CSE5-101001

Overview

The Triad Magnetics CSE5-101001 is a surface-mount current sense transformer designed for high-frequency applications. It features a 1:100 turns ratio and a primary current rating of 10 A. The secondary inductance is 2 mH with a maximum DC resistance of 5.5 ohms. Operating up to 250 kHz, it provides electrical isolation for precise current monitoring. The component measures 7.7 mm in length, 6.9 mm in width, and 5.33 mm in height.

Feature Summary

• Provides galvanic isolation between primary circuit and sensing electronics
• Designed for high-frequency operation up to 250 kHz
• Surface-mount construction for automated PCB assembly

Applications

• Switch-mode power supply current monitoring
• Inverter and motor drive protection circuits
• High-frequency AC current measurement systems

Procurement Notes

Verify the specific suffix against official Triad Magnetics documentation to confirm exact electrical tolerances and packaging configuration. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Confirm that the operating frequency range aligns with the 250 kHz specification before finalizing orders.

Selection Notes

Select this component when invasive current sensing with galvanic isolation is required in compact designs. The 1:100 ratio suits applications needing signal scaling for low-voltage ADC inputs. Verify that the 10 A primary rating meets peak load requirements and that the 5.5 ohm secondary resistance fits the burden resistor design constraints.

Part Context

This part belongs to the CSE5 series of high-frequency current sense transformers manufactured by Triad Magnetics. The series utilizes surface-mount technology to facilitate integration into modern electronic assemblies. These components are engineered to provide reliable performance in demanding power conversion environments requiring accurate current feedback.

Replacement Considerations

Consult official manufacturer substitution guides for verified equivalents. Cross-referencing requires matching the 1:100 ratio, 2 mH inductance, and 10 A current rating. Physical footprint compatibility must be confirmed if replacing on existing PCB layouts.
