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-09 for a small embedded circuit that needs a 9V rail?

Yes, if the load stays within its 1W rating and 111mA output current. It provides a fixed 9V output in a 12.9 × 10.9 × 7.1 mm package, which suits low-power embedded electronics where board space is limited.

Is the SBTN01L-09 appropriate for light industrial interface or monitoring electronics?

It can be used for low-power industrial or embedded circuits that need a 9V output and remain within 1W. With 111mA available, it is better suited to small interface, monitoring, or auxiliary functions than to heavier loads.

Can the SBTN01L-09 fit in compact electronics with strict size limits?

Yes. The converter measures 12.9 × 10.9 × 7.1 mm and weighs 0.0011 kg, so it is intended for very compact assemblies. That makes it suitable where a small 9V converter is needed without using much board or enclosure space.

What input range should I pair with the SBTN01L-09?

The specified input is 4.5-5.5VDC (5V nominal). It should be selected for designs that provide a DC input within that window and need a fixed 9V output up to 111mA.

Can the SBTN01L-09 operate in harsh temperature conditions?

Its operating temperature range is -40°C to +90°C, with load derating at high ambient temperature per the derating curve. That wide range supports use in equipment exposed to significant temperature variation, provided the rest of the system is rated for the same environment.

How does the SBTN01L-09 differ from the other SBTN01L options?

The SBTN01L family members all have a 1W rating, but their outputs are different: SBTN01L-03 is 3.3V at 300mA, SBTN01L-05 is 5V at 200mA, SBTN01L-09 is 9V at 111mA, SBTN01L-12 is 12V at 84mA, and SBTN01L-15 is 15V at 67mA. The main difference is the output voltage and its corresponding current within the same 1W class.
