Fonte de alimentação MEAN WELL SFTN01N-05 1W 5V entrada 21,6–26,4V

The MEAN WELL SFTN01N-05 is a compact PCB-mount DC-DC converter designed for low-power applications. It provides a single 5V DC output at 0.2A (1W) from an input range of 21.6–26.4V DC. The module is supplied in an SMD package with a low profile (depth 15.2 mm) and meets RoHS requirements, making it suitable for space-constrained, compliant electronic designs.

Advantages

The SFTN01N-05 offers a small footprint and low profile for easy integration on populated PCBs, stable 5V output for powering small electronics, and built-in protection with a 1 second short-circuit protection feature. Its SMD package simplifies automated assembly and the RoHS compliance supports environmentally regulated projects.

Suitable for

• Powering small electronic modules and sensors
• Embedded systems with limited board space
• Industrial or commercial devices requiring regulated 5V at low current
• Automated PCB assembly where SMD components are preferred

How to use

Place and solder the SFTN01N-05 onto the PCB according to the manufacturer’s recommended footprint. Apply an input supply within 21.6–26.4 V DC to the converter input terminals and verify the output is 5 V DC before connecting load devices. Observe polarity and grounding practices when wiring. If a short occurs, the converter provides approximately 1 second of short protection; remove the fault and power-cycle if necessary.

Recommendations

Use this converter on a PCB with adequate copper area for heat dissipation and avoid exceeding the nominal output current of 0.2 A. Ensure the input supply is stable and filtered; follow MEAN WELL layout and soldering guidelines for reliable long-term operation.
