Overview
The Würth Elektronik 749196141 is a flexible SMPS transformer from the WE-FLEX series, designed for DC/DC converters. It features an inductance of 8.5µH at 10kHz and supports a current rating of 550mA. The component provides 500Vrms isolation voltage and operates within a temperature range of -40°C to +125°C. Its surface-mount package measures 12.90mm x 9.20mm with a maximum height of 6.20mm. The unit complies with RoHS3 standards and has a moisture sensitivity level of 1.
Feature Summary
- Flexible construction suitable for custom winding configurations
- High isolation voltage for safety compliance
- Surface mount design for automated assembly
Applications
- DC/DC converter circuits
- SMPS transformer applications
- Custom power supply designs requiring flexible windings
Procurement Notes
Verify the specific pinout and winding configuration against the official datasheet before integration, as flexible transformers may require custom termination. Confirm that the 500Vrms isolation rating meets system safety requirements. Ensure PCB footprint matches the 12.90mm x 9.20mm dimensions. Check RoHS3 compliance documentation if required by project specifications.
Selection Notes
Select this component when a standard transformer does not fit the mechanical constraints or requires non-standard turns ratios. The flexible core allows for custom winding to achieve specific electrical characteristics. Consider the 8.5µH inductance and 550mA current limit for circuit compatibility. The wide operating temperature range supports harsh environments.
Part Context
This part belongs to the Würth Elektronik WE-FLEX series, which specializes in flexible transformers for customized power electronics. Unlike fixed-winding transformers, these components allow engineers to define primary and secondary turns to meet unique voltage and impedance requirements in DC/DC conversion topologies.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific flexible configuration. Custom winding requirements typically necessitate designing a new solution rather than swapping to a standard off-the-shelf equivalent.
