T10135A-100HF

Overview

The T10135A-100HF is a surface mount current sense transformer manufactured by ITG Electronics, Inc. It features a primary resistance of 0.08mOhm and a maximum secondary resistance of 2.5 Ohm. The device has a turns ratio of 1:100 and a maximum inductance of 6 mH. It is rated for a primary current of 80 A.

Feature Summary

• Surface mount construction for automated assembly
• High current sensing capability up to 80 A
• Defined 1:100 turns ratio for signal isolation

Applications

• Current monitoring in power supply circuits
• Overcurrent protection systems
• Isolated current feedback loops

Procurement Notes

Verify the specific suffix HF against the manufacturer's latest datasheet to confirm RoHS compliance status and lead times. Ensure the ordering part number matches the required inductance tolerance and physical dimensions for your PCB layout. Cross-reference with ITG Electronics official documentation to validate availability and any recent design changes.

Selection Notes

Select this component when an 80 A primary current rating and a 1:100 transformation ratio are required. The 0.08mOhm primary resistance minimizes insertion loss. Verify that the 6 mH maximum inductance meets the frequency response requirements of the application circuit. Ensure the surface mount package fits the designated footprint.

Part Context

This part belongs to the T10135 series of SMD current sense transformers from ITG Electronics. The series offers various turn ratios and inductance values while maintaining consistent primary resistance characteristics. It is designed for high-current applications requiring galvanic isolation between the primary conductor and the sensing electronics.

Replacement Considerations

Direct substitutes include other models within the T10135A series with similar ratios, such as the T10135A-60HF or T10135A-200HF, provided the specific inductance and resistance parameters align with the circuit design requirements.
