• High-frequency DC-DC converter feedback loops

Procurement Notes

Verify that the specific part number matches the required 50:1 turns ratio and 10 A rating for your design. Confirm AEC-Q200 compliance is necessary for your application's environmental requirements. Ensure the PCB footprint accommodates the specified 8.38 x 8 x 5.5 mm package dimensions. Check that the operating temperature range of -40 C to +125 C aligns with your system's thermal profile.

Selection Notes

Select this component when isolated current sensing is required in compact automotive or industrial designs. The 50:1 ratio suits applications where low-voltage secondary signals interface with standard ADCs. Consider the 500 µH inductance for filtering requirements in the signal path. The SMT package facilitates automated assembly processes. Evaluate the 1.85 Ohm secondary resistance against your burden resistor calculations.

Part Context

This transformer belongs to the ECSTA series of current sense transformers by Eaton Electronics. The series is engineered for surface-mount technology, offering a compact alternative to through-hole solutions. These components are specifically tailored for modern electronics requiring precise current measurement without direct electrical contact between high-voltage and low-voltage domains.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing PCB footprints if considering alternatives from other manufacturers.
