## Summary description

The MEAN WELL DPBW03F-12 is a compact power adapter with an output power of 3 W, output voltage of 12 V, and output current of 0.125 A. It complies with RoHS standards, ensuring environmental safety. Ideal for various electronic applications requiring reliable power supply.

## Long description

The MEAN WELL DPBW03F-12 is a compact DC-DC converter in a SIP through-hole package designed for PCB mounting. It accepts an input range of 9–36 VDC and provides dual outputs of ±12 VDC at up to 0.125 A each. The module delivers 3 W total output power and meets RoHS requirements, making it suitable for space-constrained electronic designs that need isolated bipolar supply rails.
Advantages
The DPBW03F-12 offers a small footprint and through-hole SIP form factor for straightforward PCB assembly. Its wide input range (9–36 VDC) accommodates varied source voltages, while dual ±12 V outputs supply bipolar circuits without needing additional converters. RoHS compliance ensures reduced hazardous substances in manufacturing.
Suitable for
 PCB-mounted signal conditioning and analog circuitry requiring ±12 V rails
 Embedded systems and industrial control boards with 9–36 V supply
 Communication and instrumentation modules needing isolated bipolar outputs
Key specifications
 Manufacturer: MEAN WELL
 Model / MPN: DPBW03F-12
 Input voltage: 9–36 VDC
 Output: Dual ±12 VDC
 Output current: 0.125 A per rail
 Total output power: 3 W
 Package: SIP through-hole (PCB mount)
 Standards: RoHS compliant
 EAN: 4021087046336
How to use
Mount the DPBW03F-12 into the designated SIP through-hole footprint on the PCB and solder it following standard reflow or wave soldering guidelines for through-hole components. Connect the input to a DC source within 9–36 VDC and route the ±12 V outputs to the target circuits. Observe correct polarity and isolation clearances when integrating the converter into assemblies that require separation between input and output grounds.
Usage recommendations
For reliable operation, ensure adequate PCB layout practices: provide thermal relief and sufficient copper area for heat dissipation, maintain recommended input and output decoupling, and follow MEAN WELL application notes for isolation and grounding. Avoid operating at maximum ratings continuously and allow margin in input voltage and current to extend service life.
