Τροφοδοτικό MEAN WELL SCW20A-05 20W 5V 4A RoHS

The MEAN WELL SCW20A-05 is a PCB-mount DC-DC converter designed for applications requiring a stable 5V output from a 9–18V DC input. Supplied in a DIP through-hole package, this 20W module provides up to 4A output current and conforms to RoHS environmental requirements, making it suitable for electronics projects and embedded systems that need a compact, board-mounted power solution.

Advantages

The SCW20A-05 delivers a regulated 5V output at up to 4A with a wide 9–18V input range, offering compact PCB-mount installation in a DIP through-hole form factor. Its RoHS compliance ensures reduced hazardous substances, and its 20W power rating supports a variety of low-voltage loads while simplifying board-level power design.

Suitable for

• Embedded systems and single-board computers
• Industrial control and automation electronics
• Consumer electronics and peripheral devices
• Prototyping and electronic development boards

How to use

Mount the SCW20A-05 on the circuit board using the DIP through-hole pins, ensuring correct orientation and solid solder joints. Connect a 9–18V DC supply to the input pins and take the regulated 5V output from the output pins. Observe proper board layout practices for power modules: provide adequate copper area for heat dissipation, keep input and output traces short, and add decoupling capacitors near the load if required by the application.

Recommendations

For reliable operation, ensure the ambient temperature and PCB layout allow sufficient heat dissipation for up to 20W operation. Verify the input supply is within 9–18V and provide appropriate protection (fuses or transient suppression) if the environment or connected equipment requires it.
