CSE5-100501

Overview

The Triad Magnetics CSE5-100501 is a surface-mount current sense transformer designed for high-frequency applications. It features a 1:50 turns ratio and operates optimally at frequencies of 250 kHz and above. The component has a primary current rating of 10,000 mA (10 A) and a maximum secondary DC resistance of 1.5 Ohms. It utilizes an EE5 bobbin design with gull-wing SMD terminals for vertical welding. Physical dimensions are approximately 6.90 mm in length and 7.70 mm in width, with a height of 5.3 mm.

Feature Summary

• Optimized performance for switching frequencies of 250 kHz and higher
• Surface-mount construction with gull-wing terminals for automated assembly
• High primary current handling capability up to 10 A
• Compact EE5 core geometry suitable for dense PCB layouts

Applications

• Current sensing in high-frequency switch-mode power supplies
• Over-current protection circuits in industrial electronics
• Feedback loops in isolated converter topologies
• Battery management systems requiring precise current monitoring

Procurement Notes

Verify the specific package variant and terminal configuration upon ordering, as surface-mount components may have distinct footprint requirements. Confirm that the selected supplier provides genuine Triad Magnetics products to ensure adherence to the specified electrical characteristics and thermal limits. Check for any recent manufacturing updates or pinout revisions in the latest datasheet before finalizing the bill of materials.

Selection Notes

Select this component when a compact, surface-mount solution is required for currents exceeding standard signal levels. Ensure the operating frequency of the target circuit remains at or above 250 kHz to maintain accuracy. Evaluate the thermal environment, as the small form factor may limit heat dissipation compared to through-hole alternatives under continuous high-load conditions.

Part Context

This part belongs to Triad Magnetics' line of current sense transformers, which are engineered for precision measurement in power electronics. The CSE5 series specifically targets applications demanding low profile and reliable performance in space-constrained designs. These components serve as critical interfaces between high-power stages and control logic.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacements require matching the 1:50 ratio, 250 kHz minimum frequency, and compatible SMD footprint.
