How to use

Mount the SCWN06B-03 into a PCB using the DIP through-hole footprint matching the module pinout. Apply a DC input within the specified 18–36 V range to the input pins and obtain the regulated 3.3 V output from the corresponding output pins. Observe correct polarity when connecting input and output and follow standard PCB design practices for grounding and thermal management. Verify connections and output voltage before connecting sensitive loads.

Recommendations

Use the converter within its specified input range and output load to ensure reliable operation. Provide adequate clearance and creepage distances on the PCB to maintain the 3000 V isolation. For best performance, place decoupling capacitors near the load and avoid exposing the module to temperatures or mechanical stresses beyond the manufacturer's guidelines.
