As technology changes and adapts, so does Adafruit! Rather than the regular USB A, this cable has USB C to USB C plugs! USB C is the latest industry-standard connector…
Welcome to the forum. That’s not info I can find or test unfortunately. I think that whatever the operating limits of whatever this will be plugged into should be used for instead for your max temp.
The USB cables carry nominal 20 Vdc voltage ratings, 1 to 3 A current ratings, and an operating temperature range from –20° to 80°C. All models further comply with RoHS and the UL94V-0 flammability rating.
