Power adapter/inverter mean well SFTN02M-05, 2 W, input 10.8–13.2 V, output 5 V, RoHS

Mean Well SFTN02M-05 is a compact PCB-mount DC-DC converter providing a regulated 5 V output from a 10.8–13.2 V DC input. Rated at 2 W continuous power and supplied in an SMD package with a shallow 15.2 mm depth, it is intended for embedded electronics and industrial control modules where a small, board-mounted 5 V supply is required.

Advantages

The SFTN02M-05 offers a stable 5 V output at up to 0.4 A with built-in short-circuit protection that limits fault duration to 0.5 seconds. Its RoHS compliance and SMD PCB-mount format simplify integration into automated production and compact assemblies. The adapter’s regulated output and small footprint reduce the need for additional regulation components on the board.

Suitable for

• Embedded electronics and single-board systems
• Industrial control modules and automation equipment
• Small devices and sensors requiring a 5 V supply
• Volume production and automated PCB assembly

How to use

Mount the SFTN02M-05 on the PCB according to the manufacturer’s recommended footprint and soldering profile for SMD parts. Connect the input to a stable 10.8–13.2 V DC source and route the 5 V output to the application circuitry, observing proper polarity and adequate decoupling. Ensure the output load does not exceed 0.4 A continuous to avoid thermal or protection trips.

Recommendations

For reliable operation, provide adequate PCB copper area for heat dissipation, use input filtering if the supply is noisy, and verify solder joints after reflow. In designs where continuous higher current is required, choose a converter with suitable higher output current rating.
