ECSTA1V0703-1020-R

Overview

The ECSTA1V0703-1020-R is a surface-mount current sensing transformer manufactured by Eaton Electronics. It features a 1:20 turns ratio and supports a primary current rating of 9 A. The device operates within a frequency range of 50 kHz to 1 MHz. Electrical characteristics include a maximum primary inductance of 0.053 µH, a primary DC resistance of 1.5 mΩ, and a secondary DC resistance of 0.42 Ω. The component is qualified under the AEC-Q200 standard and utilizes SMD/SMT termination styles for board mounting.

Feature Summary

Provides precise current sensing with a fixed 1:20 turns ratio
Designed for high-frequency operation between 50 kHz and 1 MHz
Qualified for automotive applications via AEC-Q200 standards
Utilizes surface-mount technology for automated assembly

Applications

Automotive power electronics monitoring
High-frequency switching power supply feedback loops
Current protection circuits in electric vehicle systems
Battery management system (BMS) current sensing

Procurement Notes

Verify that the specific suffix matches the required tolerance and packaging configuration. Confirm that the operating frequency aligns with the 50 kHz to 1 MHz specification. Ensure the PCB footprint accommodates the SMD/SMT termination style. Check for AEC-Q200 compliance requirements if deploying in automotive environments. Validate primary current ratings against circuit load conditions.

Selection Notes

Select this component when a fixed 1:20 transformation ratio is required for signal isolation. Consider the 9 A primary current limit for high-power applications. Evaluate the 50 kHz to 1 MHz bandwidth against switching frequencies. Assess the low primary inductance for fast transient response needs. Verify compatibility with surface-mount assembly processes.
