## Long description

The MEAN WELL SPBW03G-03 is a compact PCB-mount DC-DC converter designed for single-output applications. It accepts a wide input voltage range of 18–75 V DC and delivers a regulated 3.3 V DC output with a maximum current of 0.7 A. The module is supplied in an SIP through-hole package and is RoHS compliant.
Advantages
The SPBW03G-03 offers a wide input range that supports various supply sources, a small footprint for PCB mounting, and a fixed 3.3 V output for straightforward integration into low-voltage systems. Its through-hole SIP package eases assembly for both prototyping and production, and RoHS compliance ensures it meets environmental standards.
Suitable for
 Embedded systems requiring 3.3 V power
 Industrial control boards with 18–75 V supplies
 Communication modules and sensors
 Bulk manufacturing and OEM projects
Key specifications
 Manufacturer: mean well
 Model / MPN: SPBW03G-03
 Input voltage: 18–75 V DC
 Output voltage: 3.3 V DC
 Maximum output current: 0.7 A
 Output power: 3 W
 Package: SIP through-hole
 Compliance: RoHS
 EAN: 4021087040952
How to use
Mount the SPBW03G-03 on the PCB using the SIP through-hole pins, ensuring correct orientation for input and output terminals. Connect a suitable 18–75 V DC source to the input pins and route the 3.3 V output to the load, taking into account the 0.7 A current limit. Provide appropriate input and output decoupling capacitors on the PCB if required by the application, and observe correct polarity during wiring.
Usage recommendations
For reliable operation, keep the module within its specified input range and avoid continuous operation at the maximum output current without proper thermal management. Follow PCB layout guidelines for DC-DC converters, place decoupling capacitors close to the device pins, and ensure adequate airflow or heatsinking if the ambient temperature or load conditions require it.
