ECSTA1V1308-1150-R

Overview

The ECSTA1V1308-1150-R is an automotive-grade surface-mount current sense transformer from Eaton Electronics. It features a 1:150 turns ratio and operates within a frequency range of 50 kHz to 1 MHz. The component has a maximum primary inductance of 12.6 mH, with primary and secondary resistances of 3.9 mOhms and 6.5 Ohms, respectively. Rated for 15 A, it meets AEC-Q200 standards and functions between -40°C and +125°C.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q200 qualification standards
• Surface-mount design optimized for high-frequency current sensing applications
• High isolation capability through dedicated primary and secondary windings

Applications

• Automotive powertrain control systems
• On-board charger current monitoring
• DC-DC converter feedback loops

Procurement Notes

Verify the specific suffix and package variant against the official Eaton datasheet to ensure compatibility with your PCB footprint and thermal requirements. Confirm that the AEC-Q200 certification aligns with your vehicle's quality standards. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components and ensure traceability.

Selection Notes

Select this component when high-frequency current sensing is required in space-constrained automotive environments. The 1:150 ratio suits applications needing precise signal attenuation for downstream ADC processing. Ensure the operating temperature range covers your system's worst-case thermal conditions and that the SMT package fits the assembly constraints.

Part Context

This part belongs to the ECSTA1V1308 series of current sense transformers designed by Eaton Electronics. The series provides various turns ratios and electrical characteristics tailored for automotive electronics. These components are engineered to replace traditional shunt resistors where galvanic isolation and reduced power loss are critical design factors.

Replacement Considerations

Direct substitutes include other models within the ECSTA1V1308 family with matching 1:150 ratios and similar physical dimensions. Verify that any alternative maintains the same AEC-Q200 qualification and frequency response characteristics.
