• Through-hole mounting configuration for PCB integration
• High inductance value supporting stable signal transformation

Current Sense Transformers Applications

• Current monitoring in power supply circuits
• Feedback control systems requiring isolated current measurement
• Protection circuits detecting overcurrent conditions

Current Sense Transformers Procurement Notes

Verify the specific datasheet version from Amgis, LLC to confirm electrical tolerances and thermal characteristics. Ensure the through-hole footprint matches the specified dimensions of 17.20mm x 9.53mm during PCB layout. Confirm that the operating frequency range of 20kHz to 200kHz aligns with the target application's switching speed to maintain accurate current sensing performance.

Current Sense Transformers Selection Notes

Select this component when non-invasive current measurement is required without breaking the primary circuit. The 1:200 ratio suits applications where secondary side amplification is available. Verify that the 2.25 Ohm maximum resistance does not introduce excessive voltage drop in the primary conductor. Ensure the 20kHz lower frequency limit meets the minimum operational frequency of the system.
