ECSTA1V0805-1040-R

Overview

The ECSTA1V0805-1040-R is a surface-mount current sense transformer from Eaton Electronics, designed for high-frequency applications. It features a 40:1 turns ratio and supports a primary current rating of 10 A. The component exhibits an inductance of 320 µH with a primary resistance of 700 mΩ and a secondary resistance of 1.14 Ω. Operating within a frequency range of 50 kHz to 1 MHz, it is qualified under the AEC-Q200 standard. The device utilizes an EE5.0 SMT package measuring 8.38 mm in length, 8 mm in width, and 5.5 mm in height, suitable for automated assembly processes.

Feature Summary

AEC-Q200 qualified for automotive reliability standards
EE5.0 surface-mount package design for compact integration
Low DC resistance characteristics on both primary and secondary windings

Applications

Automotive power supply current monitoring
High-frequency switching mode power supply feedback loops
Industrial motor drive current sensing

Procurement Notes

Verify that the specific part number matches the required electrical parameters, particularly the 40:1 turns ratio and 10 A current rating. Confirm compliance with AEC-Q200 requirements if the application involves automotive systems. Ensure the ordering suffix corresponds to the desired packaging format, such as cut tape or reel, to align with manufacturing equipment capabilities.

Selection Notes

Select this component when a compact surface-mount solution is required for current sensing in high-frequency circuits. The EE5.0 package offers a small footprint suitable for space-constrained designs. Consider the 50 kHz to 1 MHz operating range to ensure compatibility with the system's switching frequency. Verify thermal management needs given the maximum operating temperature of +125 C.
