 120 mΩ. It supports a rated current of 1.5 A max and a rated voltage of 500 VDC max.
Feature Summary
- Provides common mode noise suppression for DC/DC converter applications
- Designed specifically for use with Traco isolated DC/DC converters
- Offers high insulation capability with a rated voltage of 500 VDC
Applications
- EMC filtering for DC/DC converters
- Common mode noise suppression in industrial electronics
- Power supply input/output stages requiring EMI reduction
Procurement Notes
Verify the specific datasheet version to confirm the rated voltage specification, as some sources indicate 500 VDC while others may reference lower values. Ensure the inductance tolerance of ±40% meets the circuit requirements. Confirm the package type matches the PCB layout constraints before ordering.
Selection Notes
Select this component when common mode noise attenuation is required for Traco power supplies. The 5 µH inductance provides effective filtering at standard switching frequencies. The 1.5 A current rating suits low-power converter interfaces. Verify the 120 mΩ DCR does not cause excessive voltage drop in the application.
Part Context
The TCK-122 belongs to the TRACOPOWER TCK series of common mode chokes. These components are passive filters intended to suppress electromagnetic interference. They complement Traco's range of isolated DC/DC converters by ensuring compliance with EMC standards in sensitive electronic environments.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult Traco Power technical support for equivalent components if the TCK-122 is unavailable.
