Power adapter MEAN WELL SKM10B-03 10 W Input 18-36 V

The MEAN WELL SKM10B-03 is a compact DC-DC converter designed for PCB mounting with a DIP through-hole package measuring approximately 1" x 1". It accepts an input voltage range of 18–36 Vdc and provides a single regulated output of 3.3 Vdc at up to 2.5 A, delivering a total output power of 10 W. The module is lightweight (about 18 g) and RoHS compliant, intended for integration into electronic assemblies that require a small, stable 3.3 V supply.

Advantages

The SKM10B-03 offers a small footprint and DIP through-hole form factor for easy PCB installation and mechanical stability. Its wide input range (18–36 Vdc) allows use with various battery and intermediate-voltage systems. The regulated 3.3 V output at 2.5 A provides adequate current for many microcontroller, digital logic and low-power communication modules while keeping overall power dissipation to 10 W. Compliance with RoHS ensures compatibility with environmental regulations.

Suitable for (tasks / use cases)

• Embedded systems and microcontroller power supply
• Industrial control electronics and signal-conditioning modules
• Communication equipment and low-power networking devices
• Battery-powered systems with intermediate bus voltages
• PCB prototypes and small-volume production circuits

How to use

Mount the SKM10B-03 into the PCB using the DIP through-hole pins, ensuring correct orientation of input and output pins as indicated by the manufacturer’s pinout. Provide proper input connections within the specified 18–36 Vdc range and observe polarity. Place adequate copper area or thermal vias if required by your PCB layout to assist heat dissipation. Verify output voltage under load and ensure the connected downstream circuitry does not draw more than 2.5 A continuous from the 3.3 V output.

Recommendations

Use decoupling capacitors close to the module’s output for improved transient response, include input filtering if the supply source is noisy, and respect the 10 W power limit to avoid thermal shutdown. Follow MEAN WELL’s datasheet for detailed pinout, derating curves and recommended PCB layout for reliable long-term operation.
