Fixed Inductors datasheet and documents for TCK-121

TCK-121

Fixed Inductors Overview

The TCK-121 is a fixed inductor from Traco Power designed for surface-mount applications. It features an inductance of 15 µH and a maximum operating current of 700 mA. The component has a DC resistance of 570 mOhm and operates within a temperature range of -40°C to 125°C. Its physical dimensions are 3.6 mm in length, 2.7 mm in width, and 1.55 mm in depth.

Fixed Inductors Feature Summary

Surface-mount design suitable for automated PCB assembly processes
Fixed inductance value optimized for EMC filtering in DC/DC converter circuits
Robust construction supporting high operating temperatures up to 125°C

Fixed Inductors Applications

EMC chokes for DC/DC converters
Power supply input/output filtering
General-purpose signal conditioning in electronic circuits

Fixed Inductors Procurement Notes

Verify the specific package type and tolerance requirements against your schematic before ordering. Confirm that the 700 mA current rating meets the peak load demands of your application. Ensure the 570 mOhm resistance aligns with your efficiency targets. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.

Fixed Inductors Selection Notes

Select this component when a compact, surface-mount inductor is required for power line filtering. The 15 µH value is suitable for standard switching frequencies found in many DC/DC topologies. Consider the 700 mA saturation current limit to prevent performance degradation under heavy loads. The small footprint makes it ideal for space-constrained board layouts.

Fixed Inductors Part Context

This component belongs to Traco Power's passive component portfolio, specifically focusing on power inductors. Unlike their active DC/DC converters, these inductors serve as essential building blocks for shaping current waveforms and suppressing noise in power electronics systems.
