Power adapter/inverter MEAN WELL SPA01A-12 12 V 1 W 0.083 A RoHS

MEAN WELL SPA01A-12 is a compact DC-DC regulated single output converter that delivers 12 V DC at up to 0.083 A with an output power of 1 W. Designed in an SIP package and weighing approximately 3 g, this small form-factor power adapter/inverter provides 1500 VDC input-to-output isolation and complies with RoHS requirements. It is supplied in high-quantity packaging suitable for production and integration into space-constrained and low-power electronic designs.

Advantages

The SPA01A-12 combines regulated output performance with strong isolation in a minimal footprint, allowing reliable voltage conversion for sensitive circuits. Its SIP package and light weight make it easy to mount on PCBs or into compact modules. The 1500 VDC isolation enhances safety and reduces interference between input and output circuits. RoHS compliance ensures compatibility with environmentally conscious manufacturing processes.

Suitable for

• Low-power electronics and sensor modules
• Signal conditioning and measurement devices
• Embedded systems and microcontroller peripherals
• Production assemblies requiring high-volume, compact converters

Key specifications

• Output current: 0.083 A
• Output power: 1 W
• Isolation voltage (input-to-output): 1500 V DC
• Package type: SIP (single in-line package)
• Compliance: RoHS
• Typical weight: ~3 g

How to use

Install the SPA01A-12 into the PCB following the manufacturer’s recommended footprint and soldering guidelines for SIP components. Connect the appropriate DC input voltage within the converter’s specified range and verify polarity before powering. Route input and output traces to minimize noise coupling and maintain required creepage and clearance for the isolation rating. Verify output voltage under the expected load conditions and provide any necessary filtering or decoupling at the output for the downstream circuitry.

Recommendations

For reliable operation, ensure the ambient temperature and mounting conditions match the converter’s limits and provide adequate ventilation if installed in dense assemblies. Keep high-voltage input traces separated from low-voltage output circuits to preserve the 1500 VDC isolation. When designing for production, use the standard SIP footprint and consider tape-and-reel or bulk handling methods that correspond to the supplier’s high-quantity packaging.
