Procurement Notes
Verify the specific suffix HF against the manufacturer's latest documentation to confirm compliance status and material composition. Ensure the ordering part number matches the required current rating and inductance specifications exactly. Cross-reference the datasheet revision date to confirm the validity of electrical parameters before finalizing procurement orders.
Selection Notes
Select this component when a surface-mount solution is required for high-current sensing up to 80 A. The 1:200 ratio provides a balanced output for downstream signal conditioning. Consider the 0.08 mOhm primary resistance for thermal management in high-efficiency designs. Verify that the 25 mH inductance meets the bandwidth requirements of the target application circuit.
Part Context
This part belongs to the T10135 series of current sense transformers from ITG Electronics. The series offers various turn ratios and current ratings tailored for different power levels. The T10135A-200HF specifically addresses applications needing robust surface-mount capabilities with defined electrical characteristics for reliable performance in compact electronic assemblies.
Replacement Considerations
The T10135B-200HF is a related variant within the same product family. Note that the B-series may differ in current rating or resistance values compared to the A-series. Verify exact electrical equivalence before substitution.
