Current Sense Transformers Procurement Notes

Verify the specific inductance value against the latest manufacturer datasheet, as conflicting data exists between 180 uH and 2000 uH in public listings. Confirm the package dimensions match the required footprint, noting variations in listed height measurements. Ensure the supplier provides RoHS3 compliance documentation. Cross-reference the part number suffix to confirm the exact winding configuration and tolerance specifications required for the design.

Current Sense Transformers Selection Notes

Select this component when galvanic isolation is required for current monitoring in high-frequency environments. The 1:100 turns ratio suits applications needing precise signal attenuation from primary to secondary sides. Consider the 20 A current limit and thermal performance for the expected load conditions. The surface-mount format facilitates automated assembly. Verify that the 1 MHz operating range aligns with the system's switching frequency to ensure accurate signal fidelity.
