Power adapter MEAN WELL SFTN01N-12 1 W 12 V 21.6-26.4 V

The MEAN WELL SFTN01N-12 is a compact DC-DC converter in an SMD PCB-mount package, designed to accept an input voltage between 21.6 and 26.4 V DC and provide a single regulated 12 V DC output at up to 0.084 A (1 W). The module includes a 1-second short-circuit protection feature and complies with RoHS requirements.

Advantages

The SFTN01N-12 offers a small footprint for PCB integration, stable 12 V output at low power consumption, and built-in short-circuit protection that disconnects during sustained faults for about one second. Its SMD package simplifies assembly for automated manufacturing and helps maintain consistent electrical performance within the specified input range.

Suitable for

• Low-power embedded electronics
• Signal conditioning and sensor modules
• Industrial control circuits requiring 12 V auxiliary supply
• PCB-mounted power sections in compact devices

How to use

Mount the SFTN01N-12 on the PCB following the manufacturer's recommended soldering profile and footprint for SMD components. Apply an input supply within 21.6–26.4 V DC to the converter's input pins and take the regulated 12 V DC from the output pins. Verify correct polarity and connections before powering the board. If a short-circuit occurs, the device provides a ~1 second protection response; clear the fault and reapply power as needed.

Recommendations

Use appropriate input filtering and decoupling on the PCB to minimise noise and meet EMC requirements. Ensure traces and connectors for the 12 V output are sized for the rated current and provide adequate thermal management when integrating the SMD module into densely populated boards.
