Overview
The T10135B-400HF is a surface-mount current sense transformer manufactured by ITG Electronics, Inc. It features a turns ratio of 1:400 and supports a primary current rating of 60 A. The component has a primary resistance of 0.18 mOhm and a secondary resistance of 50 Ohm. The maximum inductance is specified as 100 mH.
Feature Summary
- Surface mount construction for automated assembly
- High isolation current sensing capability
- Defined primary and secondary impedance characteristics
Applications
- Switch mode power supply current monitoring
- Overcurrent protection circuits
- Power management system feedback loops
Procurement Notes
Verify the specific suffix HF indicates RoHS compliance status with the manufacturer. Confirm the package dimensions match the PCB footprint requirements. Ensure the 60 A primary current rating aligns with the peak load conditions of the target application circuit to prevent saturation or thermal issues during operation.
Selection Notes
Select this component when a high turns ratio of 1:400 is required for precise low-current secondary signal generation from a 60 A primary line. Consider the 0.18 mOhm primary resistance for minimal voltage drop impact. Evaluate the 50 Ohm secondary impedance against the input impedance of the downstream sensing amplifier or ADC interface to ensure proper signal transfer and loading conditions.
Part Context
This part belongs to the T10135 series of current sense transformers from ITG Electronics. The series offers various ratios and current ratings. The T10135B-400HF specifically targets applications requiring high isolation and accurate current replication at a 1:400 ratio within a compact surface-mount form factor suitable for modern power electronics designs.
Replacement Considerations
Direct substitutes include other models from the T10135 series such as T10135A-400HF or T10135C-400HF if available, provided they meet the same 1:400 ratio and 60 A rating constraints. Verify pin compatibility and electrical parameters before substitution.
