CST206-2A

Overview

The Triad Magnetics CST206-2A is a board-mount current sensing transformer designed for high-frequency applications. It features a through-hole radial termination style and operates within a frequency range of 20 kHz to 200 kHz. The component has an inductance of 56 mH, a maximum DC resistance of 3.5 Ohms, and a turns ratio of 200:1. It supports a current rating of 80 A and utilizes a solid core construction. Physical dimensions are 27.31 mm in length, 10.16 mm in width, and a maximum height of 31.12 mm.

Feature Summary

• Non-invasive solid core construction for reliable current sensing
• Operates effectively across a wide high-frequency range
• Constructed with UL rated materials for thermal stability

Applications

• High-frequency power supply circuits
• Current monitoring systems
• Industrial control equipment

Procurement Notes

Verify the specific manufacturer part number against official Triad Magnetics documentation to ensure compatibility with design requirements. Confirm that the 200:1 turns ratio and 80 A current rating align with the target application's electrical specifications. Check for any updated datasheet revisions that may affect mechanical or electrical performance characteristics before finalizing procurement.

Selection Notes

Select this component when a non-invasive current sensing solution is required for frequencies between 20 kHz and 200 kHz. Ensure the PCB layout accommodates the through-hole radial package dimensions of approximately 27.31 mm by 10.16 mm. Consider the 56 mH inductance and 3.5 Ohm resistance values for circuit impedance matching. Verify that the operating environment does not exceed the UL rated material temperature limits.

Part Context

The CST206-2A belongs to the CST206 series of current sense transformers manufactured by Triad Magnetics. This series is characterized by encapsulated toroidal cores and robust construction suitable for demanding electronic environments. The model represents a specific variant within the family optimized for 80 A current handling and 200:1 transformation ratios.

Replacement Considerations

The CST206-2A-B is a related variant within the same product line. Verify if the alternative model meets the specific 200:1 ratio and 200 kHz upper frequency limit required by the design, as variations exist within the series.
