## Summary description

MEAN WELL SPAN02E-03 is a compact power adapter/inverter with 2 W output power and 0.5 A output current. Designed for low-power electronic applications, it includes RoHS compliance for reduced hazardous substances. Suitable for embedded devices, sensors, LED modules and other small equipment requiring stable low-power conversion.

## Long description

MEAN WELL SPAN02E-03 is a compact DC-DC converter designed for PCB mounting with a SIP through-hole package. It converts input voltages from 4.5–9 V DC to a regulated single 3.3 V DC output capable of supplying up to 0.5 A, with an output power of 2 W. The module is intended for low-power embedded electronics and offers RoHS compliance to limit hazardous substances.
Advantages
The module provides a stable 3.3 V output at up to 0.5 A while occupying minimal board space thanks to its SIP through-hole form factor. Its input range of 4.5–9 V DC makes it compatible with common battery and system rails. Low-profile PCB-mount design simplifies integration into control boards and sensor assemblies. RoHS compliance reduces environmental and safety concerns in end products.
Suitable for
Microcontroller boards and embedded control systems requiring 3.3 V power
Battery-powered devices and portable equipment using 4.5–9 V supplies
Sensors, small IoT nodes and telemetry modules with low current draw
LED modules, display drivers and other small electronic loads
Key specifications
Function: DC-DC converter, step-down
Input voltage range: 4.5–9 V DC
Output voltage: 3.3 V DC (single output)
Maximum output current: 0.5 A
Maximum output power: 2 W
Package type: SIP through-hole for PCB mounting
Compliance: RoHS
How to use
Mount the module on the PCB using the SIP through-hole pins and ensure correct orientation before soldering. Provide an input supply within the specified 4.5–9 V DC range and observe correct polarity. Connect the 3.3 V output to the target circuit, taking into account the 0.5 A current limit to avoid overloading. Place decoupling capacitors and follow manufacturer layout recommendations for grounding and thermal considerations to maintain output stability.
Usage recommendations
For reliable operation, keep the ambient temperature within the module’s specified operating range and allow adequate PCB copper area for heat dissipation. Avoid sustained loads near the maximum 0.5 A rating; if higher continuous current or additional margin is required, select a higher-power converter. Use proper input filtering when connecting to noisy power sources and follow standard ESD precautions during handling and assembly.
