FAQ

Can I use the SMU01L-12 to power a small 12V control or sensing circuit from a near-5V source?

Yes, it is suited to low-power 12V control or sensing sections that need constant voltage output within the converter's 1W rating. The output is specified as 12V at 0.08A.

Is the SMU01L-12 appropriate for embedded electronics that need 12V from a 4.5~5.5V input range?

This model is intended for applications where the input is within 4.5~5.5V and the required output is 12V constant voltage. It is designed for low-power use, with a total power rating of 1W.

Can the SMU01L-12 fit compact industrial or IT hardware with limited PCB space?

It can be a good fit in compact hardware because the body measures 11.6 × 10.14 × 6.1 mm and weighs 0.0013 kg. Those dimensions support use in small embedded or control assemblies where only a light 12V rail is needed.

Is the SMU01L-12 suitable for outdoor or high-temperature environments?

The operating temperature range is -40°C to +90°C, so the temperature spec is broad enough for demanding equipment conditions. The product data provided does not list an IP rating, so direct outdoor, wet, or dust-exposed suitability is not specified.

How does the SMU01L-12 compare with the other SMU01L family members?

The listed SMU01L series options are all 1W converters. The siblings shown are SMU01L-05 at 5V and 200A, SMU01L-09 at 9V and 110A, SMU01L-12 at 12V and 0.08A, and SMU01L-15 at 15V and 0.07A.
