ECST1V1308-1070-R

Overview

The ECST1V1308-1070-R is a board-mount current transformer from Eaton Electronics, designed for surface mount technology (SMD) applications. It features a primary current rating of 15 A and a turns ratio of 70:1. The component exhibits an inductance of 2.7 uH and a secondary resistance of 1 Ohm. It operates within a frequency range of 50 kHz to 1 MHz. The physical dimensions are 13 mm in length, 11 mm in width, and 7.8 mm in height. The device supports an operating temperature range from -40 C to +125 C.

Feature Summary

• Surface mount design for automated PCB assembly
• High-frequency operation capability up to 1 MHz
• Compact form factor suitable for space-constrained layouts

Applications

• Current sensing in high-frequency power supplies
• Overcurrent protection circuits
• Active PFC stage monitoring

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when placing orders. Confirm that the 70:1 ratio matches the target signal conditioning requirements. Ensure soldering procedures adhere to thermal limits, as manual hand soldering is generally not recommended. Check for RoHS compliance status prior to final procurement approval.

Selection Notes

Select this component when a 15 A primary rating and 70:1 step-down ratio are required. The 2.7 uH inductance must align with the intended load impedance. Verify that the 50 kHz to 1 MHz bandwidth covers the switching frequencies of the application. The SMD package type dictates the footprint constraints on the printed circuit board.

Part Context

This part belongs to the ECST series of current sense transformers manufactured by Eaton Electronics. These components are engineered for invasive current measurement in electronic circuits. The series provides various turns ratios to suit different sensing needs while maintaining consistent physical and electrical characteristics across the family.

Replacement Considerations

Consult official Eaton documentation for direct substitutes. Other models in the ECST1V1308 series may offer different turns ratios, such as 60:1 or 120:1, but require verification of electrical compatibility before substitution.
