■
Here is an example of forced air cooling with heatsink.
■
Please consider this example as a design guideline because it changes by the heat
dissipation environment. Please measure the temperature of the actual equipment
eventually.
■
If it is difficult to measure the center of the baseplate, please measure the leeward
side of the baseplate edge.
