Frequently Asked Questions
Can I use the SFTN01L-09 to generate a 9V rail for a low-power embedded control board from a 4.5~5.5V source?
Yes, this model is a constant-voltage DC-DC converter with 4.5~5.5V input and 9V output. Its power rating is 1W, so it fits low-power embedded or control circuits that need a regulated 9V rail rather than higher-power loads.
Is this converter suitable for a compact industrial sensor interface that needs 9V output?
It can be appropriate for a low-power sensor or interface stage when the available source is in the 4.5~5.5V input range and the required output is 9V constant voltage. The compact 15.24 × 10.9 × 7.1 mm body also fits dense industrial or embedded layouts.
Can I use the SFTN01L-09 in portable test or handheld embedded equipment?
This converter is sized for low-power applications because it is rated at 1W and weighs 0.0012 kg. That makes it a practical option for compact embedded or portable electronics that need 9V output from a 4.5~5.5V input source.
Is the SFTN01L-09 appropriate for outdoor or harsh-temperature use?
The listed operating temperature is -40°C to +90°C, which supports a wide temperature range. However, no IP rating or enclosure protection is listed, so the product data does not identify it as suitable for direct outdoor exposure.
How does the SFTN01L-09 compare with the other SFTN01L models?
Within the SFTN01L series, all listed models are 1W converters in the same family, but they differ by output rating. The SFTN01L-05 is 5V and 200A, the SFTN01L-09 is 9V and 111A, the SFTN01L-12 is 12V and 0.08A, and the SFTN01L-15 is 15V and 0.07A.
