Vw: permanent working or operating DC-voltage.
HOT SPOT CALCULATION
Qhot spot = Qambient + (Pd + Pt) X Rth
with Pd (Dielectric losses) = Q x tg8o
=> [ ]4 X Cn X (Vpeak to peak)2 X f ] X (2 X 10"4)
Pt (Thermal losses) = Rs X (Irms)2 where Cn in Farad Irms in Ampere f in Hertz
V in Volt
Rs in Ohm
9 in °C
Rth in °C/W
