T10135A-50HF

Overview

The T10135A-50HF is a surface mount current sense transformer manufactured by ITG Electronics, Inc. It features a turns ratio of 1:50 and supports a maximum primary current of 80 A. The device has a primary resistance of 0.08 mOhm and a maximum secondary resistance of 900 mOhm. Its inductance is specified at 1.5 mH.

Feature Summary

• Surface mount construction for automated assembly
• High current sensing capability up to 80 A
• Fixed 1:50 transformation ratio

Applications

• Current monitoring in power supply circuits
• Overcurrent protection systems
• Feedback loops in switching regulators

Procurement Notes

Verify the specific suffix HF against the manufacturer's latest documentation to confirm compliance with hazardous substance restrictions. Ensure the ordering part number matches the required 1:50 ratio and 1.5 mH inductance specifications exactly. Cross-reference the datasheet revision date to validate electrical parameters before finalizing procurement orders.

Selection Notes

Select this component when a fixed 1:50 ratio is required for high-current applications up to 80 A. The low primary resistance minimizes insertion loss. Verify that the 900 mOhm maximum secondary resistance fits within the burden resistor design constraints. Confirm surface mount footprint compatibility with the target PCB layout.

Part Context

This part belongs to the T10135 series of current sense transformers from ITG Electronics. The series offers various ratios and inductance values tailored for different current levels. The T10135A variant specifically addresses higher current requirements compared to lower-rated siblings in the same product family.

Replacement Considerations

Direct substitutes include other T10135A models with identical 1:50 ratios, such as those with different inductance tolerances if compatible. Verify pinout and mechanical dimensions match before replacing.
