CST206-2A-B

Overview

The Triad Magnetics CST206-2A-B is a through-hole current sense transformer designed for high-frequency applications. It features a 200:1 turns ratio and an inductance of 56 mH. The component supports a primary current rating of 80 A with a secondary DC resistance of 3.5 ohms. Operating within a frequency range of 20 kHz to 200 kHz, it utilizes a solid core construction. Physical dimensions are 27.31 mm in length, 10.16 mm in width, and 31.12 mm in height.

Feature Summary

• Non-invasive solid core design for direct conductor insertion
• High-frequency operation capability up to 200 kHz
• Through-hole radial termination for PCB mounting

Applications

• Switch-mode power supply (SMPS) current sensing
• Inverter and motor drive control circuits
• Overcurrent protection systems

Procurement Notes

Verify the specific suffix designation against official Triad Magnetics documentation to confirm electrical parameters. Ensure the required primary current rating aligns with the 80 A specification. Confirm that the operating frequency range meets the application requirements. Check for RoHS compliance status if environmental regulations apply. Validate physical footprint compatibility with the target printed circuit board layout.

Selection Notes

Select this component when a high turns ratio is required for precise current monitoring in high-power environments. The solid core design eliminates air gaps, potentially improving magnetic coupling efficiency. Consider the through-hole mounting style for mechanical stability in high-vibration applications. Evaluate the thermal performance relative to the expected continuous primary current load.

Part Context

This part belongs to the CST206 series of current transformers from Triad Magnetics. The series is characterized by toroidal core constructions suitable for general-purpose current sensing. Variants within the series differ primarily in turns ratios and current ratings to accommodate diverse circuit requirements.

Replacement Considerations

Triad Magnetics CST206-2A is a related variant within the same series. Verify if the specific electrical tolerances and manufacturing revisions match the original design requirements before substitution.
