Power adapter MEAN WELL SFTN01L-05 1 W Input 4.5-5.5 V Output 5 V

The MEAN WELL SFTN01L-05 is a compact PCB-mount DC-DC converter designed for low-power applications. It accepts an input voltage range of 4.5–5.5 V DC and provides a regulated 5 V DC single output with a maximum output current of 0.2 A (1 W). The module is supplied in an SMD package with a shallow depth of 15.2 mm and meets RoHS requirements.

Advantages

The SFTN01L-05 offers a small footprint and SMD mounting for easy integration into space-constrained designs. It delivers a stable 5 V output from inputs typical of USB or other 5 V rails and includes a short-circuit protection feature that responds within approximately one second. The device’s compliance with RoHS facilitates use in regulated manufacturing environments.

Suitable for

• Embedded systems and small single-board computers
• USB-powered devices and peripherals
• Industrial control modules with limited space
• Batch production and OEM assemblies

How to use

Mount the SFTN01L-05 on the PCB following the manufacturer’s SMD footprint and soldering guidelines. Connect the input to a stable 4.5–5.5 V DC supply and take the regulated 5 V output from the designated output pads. Ensure adequate PCB copper area for thermal dissipation and follow normal precautions for handling SMD components. Observe polarity when connecting input and output lines.

Recommendations

For reliable operation, avoid continuous operation at the maximum output current and provide adequate trace width or thermal vias to dissipate heat. If a short-circuit occurs, allow the device to recover after the short is cleared; repeated short events should be investigated to prevent damage to surrounding circuitry.
