## Summary description

The MEAN WELL SCW20B-05 is a reliable power adapter with an input voltage range of 18-36V and an output power of 20W at 5V. It is RoHS compliant, ensuring environmental safety. Ideal for various electronic applications requiring stable power supply.

## Long description

The MEAN WELL SCW20B-05 is a compact DC-DC converter designed for PCB mounting in a DIP through-hole package. It accepts a wide input range of 18–36 VDC and provides a regulated 5 VDC output capable of delivering up to 4 A (20 W). The module is RoHS-compliant and intended for use where a stable low-voltage supply is required on printed circuit boards.
Advantages
The SCW20B-05 offers a wide input voltage range and a stable 5 V output with up to 4 A current, enabling use with varying battery or intermediate bus voltages. Its DIP through-hole construction simplifies PCB mounting and prototyping. RoHS compliance ensures it meets common environmental and safety standards for electronic assemblies.
Suitable for
 Embedded systems and single-board computers requiring 5 V power
 Industrial control modules with 18–36 V supply rails
 Battery-powered equipment and automotive intermediate bus voltage conversion (within input range)
 Prototyping and low-volume production on PCBs using through-hole components
Key specifications
 Input voltage: 18–36 VDC
 Output voltage: 5 VDC
 Output current: up to 4 A (20 W)
 Package: DIP through-hole for PCB mount
 Compliance: RoHS
How to use
Mount the SCW20B-05 into the PCB using the specified through-hole footprint and solder the pins following standard PCB assembly procedures. Apply a DC input within the 18–36 V range to the input pins, and verify the output on the 5 V pins with a multimeter before connecting sensitive loads. Ensure adequate copper area or heat dissipation measures on the PCB if the converter operates near its maximum load to maintain reliable performance.
Usage recommendations
For best results, avoid operating continuously at the maximum 4 A output without thermal management; provide sufficient PCB copper and airflow. Verify input polarity and decoupling on the input and output as recommended by standard DC-DC converter practice to reduce noise and ensure stable 5 V output.
