Fonte de alimentação MEAN WELL SKMW20F-05 20W 5V 4A RoHS

The MEAN WELL SKMW20F-05 is a compact PCB-mount DC-DC converter designed for applications that require a regulated 5V output from a wide input range. The module accepts 9–36V DC input and delivers a single 5V DC output at up to 4A (20W). Housed in a 1" x 1" DIP through-hole package, it features a remote ON/OFF control and complies with RoHS. Its small size and 18 g weight make it suitable for space-constrained boards and bulk installations.

Advantages

The SKMW20F-05 offers a wide input voltage range that supports various battery and vehicle systems, a stable 5V/4A regulated output, and a compact 1" x 1" footprint for easy PCB integration. The through-hole DIP package simplifies assembly for wave or hand soldering, and the remote ON/OFF function provides convenient system control. RoHS compliance reduces environmental and regulatory concerns for mass production.

Suitable for

• Embedded systems and microcontroller boards requiring a 5V supply
• Automotive or battery-powered equipment operating within 9–36V input range
• Industrial control modules and communication devices with limited PCB space
• Volume manufacturing and OEM assemblies (pack quantity available)

How to use

Mount the SKMW20F-05 onto the PCB using the DIP through-hole pins and solder according to standard soldering practices. Connect a 9–36V DC input to the designated input pins and take the regulated 5V output from the output pins, observing correct polarity. Use the remote ON/OFF pin to enable or disable the output as needed; refer to the manufacturer's datasheet for the required control logic levels and recommended connection circuits. Ensure adequate PCB layout and grounding for thermal dissipation and stable operation.

Recommendations

For reliable operation, keep input voltage within the 9–36V range, provide proper decoupling on the 5V output, and follow MEAN WELL’s recommended PCB layout and thermal guidelines. Verify compatibility with your system’s inrush and transient conditions and consider fusing or transient suppression on the input for protection.
