Overview
The ECST1V0504-1060-R is a surface-mount current sense transformer from Eaton Electronics, designed for board-level integration. It features a turns ratio of 1:60 and supports a primary current rating of 7 A. The component exhibits an inductance of 295 uH with a secondary resistance of 3.6 Ohms. It operates within a frequency range of 50 kHz to 1 MHz. Physical dimensions are 4.8 mm in length, 3.65 mm in width, and 3.65 mm in height. The device functions reliably between -40 C and +125 C.
Feature Summary
- Surface-mount construction for automated PCB assembly
- High-frequency operation capability up to 1 MHz
- Compact footprint suitable for space-constrained designs
Applications
- Current sensing in switching power supplies
- Overcurrent protection circuits
- Feedback control loops in DC-DC converters
Procurement Notes
Verify the specific suffix against official Eaton documentation to confirm electrical tolerances and packaging options. Ensure the procurement channel provides valid traceability for industrial applications. Confirm that the delivered units match the exact part number designation to avoid compatibility issues with existing circuit designs.
Selection Notes
Select this component when a 1:60 ratio and 7 A primary rating align with system requirements. Evaluate the 295 uH inductance against the target switching frequency to ensure accurate signal fidelity. Consider the 3.6 Ohm secondary resistance impact on downstream amplifier loading before finalizing the design.
Part Context
This model belongs to the ECST series of current sense transformers manufactured by Eaton Electronics. These components are engineered for high-reliability electronic systems requiring precise current monitoring. The series offers various ratios and ratings to accommodate different power management architectures.
Replacement Considerations
Cross-reference with ECST1V0504-1050-R for a 50:1 ratio variant or ECST1V0504-1125-R for different resistance characteristics. Verify that substitute parts maintain compatible physical dimensions and thermal performance specifications.
