AC power inlet modules like IEC-F-1 from Adam Tech are frequently the source of some confusion here at DigiKey. These devices are rated on DigiKey’s website for a given current rating - 15A, in the case of IEC-F-1 - but upon inspection of labels or datasheets a different current rating such as 10A can be found. Why does this happen?
The different current ratings for devices like this arise from different safety certification standards testing. In the example case of IEC-F-1, the 15A rating is its UL-approved current rating; by UL standards and UL testing, the device can handle 15A. its 10A current rating comes from IEC standards and testing, which is stricter and produces only a 10A current rating for the same device. The current rating that applies for this device depends on which standard you are building to or which standard you wish to use. For average hobby use you can safely assume the 15A rating will hold, but for large production projects you’ll want to do your research and ensure you’re meeting whichever standards apply to your application.
