Procurement Notes

Verify the specific suffix configuration against official Eaton documentation to ensure correct turns ratio and electrical characteristics. Confirm that the component meets AEC-Q200 requirements if deployed in automotive environments. Cross-reference the datasheet specifications for thermal limits and impedance values prior to integration to guarantee system compatibility.

Selection Notes

Select this component when a 50:1 current transformation ratio is required for high-frequency applications. Ensure the PCB layout accommodates surface-mount installation and supports the specified thermal operating range. Verify that the primary current rating of 15A aligns with the circuit's maximum load conditions to prevent saturation or performance degradation.

Part Context

This part belongs to the ECSTA series of board-mount current transformers from Eaton Electronics. The series offers various turns ratios and package sizes tailored for different current sensing needs. The ECSTA1V1308 variant specifically addresses applications requiring robust performance in compact surface-mount designs with defined automotive qualification standards.

Replacement Considerations

Compatible substitutes within the same family include ECSTA1V1308-1070-R (70:1 ratio) and ECSTA1V1308-1100-R (100:1 ratio). These alternatives share similar physical dimensions and mounting styles but differ in electrical transformation ratios. Verify that the alternative ratio matches the specific current sensing requirements of the target application.
