Procurement Notes

Verify the specific suffix '-1020-R' against the manufacturer datasheet to confirm the 20:1 turns ratio and 15 A rating. Ensure the ordering quantity aligns with the reel packaging specifications provided by Eaton. Confirm that the AEC-Q200 qualification meets the specific automotive grade requirements of the target application before finalizing procurement.

Selection Notes

Select this component when a 20:1 isolation ratio and 15 A primary current capacity are required. The wide operating temperature range suits harsh automotive environments. Consider the physical dimensions and SMT footprint compatibility during layout design. Verify that the 50 kHz to 1 MHz bandwidth matches the switching frequency of the target power circuit.

Part Context

This part belongs to the ECSTA series of current sense transformers from Eaton Electronics Division. The series provides various current ratings and form factors for different power levels. The '1308' designation indicates the specific package size and core geometry used for higher current handling compared to smaller variants in the lineup.

Replacement Considerations

Direct substitutes must match the 20:1 ratio, 15 A rating, and SMD footprint. Cross-reference Eaton's updated ECSTA series listings for potential newer revisions. Verify that any alternative maintains AEC-Q200 certification if automotive use is intended.
