Overview
The TCK-100 is a wirewound power inductor from TRACO Power, designed as an EMC choke for DC/DC converters. It features an unshielded construction with a 3.3 uH nominal inductance and a 20% tolerance. The component supports a maximum DC current of 3.3 A and exhibits a maximum DC resistance of 300 mOhms. Measuring 4.5 mm in length, 4 mm in width, and 3.2 mm in height, it utilizes SMD/SMT mounting on a PCB. Testing is conducted at a frequency of 100 kHz.
Feature Summary
- Wirewound core construction for stable inductance performance
- Unshielded design suitable for general EMC filtering applications
- Surface-mount technology (SMD/SMT) implementation for automated assembly
Applications
- Electromagnetic interference (EMI) suppression in DC/DC converter circuits
- Common mode noise filtering in power supply input stages
- Signal integrity enhancement in industrial electronic systems
Procurement Notes
Verify the specific datasheet revision to confirm exact electrical tolerances and thermal ratings before integration. Ensure the PCB footprint matches the 4.5 x 4 mm dimensions. Confirm RoHS compliance status through official manufacturer documentation rather than distributor summaries. Validate that the 3.3 A current rating aligns with the system's peak load requirements without saturation.
Selection Notes
Select this component when an unshielded wirewound inductor is required for cost-effective EMI filtering in compact designs. The 3.3 uH value targets specific switching frequencies common in DC/DC topologies. Consider the 300 mOhm DCR impact on overall efficiency. The unshielded nature may require careful layout planning to minimize magnetic coupling with nearby sensitive traces compared to shielded alternatives.
Part Context
The TCK series by TRACO Power comprises power inductors intended for use in telecommunications and industrial equipment. These components serve as critical passive elements for stabilizing current and filtering noise in regulated power conversion architectures. The TCK-100 specifically addresses needs for moderate current handling in space-constrained printed circuit board environments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing requires matching 3.3 uH inductance, 3.3 A current rating, and compatible SMD package dimensions.
