Power adapter MEAN WELL SPU01L-12 1 W Input 4.5-5.5 V Output 12 V

The MEAN WELL SPU01L-12 is a compact DC-DC converter in a SIP through-hole package that accepts an input voltage from 4.5 to 5.5 V and provides a single isolated 12 V output at up to 0.084 A (1 W). The module is RoHS compliant and intended for PCB mounting where a small, reliable power adapter is required.

Advantages

The SPU01L-12 offers a small footprint for easy PCB integration, single-output 12 V regulation from low-voltage sources, and industry-standard through-hole SIP packaging for secure mechanical mounting. Its 1 W power rating suits low-power applications and the RoHS compliance meets environmental and safety requirements.

Suitable for

• Embedded systems and microcontroller boards requiring isolated 12 V supply
• Sensor modules and small peripherals powered from 5 V rails
• Prototypes and PCB-mounted devices with limited space

How to use

Mount the SPU01L-12 into the PCB using the SIP through-hole pins and solder according to standard PCB assembly practices. Supply the module with a stable 4.5–5.5 V DC source on the input pins and take the regulated 12 V output from the designated output pins. Observe correct polarity and ensure the PCB layout provides appropriate creepage and clearance for the module.

Recommendations

Use the converter within its rated input and output limits, provide adequate decoupling capacitors on the PCB if required by your design, and avoid operating continuously at the maximum rated current without verifying thermal conditions on your board.
