Procurement Notes
Verify the specific suffix against official Triad Magnetics documentation to confirm electrical characteristics such as inductance and current rating. Ensure the package type matches the required footprint. Confirm RoHS compliance status directly from the manufacturer's latest datasheet before finalizing procurement specifications.
Selection Notes
Select this component when precise current sensing is required in high-frequency switching environments. The 80 A rating and 200:1 ratio suit applications needing accurate isolation between primary conductors and secondary control circuitry. Evaluate thermal performance and core saturation limits relative to peak load conditions.
Part Context
This part belongs to the CST206 series of high-frequency current sense transformers manufactured by Triad Magnetics. The series is engineered for compact board-mount implementations where space constraints and signal integrity are critical. These components provide galvanic isolation while maintaining accuracy across wide bandwidths.
Replacement Considerations
Triad Magnetics CST206-2A-B offers similar form factor but differs in electrical parameters including 3.5 Ohm resistance and 4000 Vµs voltage-time product.
