Mean Well DPU01L-05 DC-DC Converter - 1W - 4.4~5.5V in ±5V out

This converter is intended for very low-power applications, with a 1W rating and constant-voltage output. Its small 19.6 × 10.2 × 7.1 mm size also suits dense embedded designs where board space is limited.

Yes, it fits low-power electronic subcircuits because it is a 1W constant-voltage converter in a very compact package. The 4-5VAC input specification makes it relevant where the source is in that input range.

It is well suited to extreme-temperature electronics because its operating range is -55°C to +125°C. That is broader than many general-purpose converters and makes it relevant for demanding industrial or embedded environments.

Yes, the DPU01L-05 is physically small at 19.6 × 10.2 × 7.1 mm and weighs 0.0027 kg, which helps in compact modules. Its 1W rating means it is best matched to low-power converter roles rather than larger loads.

All three are 1W models with the same 19.6 × 10.2 × 7.1 mm dimensions. The DPU01L-05 is listed as 5V output and 100A, the DPU01L-12 is 12V and 0.04A, and the DPU01L-15 is 15V and 0.03A.

The operating temperature range is -55°C to +125°C, which supports use in very hot or very cold environments. No IP rating is provided in the specs, so exposed outdoor suitability is not established by the listed product data.
