Power adapter MEAN WELL SKM10E-05 10 W 5 V 2 A RoHS

The MEAN WELL SKM10E-05 is a compact PCB-mount DC-DC converter designed for board-level power conversion. It accepts an input voltage range of 4.7–9 V DC and provides a regulated single output of 5 V DC at up to 2 A (10 W). The module is supplied in a DIP through-hole package with an ultra-compact 1" x 1" footprint and a lightweight construction of approximately 18 g, suitable for space-constrained applications and volume assembly.

Advantages

The module delivers a stable 5 V output at 2 A in a small DIP through-hole form factor suitable for PCB mounting. Its wide-ish input range allows use with various battery and regulated supply sources. Compliance with RoHS ensures reduced hazardous substances, and the low weight and 1" x 1" size simplify integration into compact devices and multi-board systems.

Suitable for

• Embedded systems and microcontroller boards
• Industrial control modules and instrumentation
• Battery-powered devices where step-up/step-down regulation is needed
• Mass production and panel assembly requiring through-hole mounting

How to use

Solder the converter into the appropriate through-hole footprint on the PCB following the manufacturer’s pinout. Provide an input supply within the specified 4.7–9 V DC range and verify correct polarity before powering. Connect the 5 V output to the load, ensuring that the load current does not exceed 2 A. For initial testing, power up the board without the final load and measure the output voltage to confirm regulation.

Recommendations

Use short, low-impedance traces for input and output lines and place recommended input/output decoupling capacitors near the pins if the application involves high transient currents. Maintain adequate spacing from heat-sensitive components; although compact, the converter dissipates power near its rating and benefits from airflow or a heatsink on the PCB if sustained currents approach 2 A.
