Subject: Model Parameters
Message:
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

Subject: Can I automatic to cancel the default setting when I import the file?
Message:

After success to import the file, the PRISM still use "dafault" parameters to calculate failure rate. For example, I want to use the capacitance parameter "4.7 uF" of the capacitor, not the default "0.10 uF" . I need to cancel the "use default"-button one by one. Can I automatic to cancel the default setting when I import the file?
