Power Adapter MEAN WELL SKM10A-05 10W 5V 2A RoHS

The MEAN WELL SKM10A-05 is a compact DC-DC converter designed for PCB mounting, providing a regulated single output of 5 V DC at up to 2 A from a 9–18 V DC input. Housed in a 1" x 1" DIP through-hole package and weighing approximately 18 g, this 10 W module is RoHS compliant and intended for integration where a small, stable 5 V supply is required.

Advantages

This PCB-mount DC-DC converter delivers a reliable 5 V/2 A output in an ultra-compact 1" x 1" through-hole package, simplifying installation on standard PCBs. The module’s wide input range (9–18 V DC) accommodates various power sources, and RoHS compliance ensures adherence to environmental standards. At around 18 g and 10 W output power, the adapter offers a space-saving solution for low-power electronic designs.

Suitable for

• Embedded systems and single-board computers requiring a 5 V supply
• Industrial control circuits and instrumentation with 9–18 V input rails
• Prototyping and compact PCB designs needing a through-hole DC-DC module

How to use

Mount the module into the PCB using the DIP through-hole pins and ensure correct polarity on the input. Provide an input supply within the specified 9–18 V DC range and verify the output with a multimeter before connecting sensitive loads. Observe thermal conditions during operation and allow adequate PCB copper area or ventilation if the module is used near its maximum 10 W rating.

Recommendations

For stable long-term operation, use proper input decoupling and follow MEAN WELL’s layout recommendations: keep input and output traces short, provide sufficient ground plane, and avoid placing heat-sensitive components close to the module. Verify that the input source can supply the required current with margin and consider adding transient protection if the input is noisy.
