## Summary description

MEAN WELL SPAN02C-03 is a compact power adapter/inverter with an input voltage range of 36–75 V and a fixed output power of 2 W with up to 0.5 A output current. Designed for low-power DC applications, it meets RoHS sustainability requirements. Typical uses include powering small electronics, sensors, and control modules where a stable low-power DC source is needed.

## Long description

MEAN WELL SPAN02C-03 is a compact DC-DC converter in a SIP through-hole package designed for PCB mounting. It accepts a wide input range of 36–75 V DC and provides a single fixed low-voltage output suitable for low-power electronics. The module delivers 3.3 V DC at up to 0.5 A with a rated output power of 2 W and is compliant with RoHS requirements, making it appropriate for industrial and embedded applications where a small, stable power source is required.
Advantages
The converter combines a wide input voltage range and regulated low-voltage output in a compact, easy-to-mount format, enabling space-saving designs on PCBs. The SIP through-hole package simplifies mechanical installation and soldering for reliable board-level connections. Low output power and efficient conversion reduce thermal stress in enclosed systems, while RoHS compliance supports environmentally conscious product design.
Suitable for
 Powering small electronic modules and sensors requiring 3.3 V DC
 Embedded control boards and low-power communication modules
 Industrial and instrumentation applications with 36–75 V supply rails
 PCB-mounted power supply sections in compact devices
Key specifications
 Input voltage range: 36–75 V DC
 Output voltage: 3.3 V DC
 Maximum output current: 0.5 A
 Rated output power: 2 W
 Package type: SIP through-hole for PCB mounting
 Regulation type: fixed single output
 RoHS environmental compliance
How to use
Mount the unit on a PCB using the SIP through-hole pins and ensure correct polarity of the input supply. Provide a stable DC input within the 36–75 V range and verify that connected loads do not exceed the 0.5 A output current rating. Allow for minimal clearance around the module for heat dissipation and follow standard PCB layout practices for power converters, including input decoupling and grounding. Test the assembled board under expected load conditions to confirm stable 3.3 V output and acceptable temperature rise.
Usage recommendations
For reliable operation, avoid continuous operation at full load in high ambient temperatures; provide adequate ventilation or heat sinking on the PCB. Use input transient protection if the supply may be subject to spikes and follow EMC layout guidelines to minimize interference with nearby sensitive circuits.
