Power adapter MEAN WELL SCWN03E-03 3 W 0.6 A RoHS

The MEAN WELL SCWN03E-03 is a compact DC-DC regulated single output converter that accepts 4.5–9 V DC input and provides a stable 3.3 V DC output at up to 0.6 A. The module features 3000 VDC input-to-output isolation and is supplied in a DIP through-hole package. It is RoHS compliant and designed for use where a small, isolated 3.3 V supply is required.

Advantages

This power adapter offers regulated output voltage with low footprint and through-hole DIP packaging for straightforward PCB mounting. The 3000 VDC isolation between input and output increases safety and reduces interference risks in mixed-signal systems. RoHS compliance ensures the device meets environmental material restrictions.

Suitable for

• Embedded systems and microcontroller boards requiring isolated 3.3 V rails
• Industrial control modules with limited PCB space
• Signal conditioning and sensor interfaces needing galvanic isolation
• Prototyping and retrofit applications using through-hole components

How to use

Install the SCWN03E-03 into a compatible PCB using the through-hole DIP pins and ensure correct input polarity before applying power. Provide an input supply within the specified 4.5–9 V DC range. Verify thermal conditions and maintain adequate spacing from heat-sensitive components. Connect the 3.3 V output to the target circuit, respecting the 0.6 A maximum current rating.

Recommendations

For reliable operation, avoid exceeding the 0.6 A output current and operate within the specified input voltage range; allow for cooling and follow PCB layout guidelines for isolation and creepage distances when placing nearby conductors or high-voltage circuits.
