Switching Converter, SMPS Transformers Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant and tape/reel configuration match your assembly requirements. Confirm that the 250 mA current rating and 420 kHz operating frequency align with your circuit design constraints. Check for any recent Product Change Notifications regarding material or manufacturing updates before finalizing procurement.

Switching Converter, SMPS Transformers Selection Notes

Select this component when a dedicated gate drive transformer is required for push-pull topologies rather than general-purpose isolation. Ensure the 5 V primary and 15 V secondary voltage levels suit your driver IC output and switch gate requirements. Consider the 86 μH inductance and 300 nH leakage inductance for timing accuracy in high-speed switching environments.

Switching Converter, SMPS Transformers Part Context

This part belongs to the WE-PSPA series of push-pull and gate drive transformers from Würth Elektronik. These components are engineered for compact surface-mount applications where high isolation voltage and precise magnetic coupling are critical.
