749196148

Overview

The Würth Elektronik 749196148 is a flexible surface-mount transformer from the WE-FLEX HV series, designed for DC/DC converters and SMPS applications. It features 1500Vrms isolation voltage and an inductance of 8.5µH at 100kHz. The component operates within a temperature range of -40°C to 125°C. Its dimensions are 13.00mm x 12.90mm with a maximum height of 6.20mm. It is supplied in tape and reel packaging.

Feature Summary

• Flexible construction suitable for compact or irregular PCB layouts
• High voltage isolation capability for safety-critical circuits
• Surface mount design for automated assembly processes

Applications

• DC/DC converter modules
• Switched-mode power supplies (SMPS)
• Isolated power conversion stages

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status before integration. Confirm that the flexible form factor meets mechanical stress requirements in the final assembly. Ensure the 1500Vrms isolation rating aligns with system safety standards. Check for any recent production changes via PCN documentation.

Selection Notes

Select this component when high isolation voltage is required in a small footprint. The flexible body allows for placement in tight spaces where rigid transformers cannot fit. Consider the operating temperature range of -40°C to 125°C for harsh environments. Verify compatibility with the target DC/DC converter topology.
