Napájací zdroj MEAN WELL DPBW03F-12 3 W 12 V 0,125 A RoHS

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

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.

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.
