749196131

Overview

The Würth Elektronik 749196131 is a WE-FLEX flexible transformer designed for DC/DC converter applications. It features a pulse transformer configuration with an inductance of 10.9 µH and a turns ratio of 1:1:1:1:1:1. The component provides 500 VAC isolation voltage and supports a maximum current of 550 mA. It utilizes surface mount technology for board integration, ensuring reliable performance in general electronic equipment environments while meeting REACH and RoHS standards.

Feature Summary

• Flexible construction allows for compact design integration in space-constrained applications
• High isolation voltage capability ensures safety in power conversion circuits
• Multi-winding configuration supports complex signal or power distribution requirements

Applications

• DC/DC converter modules
• General electronic equipment power supplies
• Isolated power stage implementations

Procurement Notes

Verify the specific datasheet version to confirm pinout compatibility and thermal limits before integration. Ensure that the operating temperature range aligns with your system's environmental conditions. Cross-reference the isolation voltage rating with your safety certification requirements. Confirm that the surface mount footprint matches your PCB layout constraints. Validate that the 550 mA current rating meets the peak load demands of your application circuit.

Selection Notes

Choose this component when flexible form factors are required for custom winding arrangements or tight spatial restrictions. The 1:1:1:1:1:1 ratio suits applications needing multiple isolated outputs or complex feedback paths. Consider the 500 VAC isolation if high voltage separation is critical. Evaluate the 10.9 µH inductance against your switching frequency requirements to ensure efficient energy transfer without saturation issues in the target DC/DC topology.

Part Context

This part belongs to the WE-FLEX series, which specializes in flexible transformers for customized power solutions. Unlike rigid core transformers, these components offer adaptability for unique mechanical layouts. The series targets designers requiring bespoke electromagnetic characteristics within standard surface mount processes, bridging the gap between off-the-shelf availability and custom coil windings.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 10.9 µH inductance, 1:1:1:1:1:1 ratio, and 500 VAC isolation. Verify that any alternative component maintains the same flexible package dimensions and surface mount compatibility to avoid PCB redesign.
