## Long description

The MEAN WELL SPAN02B-05 is a compact DC-DC converter designed for PCB mounting in a SIP through-hole package. It accepts an input voltage range of 18–36 VDC and provides a regulated single output of 5 VDC at up to 0.4 A (2 W total). The module is RoHS compliant and intended for use in small electronic devices and embedded systems where a stable 5 V supply is required from a higher DC bus.
Advantages
The SPAN02B-05 offers a small footprint and a through-hole SIP package suitable for reliable PCB connections. Its wide input range (18–36 V) allows compatibility with various DC supply sources. The fixed 5 V output at 0.4 A provides a simple solution for powering logic circuits, sensors, and control electronics without additional regulation. RoHS compliance ensures it meets common environmental and assembly standards.
Suitable for
Embedded systems and microcontroller boards requiring 5 V from a higher DC voltage
Industrial control modules with 18–36 V supply rails
Sensor interfaces and low-power peripherals
Prototyping and PCB-mounted power solutions
Key specifications
Manufacturer: MEAN WELL
Model (MPN): SPAN02B-05
Input voltage: 18–36 VDC
Output: 5 VDC, 0.4 A (2 W)
Package: SIP through-hole PCB mount
Compliance: RoHS
EAN: 4021087041102
How to use
Mount the SIP through-hole pins into the PCB and solder according to good soldering practice, observing polarity for input and output connections. Provide an input DC supply within the specified 18–36 V range. Connect the 5 V output to the target circuit, ensuring the load does not exceed 0.4 A. Allow for appropriate PCB copper area or heatsinking if operating near maximum load to maintain stable temperature and performance.
Usage recommendations
Use appropriate input filtering and a fuse on the input rail for protection. Verify input and output polarity before powering the board. For critical applications, test the converter under expected temperature and load conditions to confirm it meets system requirements.
