Power adapter/inverter MEAN WELL SFTN02N-12, input 21.6–26.4 V, output 12 V, 2 W, RoHS, depth 15.2 mm

MEAN WELL SFTN02N-12 is a compact PCB-mount DC–DC converter designed for low-power applications. The module accepts an input voltage from 21.6 to 26.4 VDC and provides a single isolated 12 VDC output with a nominal output current of 0.167 A (2 W). Its small SMD package and shallow depth (15.2 mm) make it suitable for embedded systems and space-constrained installations; the device is RoHS compliant.

Advantages

The SFTN02N-12 offers a small footprint and SMD mounting for automated assembly, an isolated single 12 V output for separation between input and load, and built-in short-circuit protection that responds within 0.5 seconds. The unit’s 2 W rated power and standardized package support integration into compact electronic designs and high-volume production.

Suitable for

• Embedded systems and single-board computers
• Industrial control modules with limited space
• Sensor interfaces and low-power peripherals
• Applications requiring isolated 12 V supply from ~24 V sources

How to use

Mount the SFTN02N-12 on the PCB according to the manufacturer’s recommended footprint and soldering profile for SMD devices. Apply an input voltage within 21.6–26.4 V DC to the designated input pins and take the 12 V DC output from the output pins. Observe correct polarity and maintain adequate creepage and clearance for isolation. Allow for ventilation and avoid exceeding the rated output current and power to prevent thermal stress.

Recommendations

For reliable operation, ensure the input source is regulated near 24 V, keep ambient temperature within the device’s specified range, and follow MEAN WELL’s PCB layout and soldering guidelines. Use appropriate filtering on input and output lines if the application is sensitive to noise.
