Test conditions and notes6

1.All parameters are specified at normal input(K:3.3Vdc, 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.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)
6.An external input filter capacitor is required if the module has to meet BS EN/EN61000-4-4, BS EN/EN61000-4-5. The filter capacitor Power Mate suggest: 220uF/100V.

FAQ

Can I use the SBTN01M-12 for a low-power 12V control or monitoring circuit in automation equipment?

Yes, this model delivers a fixed 12V output rated for 84mA with 1W total power. It is appropriate for light-duty control, monitoring, or interface circuits that require 12V and stay within that output limit.

Is this converter suitable for embedded designs that need a small 12V rail from a 12V DC source?

It is designed for a 10.8-13.2VDC input and provides an isolated, unregulated 12V output. The available output is 84mA at 1W, so it fits small embedded or industrial electronics rather than higher-current 12V loads.

Can the SBTN01M-12 fit into dense PCB layouts or compact electronic assemblies?

Yes, the package is only 12.9 x 10.9 x 7.1 mm and the listed weight is 0.0011 kg. That makes it a practical choice for compact assemblies where a low-power 12V output is needed.

Is the SBTN01M-12 intended for protected equipment rather than direct outdoor exposure?

Its operating temperature range is -40°C to +90°C, with load derating at high ambient temperature per the derating curve, so it can support equipment used across a broad thermal range. Since no IP rating is listed in the provided specs, it is better matched to indoor systems or protected enclosures than exposed outdoor environments.

How does this model differ from the other SBTN01M converter outputs?

All SBTN01M versions are rated at 1W, but the output voltage and current vary by model. The sibling outputs are 3.3V at 300mA for the SBTN01M-03, 5V at 200mA for the SBTN01M-05, 9V at 111mA for the SBTN01M-09, and 15V at 67mA for the SBTN01M-15, while this unit provides 12V at 84mA.
