Τροφοδοτικό MEAN WELL SFTN01L-12 1W 12V είσοδος 4,5-5,5V

The MEAN WELL SFTN01L-12 is a compact PCB-mount DC-DC converter that accepts 4.5–5.5 VDC input and provides a single 12 VDC output at up to 0.084 A (1 W). Designed for space-constrained installations, the module uses an SMD package, offers one-second short-circuit protection, and complies with RoHS requirements. Its shallow depth (15.2 mm) makes it suitable for embedded electronic designs and small power-supply applications.

Advantages

The adapter delivers regulated 12 V output from low-voltage 4.5–5.5 V supplies while occupying minimal PCB area thanks to its SMD package. Built-in one-second short protection improves safety during transient faults. RoHS compliance ensures compatibility with lead-free manufacturing processes. The low-profile design (15.2 mm depth) facilitates integration into compact devices.

Suitable for (tasks / use cases)

• Embedded systems and single-board computers requiring a 12 V rail from a 5 V source
• Industrial control modules with limited board space
• Portable equipment and battery-powered devices with regulated 12 V needs
• Prototyping and small-power auxiliary circuits

How to use

Mount the SFTN01L-12 to the PCB according to the manufacturer’s recommended footprint and soldering profile for SMD components. Apply a 4.5–5.5 V DC input to the designated input pads and verify correct polarity before power-up. Connect the 12 V output to the load, ensuring the load current does not exceed 0.084 A. If a short circuit occurs, the module provides approximately one second of protection; remove the fault and allow the module to recover before reapplying power.

Recommendations

For reliable operation, provide adequate PCB copper area for heat dissipation and follow MEAN WELL’s layout and soldering recommendations. Keep input and output traces separate to minimize noise coupling and add filtering or decoupling capacitors at the input and output if the application requires low output ripple or additional transient suppression.
