## Summary description

MEAN WELL IRM-01-12S is a compact 1 W DC/DC converter designed to provide a regulated 12 V output from a wide 85–305 V input range. It meets RoHS sustainability requirements and is suitable for low-power embedded applications, industrial control boards, signal conditioning and small instrumentation. Small footprint (33.7 mm depth, 15 mm height) and 25.5 g weight simplify integration into space-constrained designs.

## Long description

MEAN WELL IRM-01-12S is a compact DC/DC converter delivering a regulated 12 V output from a wide input range of 85–305 V AC. Designed for low-power applications, this 1 W module provides reliable voltage conversion in a miniature encapsulated SMD package with a small footprint (33.7 mm depth, 15 mm height) and low weight. It conforms to RoHS requirements and is intended for integration on PCBs and in space-constrained electronic designs where stable 12 V rail and isolation are required.
Advantages
The IRM-01-12S offers stable regulation at low load currents with compact dimensions that simplify placement on crowded boards. Its wide 85–305 V AC input range allows global AC mains compatibility without additional components. Encapsulated construction and SMD mounting enable automated assembly and reduce the need for external protection, while RoHS compliance supports environmentally conscious designs.
Suitable for
 Low-power embedded systems and microcontroller boards
 Industrial control and monitoring modules
 Signal conditioning and small instrumentation
 Telecom and network accessory devices with modest power needs
 Space-constrained electronics and compact consumer devices
Key specifications
 Output voltage: 12 V DC
 Output power: 1 W (approximately 0.083 A output current)
 Input voltage range: 85–305 V AC
 Mounting style: SMD (surface-mount device) in encapsulated package
 Dimensions: depth 33.7 mm, height 15 mm (approximate footprint-friendly form factor)
 Weight: approximately 25.5 g
 Environmental: RoHS compliant
How to use
Place the IRM-01-12S on the PCB according to the manufacturer's recommended land pattern and solder using standard SMD reflow or hand-soldering processes suitable for encapsulated modules. Ensure mains input is connected to the correct input pads and the 12 V output is taken from the designated output pads. Observe isolation clearances and follow safety practices when working with high AC voltages. Verify output voltage under expected load conditions and add filtering or decoupling capacitors on the output if required by the application.
Usage recommendations
Use the module within its rated input range and avoid continuous operation near maximum output current to extend service life. Provide adequate spacing from heat-sensitive components and, if required, include input surge protection or additional transient suppression in environments with unstable mains. For critical applications, validate thermal behavior on the target PCB layout and include output filtering to meet downstream noise requirements.
