## Summary description

Mean Well SPA01B-12 is a compact power adapter/inverter with input range 18–36 V and fixed 12 V output delivering 1 W of output power. Designed for low-power applications, it complies with RoHS and weighs approximately 3 g. Typical uses include small electronic modules, signal converters, and embedded systems where a stable 12 V supply from 18–36 V sources is required.

## Long description

Mean Well SPA01B-12 is a compact DC-DC regulated single output converter designed to provide a stable 12 V output from input voltages between 18 and 36 V. Delivering 1 W (12 V at 0.083 A) in a SIP package, this adapter/inverter is intended for low-power electronic applications where a small form factor, high isolation and RoHS compliance are important. The module offers 1500 VDC input-to-output isolation and weighs approximately 3 g, making it suitable for space-constrained and lightweight designs.
Advantages
The SPA01B-12 provides regulated 12 V output with low power consumption and a compact SIP package that simplifies board-level integration. High input-to-output isolation enhances safety and reduces interference between circuits. The wide input range allows operation from various 18–36 V sources, while RoHS compliance ensures adherence to environmental standards. Its small weight and size facilitate use in embedded systems and modules with limited space.
Suitable for
Small electronic modules and signal converters
Embedded systems and controllers requiring isolated 12 V supply
Low-power instrumentation and sensor interfaces
Battery-powered or vehicle systems with 18–36 V available
Key specifications
Input voltage range: 18–36 V DC
Output voltage: 12 V DC
Output current: 0.083 A (maximum)
Output power: 1 W
Isolation voltage (input-to-output): 1500 V DC
Package type: SIP (single in-line package)
Compliance: RoHS
Approximate weight: 3 g
How to use
Install the SPA01B-12 on the circuit board in the specified SIP footprint, observing correct polarity and recommended soldering practices for small modules. Connect an appropriate 18–36 V DC source to the input pins and take the regulated 12 V from the output pins. Ensure the load does not exceed the maximum output current of 0.083 A and provide adequate spacing or mounting to respect the isolation requirements. Verify thermal conditions in the intended enclosure since the converter is intended for low-power applications.
Usage recommendations
Use the SPA01B-12 where a low-power, isolated 12 V rail is required and the load stays within the 1 W rating. For reliable operation, avoid continuous operation at the maximum output current without confirming ambient temperature and ventilation. Maintain clearance distances and proper board layout to preserve the specified input-to-output isolation.
