## Summary description

MEAN WELL SPBW03F-03 is a compact power adapter/inverter with an output power of 3 W and output current of 0.7 A. Designed for low‑power applications, it provides regulated DC output suitable for small electronics and LED modules. The unit complies with RoHS requirements. Supplied in bulk packs (quantity per pack: 2576).

## Long description

MEAN WELL SPBW03F-03 is a compact DC‑DC converter designed for PCB mounting and through‑hole SIP installation. With a regulated single output of 3.3 VDC at up to 0.7 A and an input range of 9–36 VDC, this 3 W power module is intended for low‑power electronics and LED modules that require stable voltage conversion on printed circuit boards. The converter meets RoHS requirements and is supplied in bulk packaging for volume assembly.
Advantages
The module offers a wide input voltage range and a stable 3.3 V output at 0.7 A in a small SIP through‑hole package suitable for direct PCB mounting. Its compact size and regulated output simplify power design for low‑power devices, while RoHS compliance supports environmentally conscious manufacturing. The device's single output and straightforward pinout reduce design complexity for embedded systems.
Suitable for
 Low‑power embedded electronics and microcontroller boards
 LED modules and lighting control circuits
 Battery‑powered systems requiring step‑down conversion
 Industrial and instrumentation PCBs with limited space
Key specifications
 Type: DC‑DC converter, PCB mount, SIP through‑hole package
 Input voltage range: 9–36 VDC
 Output: single regulated 3.3 VDC
 Maximum output current: 0.7 A
 Output power: 3 W
 Mounting: through‑hole SIP for direct PCB insertion
 Standards: RoHS compliant
How to use
Install the converter into the PCB using the SIP through‑hole pins and solder according to standard through‑hole soldering practices. Apply an input voltage within the specified 9–36 VDC range and verify correct polarity before power‑up. Connect the 3.3 V output to the target circuit, ensuring the load does not exceed 0.7 A. Provide adequate PCB copper area or heatsinking if continuous operation near maximum load is expected, and include input/output decoupling components as recommended by the system designer to minimize noise.
Usage recommendations
Use within the specified input range and avoid sustained operation at maximum current without adequate thermal management. Place the module clear of high‑temperature components and plan PCB layout to allow airflow. Add filtering and transient protection on the input if the converter is used in electrically noisy environments.
