AS-105 is listed in the Current Sense Transformers range at ChipApex. The manufacturer field lists Amgis, LLC. Its product description is CURR SENSE XFMR 30A 1:750 VRT. Review the specifications below when checking this part for your BOM.
The AS-105 is a current sense transformer manufactured by Amgis, LLC. It features a turns ratio of 1:750 and is rated for a primary current of 30A. The component provides an isolation voltage rating of 3750V·us. This device is designed for accurate current monitoring applications requiring galvanic isolation between the high-current primary circuit and the low-current secondary sensing circuit.
Verify the specific datasheet version when ordering, as manufacturing specifications may vary. Confirm that the 1:750 ratio and 30A rating align with your system requirements. Check lead times, which are reported at approximately 13 weeks from the manufacturer. Ensure compatibility with your PCB footprint and secondary winding configuration before finalizing procurement.
Select this component when a high isolation voltage and specific 1:750 transformation ratio are required. The 30A primary rating suits medium-to-high current applications. Consider the physical size and mounting style if space is constrained. Verify that the secondary inductance characteristics meet the bandwidth needs of your control loop or sensing interface.
Amgis, LLC specializes in magnetic components including transformers and inductors. The AS-105 belongs to their current sense transformer series, designed for industrial and commercial power electronics. These components emphasize reliability and electrical isolation to protect sensitive control circuitry from high-voltage faults in the primary power path.
No public confirmed substitute part numbers are available in the provided documentation. When replacing, ensure the new component matches the 1:750 ratio, 30A current rating, and 3750V·us isolation specification. Physical dimensions and pinout compatibility must also be verified.
