Procurement Notes

Verify the specific ordering suffix matches the required turns ratio and electrical parameters. Confirm that the AEC-Q200 qualification status aligns with target automotive application requirements. Ensure soldering procedures adhere to thermal limits, as manual hand soldering is generally not recommended. Check for RoHS compliance documentation if environmental regulations apply to the end product.

Selection Notes

Select this component when a 1:60 isolation ratio and 7 A primary current capacity are required. Consider the 295 uH inductance value for filtering and signal integrity needs within the 50 kHz to 1 MHz bandwidth. Evaluate the physical dimensions against available PCB real estate. Verify compatibility with surface mount reflow processes rather than through-hole or manual soldering techniques.

Part Context

This part belongs to the ECSTA series of current sense transformers manufactured by Eaton Electronics. The series provides isolated current measurement solutions for various industrial and automotive applications. The ECSTA1V0504-1060-R specifically addresses high-frequency sensing needs with a standardized SMD package. Similar parts in the family may offer different turns ratios or current ratings while maintaining comparable form factors.

Replacement Considerations

The ECSTA1V0504-1050-R is a related variant offering a 50:1 turns ratio instead of 1:60. Both share similar physical dimensions and current ratings but differ in transformation ratio. Ensure circuit compensation networks are adjusted if substituting between different ratio variants.
