750319331

Overview

The Würth Elektronik 750319331 is a WE-AGDT auxiliary gate drive transformer designed for high-frequency applications. It features a 1:1 turns ratio and an inductance of 50µH with a DC resistance of 0.085Ω. The component provides 4kV isolation voltage and operates within a temperature range of -40°C to +130°C. It utilizes a surface mount package measuring 11.30mm x 10.95mm, suitable for compact PCB layouts.

Feature Summary

• Provides galvanic isolation between control circuitry and power devices
• Optimized for auxiliary gate drive signal transmission
• Supports high operating temperatures up to 130°C

Applications

• DC/DC converter gate driving
• Auxiliary winding excitation
• High-frequency isolated signal coupling

Procurement Notes

Verify the specific datasheet version and marking code (319331) upon receipt. Confirm that the surface mount footprint matches the design requirements. Ensure storage conditions remain below 40°C and 75% RH prior to use to maintain component integrity.

Selection Notes

Select this component when a 1:1 isolated gate drive transformer is required for auxiliary functions. The 50µH inductance and 4kV isolation are key differentiators. Consider the 11.30mm x 10.95mm SMD package dimensions for board space constraints.
