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 SBTN01L-12 for a low-power 12V sensor or monitoring module in industrial equipment?

Yes, this model is an unregulated DC-DC converter with a fixed 12V output rated for 84mA and 1W. It fits low-power industrial or automation loads that specifically need 12V and stay within that output limit.

Is this converter a good fit for embedded control boards that need a small 12V rail from a 5V DC source?

It can be a fit when the source available to the converter is 4.5-5.5VDC and the downstream circuit needs a fixed 12V output. The output capacity is 84mA at 1W, so it is intended for light embedded loads rather than higher-current subsystems.

Can I use this for a compact automation interface circuit that only needs a small amount of 12V power?

Yes, the small size of 12.9 x 10.9 x 7.1 mm and 0.0011 kg weight make it suited to compact electronics where board space matters. Its 12V output is limited to 84mA and 1W, so it is best for low-power interface or signal-stage use.

Is the SBTN01L-12 suitable for outdoor or harsh-environment use?

The operating temperature range is -40°C to +90°C, with load derating at high ambient temperature per the derating curve, which supports use across a wide temperature span. No IP rating is listed in the provided specs, so it is better matched to protected indoor equipment or enclosed assemblies rather than exposed outdoor locations.

How does the SBTN01L-12 compare with the other SBTN01L output options?

Within the SBTN01L family, all models are 1W units. The sibling outputs are 3.3V at 300mA for the SBTN01L-03, 5V at 200mA for the SBTN01L-05, 9V at 111mA for the SBTN01L-09, and 15V at 67mA for the SBTN01L-15, while this model provides 12V at 84mA.
