It belongs to the WE-PP, MID-PPTI series and supports forward and push-pull converter topologies. The component features 5000Vrms isolation voltage and operates at a frequency of 150kHz. Inductance is specified as 440µH at 100kHz. Physical dimensions are 12.32mm x 15.41mm with a maximum height of 11.18mm. It is rated for an operating temperature range of -40°C to 125°C.
Feature Summary
- Provides high-voltage isolation suitable for safety-critical power conversion circuits
- Optimized magnetic design for forward and push-pull converter topologies
- Compact surface-mount form factor facilitates automated PCB assembly
Applications
- Forward converter DC/DC power supplies
- Push-pull converter DC/DC power supplies
- Switching Mode Power Supply (SMPS) units
Procurement Notes
Verify the specific inductance value required by your circuit design against the datasheet specification of 440µH at 100kHz. Confirm that the 5000Vrms isolation rating meets your safety compliance requirements. Ensure the physical footprint dimensions align with your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when designing isolated DC/DC converters requiring high isolation voltage in a compact SMD package. It is specifically engineered for use with Texas Instruments SN6505A driver chips. Consider the 150kHz operating frequency and thermal performance within the -40°C to 125°C range during system integration.
Part Context
This transformer is part of the WE-PP MID-PPTI series from Würth Elektronik. The series includes variants optimized for different inductance values and pin configurations. These components are commonly used in solar inverter designs and other applications requiring robust magnetic isolation in small footprints.
Replacement Considerations
Check the official datasheet for alternative part numbers within the same WE-PP series that offer different inductance values or pinouts. Verify compatibility with existing driver ICs such as the SN6505A if substituting with similar models.
