Product information

Description

The MEAN WELL SCWN03A-12 is a compact DC-DC regulated single output converter delivering 12V at 0.25A (3W) from a 9–18V DC input. It features 3000VDC input-to-output isolation and comes in a DIP through-hole package suitable for PCB mounting. The unit is RoHS compliant.

Advantages

This module provides a regulated 12V output with low power consumption in a small DIP package, allowing straightforward integration into existing PCBs. High input-to-output isolation (3000VDC) improves safety in applications requiring galvanic separation. The wide input range (9–18V) offers flexibility for various DC supplies.

Suitable for

  • Powering low-power embedded systems and microcontroller boards
  • Industrial control circuits requiring isolation
  • Sensor modules and instrumentation with 12V requirements
  • Prototyping and through-hole PCB designs

Key specifications

  • Model: MEAN WELL SCWN03A-12 (MPN: SCWN03A-12)
  • Input voltage: 9–18 V DC
  • Output voltage/current: 12 V DC, 0.25 A (3 W)
  • Isolation: 3000 V DC input-to-output
  • Package: DIP through-hole
  • Compliance: RoHS

How to use

Mount the SCWN03A-12 on the target PCB using standard DIP through-hole soldering methods. Connect a 9–18V DC supply to the input pins, observing polarity. Take the regulated 12V output from the output pins, ensuring the load does not exceed 0.25A. Follow normal PCB layout practices for power modules, keeping input and output traces adequately sized.

Usage recommendations

Use the converter within the specified input range and do not exceed the 0.25A output current. Provide appropriate decoupling and, if needed, input fusing. Maintain clearance and creepage distances on the PCB consistent with the 3000V isolation rating and follow manufacturer guidelines for reliable long-term operation.
