I am trying to understand the heatsink datasheet provided in the following link:
My problem is that the heatsink is available for lengths:
50 mm / 75 mm / 100 mm / 1000 mm
I am trying to find the thermal resistance for the 1000mm one. From the graph you can see that the thermal resistance is only given on the interval from 40-200mm. How can I find the thermal resistance for 1000mm?
If anyone know I would really appreciate the help:)
