TCK-156

Fixed Inductors Overview

The Traco Power TCK-156 is a fixed surface-mount wirewound inductor designed for power electronics applications. It features an inductance of 22 µH with a tolerance of ±20% and a maximum DC resistance of 180 mΩ. The component supports a rated current of 1.1 A and operates within a temperature range of -40°C to +125°C. Its non-standard package dimensions are 5.80 mm in length, 5.20 mm in width, and 3.70 mm in height maximum.

Fixed Inductors Feature Summary

• Unshielded wirewound construction for high-current handling
• Surface mount installation for automated assembly
• Wide operating temperature range suitable for industrial environments

Fixed Inductors Applications

• DC-DC converter input/output filtering
• Power supply output stages
• General-purpose energy storage in switching circuits

Fixed Inductors Procurement Notes

Verify the manufacturer part number TCK-156 against official Traco Power documentation to ensure authenticity. Confirm that the received components match the specified 22 µH inductance and 1.1 A current rating. Check for physical damage on the non-standard package before integration into PCB designs.

Fixed Inductors Selection Notes

Select this component when a 22 µH unshielded inductor is required for surface-mount layouts. Ensure the design accommodates the 1.1 A current rating without saturation. Verify that the non-standard footprint matches the PCB land pattern. Consider thermal management given the 180 mΩ DCR at higher ambient temperatures.

Fixed Inductors Part Context

The TCK-156 belongs to the Traco Power fixed inductor portfolio, which provides passive components for power conversion systems. These inductors complement active devices like DC-DC converters by managing ripple currents and stabilizing voltage levels in compact electronic assemblies.

Fixed Inductors Replacement Considerations

No public substitute part numbers are documented for the TCK-156. Evaluate alternative inductors based on matching 22 µH inductance, 1.1 A current rating, 180 mΩ DCR, and compatible surface-mount dimensions.
