CST206-2T-B

Overview

The Triad Magnetics CST206-2T-B is a current sense transformer designed for through-hole mounting. It features a solid core construction with radial termination. Key electrical parameters include an inductance of 56 mH, a turns ratio of 200:1, and a maximum secondary resistance of 3.5 ohms. The device supports a frequency range of 20 kHz to 200 kHz and handles a current rating of 80 A. 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 accurate current sensing
• High-frequency operation capability up to 200 kHz
• Through-hole radial termination for PCB integration

Applications

• Switch-mode power supply current monitoring
• Inverter and motor drive control circuits
• Industrial power management systems

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's latest datasheet to confirm pinout and tolerance specifications. Ensure the selected component matches the required 80 A current rating and 56 mH inductance for the target application. Cross-reference physical dimensions with the PCB footprint to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when high-frequency current sensing is required within the 20 kHz to 200 kHz range. The 200:1 turns ratio suits applications needing precise signal isolation from primary currents up to 80 A. Consider the through-hole package type if surface-mount alternatives are unsuitable for the thermal or mechanical constraints of the design.

Part Context

This part belongs to the CST206 series of current transformers from Triad Magnetics. The series offers various configurations tailored for different current ratings and inductance values. The CST206-2T-B specifically addresses high-current applications requiring robust isolation and wide bandwidth performance in power electronics environments.

Replacement Considerations

Direct substitutes may include other Triad Magnetics models within the CST206 family that match the 200:1 ratio and 80 A rating. Verify equivalent electrical parameters such as 56 mH inductance and 3.5 ohm resistance before substitution.
