Overview
The TCK-099 is a surface-mount common mode choke manufactured by Traco Power. It features an inductance of 4.7 µH at 100 kHz and supports a current rating of 5 A. The component has a two-line configuration with a DC resistance of 23.3 mΩ at 100 kHz. Its physical dimensions are 6.5 x 6.5 mm, and it operates within a temperature range of -40°C to +105°C. The product status is listed as obsolete.
Feature Summary
- Surface mount construction for automated PCB assembly
- Two-line configuration for differential signal filtering
- High current handling capability suitable for power line applications
Applications
- Electromagnetic interference suppression in electronic circuits
- Common mode noise reduction in data lines
- Power supply input filtering
Procurement Notes
Verify the obsolete product status before design finalization. Confirm availability through authorized distributors or secondary market suppliers. Ensure the surface mount footprint matches the target PCB layout. Check for RoHS compliance documentation if required by specific regulatory standards. Validate thermal performance within the specified operating temperature range during system integration.
Selection Notes
Select this component when a compact surface mount solution is required for common mode noise suppression. The 5 A current rating makes it suitable for moderate power applications. Consider the 4.7 µH inductance value for the intended frequency range. Verify that the 6.5 x 6.5 mm package fits within the available board space. Compare specifications with active series components if long-term supply stability is a priority.
Part Context
Traco Power produces passive components alongside their power supply modules. The TCK series includes various common mode chokes designed for EMC compliance. These components complement the company's broader portfolio of industrial and medical power solutions. The TCK-099 specifically addresses noise filtering needs in compact electronic designs.
Replacement Considerations
As the TCK-099 is obsolete, identify equivalent parts from other manufacturers offering similar inductance and current ratings. Verify pin compatibility and mechanical dimensions for direct replacement. Consult manufacturer datasheets for updated alternatives in the common mode choke category.
