• Surface mount construction utilizing EP10 package format
• Compliance with RoHS3 environmental regulations

Applications

• Switch-mode power supply circuits
• Isolated DC-DC conversion systems
• Electronic equipment requiring 3.3 V regulated output

Procurement Notes

Verify the specific datasheet version and mechanical dimensions prior to integration, as manufacturer documentation may undergo updates. Confirm that the EP10 footprint matches the target PCB layout. Ensure thermal management strategies align with the 130°C maximum operating temperature rating. Cross-reference the pinout configuration against the official product specification sheet to prevent wiring errors during assembly.

Selection Notes

Select this component when a compact, surface-mount solution is required for low-voltage isolated power stages. The 50.5 µH primary inductance and 200 kHz frequency capability suit high-density designs. Verify compatibility with the 18–75 V input range and 3.3 V output requirement. Consider the physical dimensions of 13.08 mm x 15.24 mm x 11.45 mm for spatial constraints in the final enclosure design.
