Power Adapter MEAN WELL SPAN02E-05 2W 5V 0.4A RoHS

The MEAN WELL SPAN02E-05 is a compact PCB-mount DC-DC converter designed for single-output 5 V at 0.4 A from a 4.5–9 V DC input. Supplied in a SIP through-hole package, this 2 W adapter meets RoHS requirements and is intended for integration into low-power electronic equipment where a stable 5 V rail is required.

Advantages

The SPAN02E-05 provides a small footprint for board-level mounting, predictable 5 V regulation at up to 0.4 A, and compliance with RoHS for reduced environmental impact. The SIP through-hole format simplifies mechanical retention and soldering on standard PCBs, while the 2 W power rating suits many low-power applications.

Suitable for

• Embedded systems and microcontroller boards requiring 5 V supply
• Low-power sensors, modules and communication peripherals
• Industrial control circuits with limited space for converters

How to use

Mount the SPAN02E-05 into the PCB using the SIP through-hole pads and solder securely. Provide a DC input within the 4.5–9 V range, observing correct polarity. Place input and output decoupling capacitors on the PCB as recommended by your design rules to improve transient response and reduce noise. Verify that the thermal environment and available PCB copper are sufficient for continuous 0.4 A output.

Recommendations

Use the converter within its specified input range and rated output current; ensure adequate PCB copper area or heat dissipation for continuous operation near the 2 W limit. Add filtering and transient protection on the input for noisy environments, and follow MEAN WELL application notes for PCB layout and grounding to ensure reliable performance.
