Procurement Notes
Verify the exact electrical specifications against the manufacturer's datasheet before integration, as parameters such as inductance and resistance are critical for circuit performance. Ensure the through-hole package dimensions align with the PCB layout requirements. Confirm that the operating frequency range matches the system's switching speed to maintain signal integrity and measurement accuracy during procurement.
Selection Notes
Select this component when high-current sensing is required in high-frequency environments. The 110 A rating suits robust power stages, while the 20-200 kHz bandwidth covers common SMPS frequencies. Consider the physical core size and through-hole constraints during mechanical design. Compare against similar series parts if different current or frequency ranges are needed for the specific application.
Part Context
This part belongs to the CST206 series of high-frequency current sense transformers from Triad Magnetics. These components are engineered specifically for detecting current in conductors within power electronics. The series offers various configurations to suit different current and frequency requirements in modern switching power supply designs.
Replacement Considerations
The CST206-1T-B is a related variant within the same product family. Verify compatibility regarding current ratings and frequency response before substitution. Other models in the CST206/CST306 series may offer alternative specifications suitable for different power levels.
