  23. 23. C4AQ series DC-Link Applications Hot spot calculation Hot spot calculation: The hot spot is the internal point of the capacitor where the temperature reaches maximum value. Rth and ESR are listed in the catalogue as a function of cap and Rated Voltage In DC-Link capacitors the ESR is constant in the range 2KHz – 50KHz, We can simply consider the total Irms instead of the harmonic composition • Rth = Thermal resistance • PD = Power dissipated • ESR = Equivalent Series Resistance @ 10KHz Typical trend
