Test conditions and notes6
- 1.All parameters are specified at normal input(L:5Vdc, M:12Vdc, N:24Vdc), rated load, 25℃ 70% RH ambient.
- 2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μf & 47μf capacitor.
- 3.Line regulation is measured from low line to high line at rated load.
- 4.Load regulation is measured from 10% to 100% rated load.
- 5.Patient leakage current(2μA max.) and reinforced isolation is based on a 250VAC, 50/60Hz system input voltage.
- 6.The final equipment must be re-confirm that it still meet EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”(as available on http://www.meanwell.com)

FAQ
What is the Mean Well MDS02M-03N designed for?
The MDS02M-03N is a 2W SIP-package DC-DC converter intended for compact embedded power conversion in space-constrained equipment. This model provides a 3.3V output and is suited to B2B and industrial designs that need reinforced isolation and approved safety coverage.
What are the key electrical specifications of the MDS02M-03N?
This model is rated for 2W output power and provides a 3.3V output. The listed rated current is 28 mA, and the product is part of Mean Well's MDS-MDD SIP7 DC-DC converter family.
Is the MDS02M-03N suitable for medical or safety-sensitive equipment?
Yes. The series is described as medical safety approved to IEC60601-1 with 1xMOPP/2xMOOP coverage, and it also complies with IEC/UL62368-1 except for the 15Vo and +/-15Vo versions. It also specifies low patient leakage current below 2 uA and 6KVDC input-to-output isolation with reinforced insulation.
How does the MDS02M-03N handle harsh operating environments?
The MDS02M-03N is specified for an operating temperature range of -40C to +95C, making it appropriate for demanding industrial environments. Its compact SIP7 form factor also supports use in dense assemblies where board space is limited.
What protection features does the MDS02M-03N include?
This model includes continuous short-circuit protection for long-duration fault conditions. The series also provides overload protection that shuts down the output when rated power reaches 102% or higher, then recovers automatically.
How compact is the MDS02M-03N compared with other isolated DC-DC converter formats?
The MDS02M-03N uses a SIP7 package with dimensions of 19.7 x 7.1 x 11.5 mm and a weight of 2.8 g. Compared with larger board-mount converter formats, this makes it a compact option for applications where isolation and small size both matter.
