• Provides galvanic isolation between primary and secondary circuits for accurate current monitoring.
• Optimized for high-frequency operation up to 1 MHz with low primary impedance.
• Compact surface-mount footprint facilitates automated assembly and space-constrained designs.

Current Sense Transformers Applications

• Current sensing in switch-mode power supplies
• Overcurrent protection circuits in industrial equipment
• Feedback loops in isolated power converters

Current Sense Transformers Procurement Notes

Verify the specific manufacturer part number against official Pulse Electronics documentation to ensure compatibility with design requirements. Confirm that the 1:30 turns ratio and 180 µH inductance align with the target application's signal processing needs. Check for RoHS compliance status and moisture sensitivity level classifications prior to ordering. Ensure storage conditions adhere to the specified limits to maintain component integrity during handling.

Current Sense Transformers Selection Notes

Select this component when a compact, high-isolation current transformer is required for frequencies above 50 kHz. The 1:30 ratio suits applications needing significant signal transformation for sensing purposes. Consider the 6 mΩ primary resistance for minimal insertion loss in high-current paths. Evaluate the 5.50 mm height constraint against available board clearance. Compare against other series members if different ratios or inductance values are necessary.
