Power adapter/inverter mean well SPA01B-05, input 18–36 V, output 5 V, 1 W

Mean Well SPA01B-05 is a compact DC-DC regulated single-output converter in a SIP package. It accepts an input range of 18–36 VDC and delivers a regulated 5 VDC output at up to 0.2 A (1 W). The module provides 1500 VDC input-to-output isolation, is RoHS compliant and weighs approximately 3 g, making it suitable for integration into space-constrained, low-power electronic designs and production assemblies supplied in bulk.

Advantages

The SPA01B-05 offers a small SIP form factor and high input-to-output isolation (1500 VDC), ensuring safety and noise separation in distributed electronics. Its regulated 5 V output and wide input range (18–36 V) simplify integration with various DC power sources. With a lightweight construction and RoHS compliance, it is appropriate for industrial and embedded applications requiring reliable low-power conversion.

How to use

Connect the SPA01B-05 module according to the manufacturer’s pinout in a PCB layout that accommodates a SIP package. Provide a DC source within 18–36 V to the input pins and take the regulated 5 V output from the corresponding output pins. Observe polarity and recommended PCB creepage/clearance for safe operation. Ensure the output load does not exceed 0.2 A and allow for adequate thermal conditions in confined installations.

Recommendations

Use the SPA01B-05 in applications that require galvanic isolation between input and output and limited power (1 W). For reliable performance, operate within the specified input range, keep the output current below 0.2 A, and follow PCB layout and isolation guidelines from the manufacturer. When integrating into production, consider the bulk packaging quantity.
