Alimentatore MEAN WELL SPAN02B-12 2W ingresso 18-36V uscita 12V

The MEAN WELL SPAN02B-12 is a compact DC-DC converter designed for PCB mounting in a SIP through-hole package. It accepts a wide input range of 18–36 VDC and provides a regulated single output of 12 VDC at up to 0.167 A (2 W total). The module is RoHS compliant and intended for applications that require a small, reliable isolated or non-isolated power source on a printed circuit board.

Advantages

The SPAN02B-12 offers stable 12 V output within a broad input range, a compact SIP through-hole form factor for straightforward PCB installation, and low power dissipation suitable for low-current electronics. RoHS compliance ensures it meets common environmental and safety directives. Its fixed single-output design simplifies integration into power rails that require a small, dedicated 12 V supply.

Suitable for

• Embedded electronics and control boards
• Sensors, communication modules, and low-power peripherals
• Prototyping and small-scale industrial equipment

How to use

Mount the SPAN02B-12 into the designated SIP through-hole footprint on the PCB, ensuring correct polarity for input and output pins. Provide an input supply between 18 and 36 VDC and connect the 12 VDC output to the load requiring up to 0.167 A. Follow standard PCB layout practices for power modules: keep traces short for input and output, place decoupling capacitors as recommended in your design, and ensure adequate spacing from heat-sensitive components.

Recommendations

Use the converter within its specified input and output ratings and avoid exceeding 0.167 A output current. Verify thermal conditions on the board during operation and provide adequate cooling or spacing if the surrounding components heat up.
