ECSTA1V0805-1070-R

Overview

The ECSTA1V0805-1070-R is a surface-mount current sense transformer from Eaton Electronics, designed for board-level integration. It features a turns ratio of 70:1 and supports a primary current rating of 10 A. The component exhibits an inductance of 980 µH with a primary resistance of 700 mΩ and a secondary resistance of 4.75 Ω. Operating within a frequency range of 50 kHz to 1 MHz, it meets AEC-Q200 qualification standards. The physical dimensions are 8.38 mm in length, 8.00 mm in width, and 5.5 mm in height, suitable for automated SMT assembly processes.

Feature Summary

Provides galvanic isolation between primary and secondary circuits for accurate current monitoring
Engineered for high-frequency operation up to 1 MHz with stable magnetic coupling
Qualified for automotive applications under AEC-Q200 reliability standards

Applications

Automotive power management systems requiring isolated current feedback
DC-DC converter output current sensing
Motor drive protection circuits

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with design requirements. Confirm that the AEC-Q200 certification status remains valid for the intended automotive application scope. Check for any updated handling or soldering guidelines provided by Eaton Electronics prior to procurement.

Selection Notes

Select this component when a 70:1 isolation ratio and 10 A primary current capacity are required. Ensure the operating frequency falls within the 50 kHz to 1 MHz range for optimal performance. Consider the 980 µH inductance value for circuit stability and the physical footprint constraints of the 0805-style package during PCB layout.

Part Context

This part belongs to the ECSTA series of surface-mount current transformers from Eaton Electronics. The series is characterized by its compact form factor and suitability for high-reliability environments. It serves as a specialized solution for applications needing precise current measurement without direct electrical contact between high-voltage and low-voltage sides.
