## Summary description

MEAN WELL SMU02L-12 is a compact power adapter/inverter providing 2 W output power with a 12 V output voltage. Designed for low-power applications, it accepts an input voltage range of 4.5–5.5 V. The unit complies with RoHS standards. Typical uses include small electronics, signal conditioning, and embedded systems where a stable 12 V supply is needed from a ~5 V source.

## Long description

MEAN WELL SMU02L-12 is an unregulated DC-DC single-output converter in a SIP package that provides 12 VDC at up to 0.167 A (2 W) from a 4.5–5.5 V input. The module features 1500 VDC input-to-output isolation and is designed for compact, low-power applications requiring a 12 V supply derived from a ~5 V source. The product is RoHS-compliant and intended for use in small electronics and embedded systems where space and efficiency are important.
Advantages
The converter delivers a stable 12 V output at low current draw while offering high I/O isolation of 1500 VDC in a small SIP package. Its 4.5–5.5 V input range allows direct use with standard 5 V supplies. The compact size and 2 W power rating make it suitable for space-constrained designs and low-power signal-conditioning tasks.
Suitable for
 Small electronics and handheld devices
 Embedded systems and microcontroller peripherals
 Signal conditioning and sensors
 Applications requiring isolation between input and output
