How to use

Mount the DCWN03B-15 in a compatible through-hole footprint on the PCB, ensuring correct pin orientation for input, output and ground connections. Apply a DC input between 18 and 36 V and verify the output rails with a meter before connecting sensitive circuitry. Provide adequate clearance and common-mode considerations to maintain the specified 3000 VDC isolation. Follow the manufacturer's layout recommendations for grounding and decoupling to ensure stable regulation.

Recommendations

Use appropriate input filtering and transient protection on the 18–36 VDC supply, avoid exceeding the ±0.1 A output current, and keep the device within recommended ambient temperature limits. For applications requiring higher current or additional protections, select a converter with suitable ratings.
