Ametherm SL22 5R012 would have been the correct selection if the ambient temperature was at 25ºC. Rated: 5 Ohms @ 25ºC, 100 Joules, 12 A Maximum Steady State Current, UL Recognized (UL File #: E209153), CSA Recognized (CSA File #: CA110861), and RoHS compliant. De-rating of steady state current is not necessary since operating temperature range is not below 0ºC and above 65ºC (Figure 1 on earlier slide).
