The the capacitors will not be overheated. The inductance thermal limits of the dielectric (85C) must be respected. of the connections must be low enough to ensure equal current sharing of capacitors in parallel. The self-heating can be calculated from the series resis- For series assemblies, connect resistor across each tance, Tg and the thermal resistance given in the table capacitor. Optimal resistance value will be: of values = P x Rth 85C - ambient R 30 M /C in F (1.5 M for C = 20 F).
