Power Adapter MEAN WELL DPBW03F-05 3W 5V 0.3A RoHS

The MEAN WELL DPBW03F-05 is a compact DC-DC converter designed for PCB mounting in a SIP through-hole package. It accepts a wide input voltage range of 9–36 Vdc and provides a dual output of ±5 Vdc with a rated output current of 0.3 A, delivering up to 3 W of output power. The module is RoHS compliant and intended for low-power embedded and industrial applications that require stable bipolar rails from a single input source.

Advantages

The DPBW03F-05 offers a small footprint suitable for space-constrained PCBs, a wide input voltage range for flexible system designs, and dual bipolar outputs that simplify powering analog circuits or signal conditioning stages. Its through-hole SIP package enables secure mechanical mounting and easy soldering on standard PCB manufacturing lines. RoHS compliance ensures adherence to common environmental regulations.

Suitable for

• Embedded systems and microcontroller boards requiring ±5 V rails
• Sensor signal conditioning and low-power analog circuitry
• Industrial control modules with a 9–36 Vdc supply
• Prototyping and small-volume appliance designs

How to use

Mount the DPBW03F-05 in a compatible PCB footprint using standard through-hole soldering techniques, ensuring correct polarity and secure mechanical attachment. Connect a 9–36 Vdc input supply to the input pins and take the ±5 V outputs from the respective output pins, observing the module's current limits. Provide suitable input and output decoupling capacitors on the PCB if required by your design guidelines and follow the manufacturer's recommended layout to minimize noise and ensure thermal dissipation.

Recommendations

Use the converter within its specified input range and avoid exceeding the 0.3 A output current per rail. Ensure adequate board-level thermal management and place input/output filtering close to the module pins to maintain stable bipolar outputs in sensitive analog or mixed-signal applications.
