## Summary description

The MEAN WELL MDS01N-12 is a compact power adapter with an output of 1 W and a voltage of 12 V. It operates with an input voltage range of 21.6 to 26.4 V. This adapter is RoHS compliant, ensuring it meets environmental standards. Ideal for various electronic applications requiring reliable power supply.

## Long description

The MEAN WELL MDS01N-12 is a compact DC-DC medical converter designed for PCB-mounting in a SIP through-hole package. It accepts an input voltage between 21.6 and 26.4 V DC and provides a single 12 V DC output at up to 0.084 A (1 W). The module offers enhanced safety isolation with 2xMOPP suitable for medical applications and is RoHS compliant.
Advantages
The converter's small SIP form factor saves PCB space and allows straightforward through-hole mounting. Low power consumption and a stable 12 V output make it suitable for low-power devices. The 2xMOPP isolation rating provides increased patient and operator protection in medical environments while RoHS compliance ensures reduced hazardous substances.
Suitable for
Low-power medical electronics and monitoring devices
Embedded systems and PCB-integrated power rails
Instrumentation and sensor modules requiring isolated 12 V supply
When it may not be suitable
This converter supplies only 1 W (12 V at 0.084 A), so it is not suitable for applications that require higher currents or power-hungry loads. Because it is a PCB-mounted SIP through-hole module, it may not be appropriate for systems that need fully enclosed external adapters or connectors for frequent user access.
Key specifications
Input voltage: 21.6–26.4 V DC
Output voltage: 12 V DC
Output current: up to 0.084 A (1 W)
Mounting: SIP through-hole (PCB mount)
Isolation: 2×MOPP (medical isolated)
Compliance: RoHS
How to use
Solder the SIP through-hole pins to the PCB according to the manufacturer’s recommended footprint and ensure proper creepage and clearance on the board. Apply an input voltage within 21.6–26.4 V DC and verify the 12 V output under the expected load. Observe standard medical-device assembly procedures and insulation requirements to maintain the 2×MOPP isolation performance.
What to consider before purchase
Required output power and current — rated at 1 W (0.084 A) only
Physical mounting style — SIP through-hole for PCB assembly
Input voltage availability in your system (21.6–26.4 V DC)
Required isolation level for medical applications (2×MOPP)
Usage recommendations
Use this module on PCBs for low-power medical or embedded designs where isolated 12 V is needed; ensure input voltage stability and follow board layout and insulation guidelines to preserve isolation and thermal performance.
