FAQ

Can I use the SUS01L-09 to create a regulated 9V rail inside a compact embedded controller?

Yes, this model is a constant-voltage DC-DC converter with a 9V output and 1W power rating. Its 22.6 × 9.9 × 8.9 mm size also suits tight embedded designs that have a 4.5~5.5V input available.

Is the SUS01L-09 suitable for low-power industrial sensor or interface boards that need 9V from a 4.5~5.5V source?

It can fit low-power industrial electronics that need a fixed 9V output, as long as the total load stays within the 1W rating. The converter is designed for 4.5~5.5V input and constant-voltage operation.

Can this converter be used in portable test, monitoring, or automation electronics that need a small 9V supply stage?

It is appropriate for compact low-power electronics where a stable 9V rail is needed and the system input falls within 4.5~5.5V. The small 0.0031 kg weight and miniature package help where board space and mass are limited.

How do I know if the SUS01L-09 is sized correctly for my 9V circuit?

Match it to a load that needs constant 9V and does not exceed the product's 1W rating or listed 111mA output current. If your circuit needs more than this converter can deliver, you should move to a higher-power option.

Is the SUS01L-09 better for indoor or outdoor equipment?

The listed environmental spec is an operating temperature range of -25°C to +71°C, but no IP rating is provided. That makes it a better fit for protected indoor equipment or enclosed assemblies rather than direct outdoor exposure.
