Current Sense Transformers Overview

The SCS-8-3-80T-TR is a surface-mount current sense transformer from the SCS8.3 series, manufactured by Signal Transformer. It features a current ratio of 80:1 and operates within a frequency range of 50kHz to 1MHz. The device has a maximum primary resistance of 3.9mOhm and a secondary resistance of 1.3Ohm. Its inductance is specified at 3.5mH. Designed for board mounting, it supports a maximum current of 15A and utilizes gull-wing termination style.

Current Sense Transformers Feature Summary

• Surface mount design for automated assembly
• High-frequency operation capability up to 1MHz
• Shielded construction to minimize electromagnetic interference

Current Sense Transformers Applications

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

Current Sense Transformers Procurement Notes

Verify the specific manufacturer designation, as sources reference both Bel Signal Transformer and Signal Transformer. Confirm the exact datasheet version matches the 3.5mH inductance and 80:1 ratio specifications. Ensure the reel packaging format aligns with production requirements. Cross-reference the 15A rating against thermal constraints in the final application environment.

Current Sense Transformers Selection Notes

Select this component when high-frequency current sensing between 50kHz and 1MHz is required. The 80:1 ratio suits applications needing significant signal attenuation. The low primary resistance minimizes insertion loss. Verify that the 15A maximum current rating exceeds peak operational loads. Consider the surface-mount footprint compatibility with PCB layout constraints.

Current Sense Transformers Part Context

This part belongs to the SCS8.3 series of high-frequency current-sensing transformers. These devices are designed for surface-mount technology, offering compact solutions for modern electronics. The series provides various ratios and inductance values to accommodate different circuit requirements while maintaining consistent performance characteristics across the family.

Current Sense Transformers Replacement Considerations

The SCS-8-3-40T-TR and SCS-8-3-125T-TR are related parts within the same series. Substitution requires verifying that the alternative ratio (40:1 or 125:1) meets the system's sensing needs. Ensure the replacement maintains the 50kHz-1MHz frequency range and compatible physical dimensions.
