ECSTA1V1308-1030-R

Overview

The ECSTA1V1308-1030-R is a surface-mount current sense transformer from Eaton Electronics, designed for high-frequency circuit monitoring. It features a 30:1 turns ratio and supports a maximum primary current of 15A. The component operates within a frequency range of 50 kHz to 1 MHz. Key electrical specifications include a primary inductance of 500 uH, a primary resistance of 3.9 mOhms, and a secondary resistance of 320 mOhms. It is qualified under AEC-Q200 standards and functions reliably between -40 C and +125 C.

Feature Summary

• Provides galvanic isolation while measuring AC or pulsed DC currents
• Optimized for high-frequency operation up to 1 MHz
• Automotive-grade reliability with AEC-Q200 qualification
• Compact surface-mount design for automated assembly

Applications

• Power transmission and distribution systems
• Industrial machinery motor control
• Electrical equipment protection circuits
• Inverter and converter current sensing

Procurement Notes

Verify the specific suffix '-R' indicates reel packaging when ordering. Confirm that the 30:1 turns ratio matches the target circuit requirements. Ensure the PCB footprint aligns with the SMD package dimensions. Check AEC-Q200 compliance if automotive application is required. Validate operating temperature range against environmental conditions.

Selection Notes

Select this component when a 30:1 ratio is necessary for signal conditioning. Consider the 15A primary current limit for load capacity. Evaluate the 500 uH inductance for low-frequency response needs. Compare secondary resistance impact on downstream amplifier loading. Assess thermal performance at maximum operating temperatures.

Part Context

This part belongs to the ECSTA series of current sense transformers. It shares the 1V1308 physical form factor with other variants like the 1040-R. The series offers multiple turns ratios for different sensing applications. Eaton Electronics designs these components for robust industrial and automotive environments.

Replacement Considerations

Direct substitutes include ECST1V1308-1040-R for a 40:1 ratio. Other ECSTA variants offer different turns ratios such as 70:1 or 100:1. Verify pinout compatibility before substitution. Ensure equivalent inductance and frequency response characteristics.
