  1. 1.All parameters are specified at normal input, rated load, 25℃ 70% RH ambient.
  2. 2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1uf & 47uf capacitor.
  3. 3.Line regulation is measured from low line to high line at rated load.
  4. 4.Load regulation is measured from 10% to 100% rated load.
  5. 5.Please prevent the converter from operating in overload or short circuit condition for more than 30 seconds.

FAQ

Can I use the SPA01A-05 to derive 5V power inside a compact embedded board?

Yes, this DC-DC converter is designed for 5V constant voltage output with a 1W power rating. Its 17.4 × 11.1 × 7.75 mm size also suits space-constrained embedded designs.

Is the SPA01A-05 suitable for low-power industrial monitoring or control electronics?

It can be used for low-power 5V electronics when the total load fits within 1W. The input range is listed as 9-18VDC, so the source side needs to stay within that range.

Can this converter support a 5V sensor or logic stage from a 9-18VAC source?

Yes, if the application needs a 5V constant voltage output and remains within the 1W rating. It is intended for low-power conversion rather than larger 5V loads.

Is the SPA01A-05 appropriate for harsh temperature environments?

The specified operating temperature range is -40°C to +90°C, which is broader than the SP power supplies listed here. No IP rating is provided, so the specs do not establish outdoor or sealed-enclosure performance.

When is the SPA01A-05 a better fit than the SPA01A-12 or SPA01A-15?

Choose the SPA01A-05 when the required output is 5V at 1W. The listed siblings are SPA01A-12 at 1W, 12V, 0.08A and SPA01A-15 at 1W, 15V, 0.07A.
