CSE5-100701

Overview

The Triad Magnetics CSE5-100701 is a high-frequency current sense transformer designed for surface-mount applications. It features a turns ratio of 1:70 and a minimum inductance of 980 µH. The secondary DC resistance is specified at a maximum of 4.75 ohms, while the primary current rating reaches 20,000 mA. This component utilizes a gull-wing SMD package with six terminals to facilitate precise electrical monitoring in compact circuit designs.

Feature Summary

• Surface-mount construction with gull-wing terminals for automated assembly
• High turns ratio for accurate current sensing and isolation
• Optimized for high-frequency operation within power electronics

Applications

• Switch-mode power supply current monitoring
• Industrial motor drive protection circuits
• Battery management system current measurement

Procurement Notes

Verify the specific datasheet revision when sourcing to ensure compatibility with latest manufacturing standards. Confirm that the supplier provides original manufacturer documentation rather than third-party summaries. Check for any regional compliance certifications required for your target market before finalizing orders.

Selection Notes

Select this component when a high turns ratio and low secondary resistance are critical for signal integrity. Ensure the PCB layout supports the six-terminal gull-wing footprint. Evaluate thermal constraints as the device handles significant primary currents during peak load conditions.
