Fonte de alimentação MEAN WELL SPAN02A-12 2 W 12 V 0,167 A RoHS

The MEAN WELL SPAN02A-12 is a compact DC-DC converter designed for PCB mounting in a SIP through-hole package. It accepts an input voltage range of 9–18 V DC and provides a single isolated 12 V DC output rated at 0.167 A (2 W total output). The module is RoHS compliant and intended for use where a small, board-mounted 12 V supply is required.

Advantages

The SPAN02A-12 offers compact PCB-mounted form factor and a SIP through-hole package for straightforward soldering to printed circuit boards. Its input range of 9–18 V DC allows it to be used with common battery and regulated supply voltages. With a fixed 12 V DC single output at 0.167 A, it provides a stable low-power supply while meeting RoHS environmental standards.

Suitable for

• Low-power embedded electronics and control boards
• Signal conditioning and sensor power
• Small industrial modules and instrumentation
• Battery-powered systems operating within 9–18 V input

How to use

Place the SPAN02A-12 into the PCB footprint matching the SIP through-hole pinout and solder according to standard through-hole practice. Apply a DC input voltage within the specified 9–18 V range to the input pins, and take the regulated 12 V output from the output pins. Ensure correct polarity on the input and output connections and allow for adequate spacing or shielding if nearby circuitry is sensitive to switching noise.

Recommendations

Use the converter within its rated input and output limits, provide appropriate decoupling and grounding on the PCB, and avoid exceeding the 0.167 A output current. For reliable operation, maintain ambient temperature and ventilation consistent with the device’s thermal limits and follow MEAN WELL’s application notes where available.
