Power adapter/inverter MEAN WELL SFTN02M-12 — 12 V output, 2 W, input 10.8–13.2 V, RoHS

MEAN WELL SFTN02M-12 is a compact PCB-mount DC-DC converter/inverter that provides a regulated 12 V output at up to 0.167 A (2 W) from a 10.8–13.2 V DC input. Housed in an SMD package with a depth of 15.2 mm, this module is designed for space-constrained installations and high-volume OEM assemblies and complies with RoHS requirements.

Advantages

The SFTN02M-12 offers a small footprint and surface-mount packaging for straightforward PCB assembly, stable 12 V output for low-power loads, and built-in short-circuit protection that responds within 0.5 seconds. Its narrow input range makes it suitable for systems powered from nominal 12 V sources, while RoHS compliance ensures conformity with common environmental standards.

Suitable for

• Low-power embedded electronics requiring a regulated 12 V supply
• Automotive and vehicle systems with a nominal 12 V battery input (within 10.8–13.2 V)
• Space-limited OEM assemblies and high-volume PCB production

How to use

Mount the SFTN02M-12 on the PCB according to the manufacturer’s recommended footprint and soldering profile for SMD components. Apply a DC input within the specified 10.8–13.2 V range and observe correct polarity. Connect the load to the 12 V output, ensuring the current does not exceed 0.167 A. If a short-circuit occurs, the converter provides protection that engages within approximately 0.5 seconds; remove the fault and allow the module to recover according to the system design.

Recommendations

For reliable operation, keep ambient temperature within the component’s allowable range and provide adequate PCB copper area for heat dissipation. Verify that the system’s input voltage stays inside the specified 10.8–13.2 V window and ensure connected loads remain below the 0.167 A rating to prevent repeated activation of short-circuit protection.
