Current Sense Transformers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and electrical characteristics. Confirm that the through-hole package dimensions match the target PCB footprint requirements. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the rated current and frequency range align with the system's operational parameters before procurement.

Current Sense Transformers Selection Notes

Select this component when a through-hole current sense transformer is required for high-current applications up to 20 A. Consider the 20 mH inductance and 100 Ohm primary resistance for impedance matching in feedback circuits. Evaluate the 20 kHz to 200 kHz frequency range against the switching frequency of the power supply design. Compare physical dimensions against available board space constraints.
