CST206-1A

Overview

The Triad Magnetics CST206-1A is a non-invasive current sense transformer designed for through-hole mounting. It features a solid core with a 9.14 mm aperture and PC pin termination. Key electrical parameters include a current rating of 110 A, a turns ratio of 100:1, and an inductance of 14 mH. The device operates within a frequency range of 20 kHz to 200 kHz, with a maximum DC resistance of 580 mOhm and an ET value of 2000 Vµs. 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
• Optimized for high-frequency switching power supply applications
• Through-hole PC pin termination for secure board mounting

Applications

• Switching power supply current sensing
• Power converter feedback loops
• Overcurrent protection circuits

Procurement Notes

Verify the specific suffix (e.g., -B) if required, as standard listings may vary by distributor. Confirm RoHS compliance status via the manufacturer datasheet before integration. Ensure the 110 A primary current rating aligns with peak load requirements. Check lead times as manufacturing schedules can impact availability. Validate physical footprint compatibility with PCB layout constraints.

Selection Notes

Select this component when a 100:1 ratio and 110 A primary rating are necessary. The 20 kHz to 200 kHz bandwidth suits typical SMPS frequencies. Consider the 9.14 mm hole size for busbar or wire gauge fit. Compare against the CST206-3A if a different ratio or higher inductance is needed. Ensure thermal management supports continuous operation at rated currents.

Part Context

Part of the CST206 series from Triad Magnetics, focusing on current sensing transformers. This series provides non-invasive monitoring solutions for power electronics. The CST206-1A specifically targets applications requiring robust through-hole construction and high current handling capabilities within a compact form factor.

Replacement Considerations

The CST206-3A offers a 300:1 ratio and 130 mH inductance but shares similar physical dimensions. Verify that the altered turns ratio does not affect signal conditioning circuitry. No other direct substitutes are confirmed in public documentation.
