Overview
The ECST1V0805-1070-R is a surface-mount current sense transformer from Eaton Electronics, designed for high-frequency applications. It features a primary rated current of 10 A and a turns ratio of 70:1. The component operates within a frequency range of 50 kHz to 1 MHz and has an inductance of 80 uH. Physical dimensions are 8.38 mm in length, 8 mm in width, and 5.5 mm in height. It supports SMD/SMT installation and functions between -40 C and +125 C.
Feature Summary
- Surface-mount design with EE5.0 package format
- Wide turns ratio selection capability
- Low DC resistance characteristics
- Operation up to 1 MHz frequency
Applications
- Current sensing in power supply circuits
- High-frequency signal monitoring
- SMD-based electronic assemblies
Procurement Notes
Verify the specific part number against official Eaton documentation to confirm the 70:1 turns ratio and 10 A rating. Ensure compatibility with SMD/SMT assembly processes and check temperature ratings for operational environments. Confirm RoHS compliance status through manufacturer datasheets before integration.
Selection Notes
Select this component when a 70:1 transformation ratio is required for current sensing at frequencies up to 1 MHz. Consider the 10 A primary current limit and physical footprint constraints. Evaluate thermal performance within the specified operating temperature range and ensure PCB layout supports surface-mount soldering requirements.
Part Context
This model belongs to the ECST series of current transformers by Eaton Electronics. These components are engineered for board-mounted applications requiring precise current measurement. The series offers various turns ratios to suit different circuit designs while maintaining consistent physical dimensions and mounting styles.
Replacement Considerations
ECST1V0805-1030-R and ECST1V0805-1070-R are related models within the same series. Verify turns ratio differences (30:1 vs 70:1) and electrical parameters when substituting. Ensure interface and mechanical compatibility remain unchanged.
