## Summary description

MEAN WELL SPAN02A-03 is a compact power adapter/inverter with 2 W output power and 0.5 A maximum output current. Designed for low-power electronic applications, it complies with RoHS sustainability requirements. Typical uses include powering small embedded devices, sensors, and control modules where low power and a reliable DC output are required.

## Long description

MEAN WELL SPAN02A-03 is a compact DC-DC converter designed for low-power embedded electronics. The module accepts a wide input range and provides a regulated single 3.3 V DC output up to 0.5 A, delivering 2 W of output power in a SIP through-hole package suitable for PCB mounting. Compliance with RoHS indicates reduced hazardous substances in manufacturing, making it appropriate for projects where environmental standards are required.
Advantages
The SPAN02A-03 offers a small footprint and straightforward PCB integration thanks to its SIP through-hole form factor. Its wide input voltage range provides flexibility for use with different battery or supply rails between 9 and 18 V DC. The regulated 3.3 V output ensures stable voltage for sensitive microcontrollers, sensors, and communication modules while limiting power dissipation in space-constrained designs.
Suitable for
Powering small embedded systems and microcontroller boards that require 3.3 V
Sensor modules and low-power measurement instruments
Industrial control modules with limited power budgets
Battery-powered devices and prototypes operating from 9–18 V supplies
Key specifications
Topology: DC-DC converter, PCB mount
Input voltage range: 9–18 V DC
Output: single 3.3 V DC
Maximum output current: 0.5 A
Output power: 2 W
Package: SIP through-hole
Compliance: RoHS
How to use
Install the module on a PCB using the SIP through-hole pins, ensuring correct orientation of input and output terminals. Supply an input voltage within the 9–18 V DC range and verify polarity before powering the board. Route adequate traces and ground connections to minimize noise and voltage drop. Add external decoupling capacitors on the input and output if required by your application to improve transient response and stability. Observe the device's current limit and thermal conditions during operation.
Usage recommendations
For reliable operation, avoid continuous operation at the maximum current in environments with limited airflow; provide sufficient PCB copper area for heat dissipation. Confirm compatibility with downstream circuitry requiring 3.3 V logic levels and protect sensitive inputs from transients using appropriate filtering or transient suppressors.
