Current Sense Transformers Procurement Notes

Verify the specific suffix '070' indicates the 1:70 turns ratio configuration. Confirm AEC-Q200 qualification status if automotive compliance is required. Check mechanical dimensions against PCB footprint requirements due to the 5.5mm maximum height constraint. Ensure compatibility with reflow soldering profiles suitable for surface mount components.

Current Sense Transformers Selection Notes

Select this component when invasive current sensing is required for currents up to 20A. Consider the 1:70 ratio for appropriate signal scaling in downstream circuitry. Evaluate the 980 µH inductance value for low-frequency response needs. Verify that the 0.75mOhm primary resistance meets thermal dissipation limits in the target application environment.

Current Sense Transformers Part Context
