Overview
The T10135C-500HF is a surface-mount current sense transformer manufactured by ITG Electronics, Inc. It features a primary-to-secondary turns ratio of 1:500 and supports a maximum primary current of 50 A. The component exhibits a primary resistance of 0.28 mOhm and a secondary resistance of up to 66 Ohm. Its magnetizing inductance is rated at a maximum of 155 mH. This device is designed for precise current monitoring applications requiring high isolation and accurate signal transformation in compact electronic systems.
Feature Summary
- Provides electrical isolation between primary and secondary circuits via transformer coupling
- Delivers accurate current sensing through a fixed 1:500 turns ratio
- Optimized for surface-mount technology integration into printed circuit boards
Applications
- Current monitoring in power supply units
- Overcurrent protection circuits in industrial electronics
- Feedback control loops in switching regulators
Procurement Notes
Verify the manufacturer part number T10135C-500HF against official ITG Electronics documentation to confirm specifications. Ensure compatibility with surface-mount assembly processes. Check for RoHS compliance status if required by project standards. Confirm that the 50 A rating and 155 mH inductance meet design requirements before procurement.
Selection Notes
Select this component when a 1:500 ratio and 50 A primary current capacity are required. Consider the 0.28 mOhm primary resistance for loss calculations. Verify that the 155 mH maximum inductance suits the operating frequency. Ensure the surface-mount package fits the PCB layout constraints. Compare against other T10135 series variants if different ratios or current ratings are needed.
Part Context
This part belongs to the T10135 series of current sense transformers from ITG Electronics. The series offers various configurations with different turns ratios and current ratings. The T10135C-500HF specifically targets high-current applications with a 50 A rating. It complements other models like the T10135B-200HF which offer lower current capacities.
Replacement Considerations
Direct substitutes within the same series include the T10135C-600HF, which shares similar characteristics but may differ in specific parameters. Verify exact electrical equivalence before substitution. No alternative part numbers are confirmed as direct replacements in available public data.
