Overview

The Würth Elektronik 749196520 is a surface-mount power transformer from the WE-FLEX series, designed for flexible DC/DC switching converter applications. It features an inductance of 5.3 µH at 10 kHz and supports a maximum current of 2.53 A (rated) or 1.91 A (alternative rating). The component provides 500 VDC isolation voltage and utilizes an air gap core design. Operating within a temperature range of -40°C to +125°C, it is suitable for high-frequency operations up to 400 kHz.

Feature Summary

Flexible configuration capability for configurable DC/DC converters
Integrated air gap core structure for stable magnetic performance
High isolation voltage rating ensuring safety in power circuits

Applications

Configurable DC/DC power supply modules
Industrial switching mode power supplies
Telecommunications infrastructure power systems

Procurement Notes

Verify the specific datasheet revision and electrical ratings against your design requirements, as manufacturer documentation may list varying current parameters (e.g., 2.53 A vs. 1.91 A). Confirm that the surface-mount package dimensions and pinout match your PCB footprint. Ensure the operating frequency range aligns with your converter's switching speed to maintain efficiency and thermal stability.

Selection Notes

Select this component when designing isolated DC/DC converters requiring flexible winding configurations and robust isolation. The WE-FLEX series offers adaptability for various voltage conversion needs. Consider the 500 VDC isolation barrier and wide temperature tolerance for demanding environments. Evaluate the 5.3 µH inductance value against your specific ripple current and regulation requirements.

Part Context

This part belongs to Würth Elektronik’s WE-FLEX family of transformers, which are engineered for versatility in power electronics. Unlike fixed-ratio transformers, these components support customizable designs for non-standard voltage conversions. They are widely used in industrial and communication sectors where reliable isolation and compact form factors are critical for system integration.
