750316793

Current Sense Transformers Overview

The Würth Elektronik 750316793 is a surface-mount current sense transformer designed for high-frequency power management applications. It features a 1:50 turns ratio and an inductance of 1400 uH (1.4 mH). The device supports a frequency range from 50 kHz to 500 kHz and handles primary currents up to 40 A. With a maximum operating temperature of +125°C and a minimum of -40°C, it ensures reliable performance across industrial environments. The component has a DCR of 280 mOhm and measures 10.5 mm in height.

Current Sense Transformers Feature Summary

• Provides galvanic isolation between the primary current path and the secondary sensing circuitry.
• Optimized for high-frequency operation within the 50 kHz to 500 kHz range.
• Designed for direct surface-mount installation on printed circuit boards.

Current Sense Transformers Applications

• Current monitoring in switching mode power supplies (SMPS)
• Overcurrent protection circuits in industrial power systems
• Feedback loop sensing in isolated DC-DC converters

Current Sense Transformers Procurement Notes

Verify the specific datasheet revision and RoHS compliance status prior to ordering, as manufacturing updates may occur. Confirm that the 40 A current rating aligns with the peak requirements of the target application circuit. Ensure the PCB footprint matches the mechanical dimensions provided in the official package drawing to avoid assembly errors during production.

Current Sense Transformers Selection Notes

Select this component when a high-current, high-frequency solution is required for isolated current sensing. The 1:50 ratio suits applications needing precise signal scaling for downstream ADC or comparator inputs. Consider the 1400 uH inductance value to ensure adequate magnetizing inductance at the lowest operating frequency of 50 kHz to prevent saturation.
