CST206-1T-B

Overview

The Triad Magnetics CST206-1T-B is a board-mount current sense transformer designed for switching power supply applications. It features a toroidal encapsulated core with a 14 mH inductance and a 100:1 turns ratio. The device supports a primary current rating of 110 A and operates within a frequency range of 20 kHz to 200 kHz. Secondary coil resistance is specified at a maximum of 580 mOhms. It utilizes a radial through-hole mounting style with dimensions of 27.3 mm length, 10.16 mm width, and 31.11 mm height.

Feature Summary

• Non-invasive solid-core design for accurate current detection
• Encapsulated toroidal construction for reliability
• Optimized for high-frequency switching power supply environments

Applications

• Switching power supply current sensing
• Power management circuit monitoring
• Primary side current feedback loops

Procurement Notes

Verify the specific suffix 'B' against the manufacturer datasheet to confirm exact secondary resistance and tolerance specifications. Ensure the ordering part number matches the required current rating and frequency range for the target application. Confirm that the through-hole package dimensions are compatible with the intended PCB layout constraints.

Selection Notes

Select this component when a 110 A primary current capacity and 100:1 transformation ratio are required. The 20 kHz to 200 kHz operating range suits typical switch-mode power converter frequencies. Consider the physical size and through-hole termination method during mechanical integration planning.

Part Context

This model belongs to the CST206 series of current sense transformers from Triad Magnetics. The series is engineered for robust performance in power electronics. The CST206-1T-B variant specifically addresses high-current sensing needs with a 110 A rating, distinguishing it from lower-rated siblings like the CST206-3A-B which handles 70 A.

Replacement Considerations

Direct substitutes within the same series include CST206-1A-B and CST206-1T. Verify that alternative variants maintain identical electrical parameters such as inductance, turns ratio, and current ratings before substitution.
