## Summary description

Mean Well IRM-02-3.3S is a compact AC-DC power module delivering 2 W output at 3.3 V and up to 0.6 A. It accepts a wide input range of 85–305 V AC, complies with RoHS, and is suitable for embedded electronics, industrial control, and instrumentation requiring low-power regulated supply. Dimensions: 33.7 × 15 mm depth/height, weight 25.5 g.

## Long description

Mean Well IRM-02-3.3S is a compact AC-DC module designed to provide a regulated 3.3 V DC output at up to 0.6 A with a rated output power of 2 W. The module accepts a wide input voltage range from 85 to 305 V AC, is delivered in an encapsulated SMD form factor and is intended for integration into embedded electronics, industrial control systems and instrumentation where a small, reliable low-power supply is required. Its lightweight construction and small footprint support space-constrained designs.
Advantages
The IRM-02-3.3S offers a wide input voltage range allowing universal AC mains compatibility and simplifies power design across regions. Its encapsulated SMD package provides electrical insulation and mechanical protection suitable for PCB mounting. With a fixed regulated 3.3 V output and low-profile dimensions, the module reduces the need for additional regulation stages and supports compact product layouts. Compliance with RoHS ensures absence of certain hazardous substances in the component.
Suitable for
 Embedded microcontroller and single-board computer power supplies
 Industrial control modules and automation sensors
 Instrumentation, measurement devices and data acquisition front-ends
 Low-power communication modules and interface circuitry
 Compact consumer electronics and prototype PCBs

How to use
Install the IRM-02-3.3S on the target PCB following the manufacturer’s recommended land pattern and soldering profile for SMD modules. Connect the AC mains input within the specified 85–305 V AC range to the input terminals and verify correct polarity where applicable. Route the regulated 3.3 V output to the load ensuring the current draw does not exceed 0.6 A. Provide adequate spacing and, if required by the application, attach additional filtering or transient suppression components on the input or output to meet EMC or surge requirements. Observe safe handling and isolation practices when working with mains voltages.
Usage recommendations
For reliable operation, maintain the module within its rated input voltage and output current limits, ensure sufficient PCB creepage and clearance for mains isolation, and consider thermal management in enclosed designs. Add input EMI filtering and surge protection when used in electrically noisy or industrial environments. Verify the module’s performance in the final system during prototype testing to confirm stability and thermal behavior under expected load conditions.
