## Summary description

MEAN WELL SCW20B-12 is a 20 W power adapter/inverter with an input voltage range of 18–36 V and a fixed 12 V output. Designed for DC–DC conversion in industrial and vehicle applications, it provides regulated 12 V power for electronics, control units, and small devices. RoHS compliant; available in bulk pack quantities.

## Long description

MEAN WELL SCW20B-12 is a compact DC–DC converter providing a regulated 12 V output from a wide 18–36 V DC input. Housed in a through-hole DIP package suitable for PCB mounting, this 20 W module is intended for applications where space-efficient, board-level power conversion is required. It delivers up to 1.67 A at 12 V and is RoHS compliant, offering a reliable solution for powering control electronics and small devices in industrial and vehicle environments.
Advantages
The module combines a wide input range with a fixed, well-regulated 12 V output, simplifying power design for systems operating from varying DC sources. Its through-hole DIP form factor enables secure PCB mounting and straightforward mechanical integration. With a 20 W power rating and thermal design appropriate for board-level use, it supports continuous operation for low- to moderate-power loads while meeting RoHS environmental requirements.
Suitable for
Vehicle electronics powered from 18–36 V onboard supplies
Industrial control circuits and automation boards
Embedded systems and small devices requiring a stable 12 V rail
PCB-level power distribution in equipment and instrumentation
Key specifications
Input voltage range: 18–36 V DC
Output voltage: fixed 12 V DC
Maximum output current: 1.67 A
Output power: 20 W
Package type: through-hole DIP for PCB mounting
Function: DC–DC conversion (isolated/non-isolated status as per manufacturer design)
Compliance: RoHS
How to use
Mount the converter on the PCB using the through-hole pins, ensuring correct orientation and sufficient solder joints for mechanical stability. Connect a suitable 18–36 V DC input source to the input terminals and take the regulated 12 V output from the designated output pins. Provide adequate copper area or heatsinking on the PCB if operating near the maximum power rating to help dissipate heat. Observe standard PCB layout practices for DC–DC converters: keep input and output traces short, place decoupling components close to the pins, and maintain clearance from heat-sensitive components.
Usage recommendations
Verify the input voltage remains within the 18–36 V range and ensure the connected load does not exceed 1.67 A. For reliable long-term operation, allow headroom under the maximum power rating and follow the manufacturer’s guidelines for ambient temperature and airflow. When used in vehicle environments, protect connections against vibration and transient voltage events using appropriate fuses or transient suppression devices.
