ECST1V0805-1050-R

Overview

The ECST1V0805-1050-R is a surface-mount current sense transformer from Eaton Electronics, designed for invasive AC current measurement. It features a primary current rating of 10 A and a turns ratio of 50:1. The component exhibits an inductance of 500 uH with a secondary coil resistance of 1.85 Ohms. It operates within a frequency range of 50 kHz to 1 MHz and is qualified under the AEC-Q200 standard. The physical dimensions are 8.38 mm in length, 8 mm in width, and 5.5 mm in height, supporting operation between -40 C and +125 C.

Feature Summary

• Provides galvanic isolation for invasive AC current sensing applications
• Surface-mount construction facilitates automated PCB assembly processes
• Automotive-grade qualification ensures reliability in demanding environments

Applications

• Invasive AC current monitoring in electronic circuits
• Power supply feedback loops requiring isolated sensing
• Automotive electronics systems meeting AEC-Q200 standards

Procurement Notes

Verify the specific ordering suffix matches the required reel or cut tape configuration. Confirm that the AEC-Q200 qualification aligns with target automotive or industrial specifications. Ensure the 10 A primary rating and 500 uH inductance meet circuit design requirements before finalizing procurement orders.

Selection Notes

Select this component when invasive AC current sensing is required with high isolation. The 50:1 turns ratio suits applications needing scaled-down secondary signals. Consider the 8.38 x 8 mm footprint for space-constrained designs. Verify thermal management capabilities given the +125 C maximum operating temperature limit.

Part Context

This part belongs to the ECSTA series of current transformers from Eaton Electronics. It is distinct from resistive current sense components like the MSMA series. The device utilizes magnetic coupling rather than voltage drop for measurement, offering inherent isolation between primary and secondary circuits.
