ECST1V0504-1100-R

Overview

The ECST1V0504-1100-R is a surface-mount current sense transformer from Eaton Electronics. It features a 7 A primary current rating and a 100:1 turns ratio. The component provides an inductance of up to 820 µH with a maximum primary DC resistance of 3 mΩ and a secondary DC resistance of 9.5 Ω. Designed for high-frequency applications, it operates within a frequency range of 50 kHz to 1 MHz.

Feature Summary

• Provides precise current sensing through a fixed 100:1 step-down turns ratio.
• Features low primary DC resistance to minimize insertion loss in the circuit.
• Engineered for surface-mount technology (SMT) integration on PCBs.

Applications

• High-frequency power supply current monitoring
• Motor drive control systems
• DC-DC converter feedback loops

Procurement Notes

Verify the specific manufacturer part number against official Eaton documentation to confirm electrical parameters. Ensure the selected variant matches the required turns ratio and current rating for the target application. Cross-reference datasheet specifications regarding thermal limits and soldering profiles before implementation.

Selection Notes

Select this component when a compact SMT solution is required for high-frequency current sensing. The 100:1 ratio suits applications needing significant signal attenuation. Verify that the 7 A primary rating and 820 µH inductance meet the system's bandwidth and saturation requirements.

Part Context

This model belongs to the ECST series of current sense transformers by Eaton Electronics. These components are designed for board-level mounting and offer various turn ratios. The series supports applications requiring isolated current measurement in switching power electronics environments.

Replacement Considerations

Direct substitutes must match the 7 A rating, 100:1 ratio, and SMD footprint. Consult Eaton's official cross-reference tools or distributor databases for verified equivalent part numbers with identical electrical characteristics.
