## Long description

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)
