Subject: Model Parameters
Under "Item Properties" it is possible to select different Temperature Calculation models. The model "use ambient temperature + actual temperature rise" allows the input of a temperature rise value. Is this temperature rise supposed to be junction temperature rise or case temperature rise? Furthermore the model "use case temperature + theta jc * p" allows the input of a case temperature value. Does it mean the absolute case temperature or only the delta (relative) case temperature when compared to the chosen "op temp" temperature. Best regards, Thomas Urbanczyk
