AS-113

Current Sense Transformers Overview

The AS-113 is a current sense transformer manufactured by Amgis, LLC, designed for through-hole mounting. It features a turns ratio of 1:300CT and supports a maximum primary current of 15A. The component operates within a frequency range of 20kHz to 200kHz. Key electrical specifications include a maximum secondary resistance of 5 Ohms and a secondary inductance of 250 mH. These parameters define its performance characteristics for signal isolation and measurement applications.

Current Sense Transformers Feature Summary

• Provides galvanic isolation between primary and secondary circuits via electromagnetic induction
• Designed for high-frequency operation suitable for switching power supply environments
• Through-hole construction facilitates integration into printed circuit board assemblies

Current Sense Transformers Applications

• Current sensing in switch-mode power supplies
• Isolated feedback loops in DC-DC converters
• Overcurrent protection circuits requiring precise signal transfer

Current Sense Transformers Procurement Notes

Verify the specific manufacturing date code and lot number upon receipt to ensure compliance with project requirements. Confirm that the received components match the specified 1:300CT ratio and 15A rating. Inspect leads for damage and ensure the package integrity remains intact during handling and storage to maintain operational reliability.

Current Sense Transformers Selection Notes

Select this component when isolated current monitoring is required at frequencies above 20kHz. Ensure the primary current does not exceed 15A to prevent saturation. Verify that the PCB layout accommodates the through-hole footprint and that the secondary load impedance is compatible with the 5 Ohm maximum resistance specification for accurate signal transmission.

Current Sense Transformers Part Context

The AS-113 belongs to the AS series of current sense transformers from Amgis, LLC. This series focuses on providing reliable magnetic coupling for power electronics applications. The model utilizes toroidal core technology to minimize electromagnetic interference and leakage inductance, distinguishing it from standard planar transformers in terms of noise performance and efficiency.
