Procurement Notes

Verify the specific suffix '1200' corresponds to the required 200:1 turns ratio before ordering. Confirm that the 15 A primary current rating aligns with the target application's peak load requirements. Ensure the operating frequency range of 50 kHz to 1 MHz matches the system switching speed. Check for any specific automotive qualification standards required by the end product.

Selection Notes

Select this component when a high turns ratio is necessary for sensitive current detection in automotive or industrial settings. The 200:1 ratio allows for measuring high primary currents using lower secondary side voltages. Consider the 500 Vac isolation rating for safety-critical circuits. The surface mount package facilitates automated assembly processes.

Part Context

This part belongs to the ECST1V1308 series of current sense transformers from Eaton Electronics Division. The series offers various turns ratios, indicated by the middle digits in the part number. This specific model is optimized for automotive applications, distinguishing it from commercial-grade variants within the same physical footprint family.

Replacement Considerations

Direct substitutes must match the 200:1 turns ratio, 15 A current rating, and 1308 SMD package dimensions. Verify that alternative components meet the same automotive grade specifications and isolation voltage ratings to ensure functional equivalence.
