ECSTA1V0805-1060-R

Overview

The ECSTA1V0805-1060-R is a surface-mount current sense transformer from Eaton Electronics, designed for board-level integration. It features a 1:60 turns ratio and supports primary currents up to 10 A. The component operates within a frequency range of 50 kHz to 1 MHz, with a maximum inductance of 730 µH. Electrical characteristics include a primary resistance of 0.7 mΩ and a secondary resistance of 2.3 Ω. It utilizes SMD/SMT mounting styles and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Surface-mount design optimized for automated PCB assembly processes
• High-frequency operation capability suitable for switching power applications
• Robust thermal performance supporting extreme ambient conditions

Applications

• Current sensing in DC-DC converter circuits
• Overcurrent protection mechanisms in power supplies
• Feedback control loops in battery management systems

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging configuration as per manufacturer documentation. Confirm that the 10 A rating aligns with your peak load requirements rather than continuous average current alone. Ensure compatibility with standard reflow soldering profiles specified in the datasheet to maintain component integrity during assembly.

Selection Notes

Select this model when a 1:60 ratio provides optimal signal scaling for your ADC or comparator input. Consider the low primary inductance for high-speed transient response needs. Evaluate the physical footprint against available PCB real estate, noting the compact dimensions relative to through-hole alternatives. Verify that the secondary burden resistor matches the impedance specifications for accurate current measurement.
