ECSTA1V1308-1040-R

Overview

The ECSTA1V1308-1040-R is a surface-mount current sense transformer from Eaton Electronics, designed for board-level integration. It features a 40:1 turns ratio and supports a maximum primary current of 15 A. The component operates within a frequency range of 50 kHz to 1 MHz and exhibits an inductance of 880 µH. Electrical characteristics include a primary DC resistance of 3.9 mΩ and a secondary DC resistance of 500 mΩ. It is qualified under the AEC-Q200 standard and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• EE8.3 SMT package design for compact board space
• Low DC resistance on both primary and secondary windings

Applications

• Automotive power electronics monitoring
• Current sensing in high-frequency switching circuits
• Board-level isolation in industrial power supplies

Procurement Notes

Verify that the specific suffix matches the required turns ratio, as variations exist within the series. Confirm AEC-Q200 qualification status if automotive compliance is mandatory. Ensure the selected variant aligns with the target operating frequency range and thermal requirements. Cross-reference the datasheet for precise electrical tolerances before finalizing the bill of materials.

Selection Notes

Select this component when a 40:1 ratio is required for current sensing applications. Consider the EE8.3 footprint constraints during layout design. Evaluate the 15 A current rating against peak load conditions. Verify compatibility with the intended switching frequency spectrum. Compare alternative ratios if different scaling factors are necessary for the measurement circuit.

Part Context

This part belongs to the ECSTA1V1308 series of current sense transformers. The series offers various turns ratios to accommodate different current levels. The 1040 suffix specifically denotes the 40:1 configuration. These components are engineered for surface mount technology to facilitate automated assembly processes.

Replacement Considerations

Direct substitutes include other variants within the ECSTA1V1308 family, such as the ECSTA1V1308-1050-R, which provides a 50:1 ratio. Ensure any replacement maintains the same physical footprint and electrical parameters relevant to the specific application design.
