AS-102

Current Sense Transformers Overview

The AS-102 is a toroidal current sense transformer manufactured by Amgis, LLC. It features a non-invasive solid core design suitable for through-hole mounting. The component operates at standard power frequencies of 50/60Hz and has a maximum DC resistance (DCR) of 600mOhm on the secondary winding. Physical dimensions are 0.677 inches in length and 0.375 inches in width, corresponding to 17.20mm x 9.53mm. The unit weighs approximately 0.04 ounces.

Current Sense Transformers Feature Summary

• Non-invasive solid core construction for direct wire insertion
• Through-hole mounting configuration for PCB integration
• Optimized for 50/60Hz AC current sensing applications

Current Sense Transformers Applications

• AC current monitoring in power supplies
• Current feedback loops in industrial inverters
• Energy metering systems requiring galvanic isolation

Current Sense Transformers Procurement Notes

Verify the specific secondary turns ratio and inductance requirements against application datasheets, as these parameters vary within the AS series. Confirm that the 600mOhm DCR limit aligns with signal conditioning circuit input impedance. Ensure the through-hole footprint matches the 17.20mm x 9.53mm physical envelope during PCB layout finalization.

Current Sense Transformers Selection Notes

Select this component when a low-profile, non-invasive solution is required for 50/60Hz current measurement. The small form factor suits space-constrained designs. Verify that the operating frequency range strictly covers the target 50/60Hz spectrum, as performance may differ at higher frequencies. Check that the mechanical height fits within the assembly clearance limits.

Current Sense Transformers Part Context

The AS-102 belongs to the Amgis toroidal current transformer family, which emphasizes compact magnetic components for power electronics. This series provides galvanic isolation between primary conductors and secondary sensing circuits. The manufacturer specializes in high-frequency and power magnetic components, positioning this part as a standard solution for basic AC current detection tasks.

Current Sense Transformers Replacement Considerations

Cross-reference with other Amgis models such as CT-1040 or AS-310 if different current ratios or physical sizes are needed. Ensure substitute parts maintain the same through-hole mounting style and toroidal geometry to preserve existing PCB footprints and assembly processes.
