Choosing a suitable Capacitor for High Voltage and/or High Power applications
 By capacitor functions, as different capacitor function needs different electrical and mechanical parameters.
 Voltage : AC, DC, DC+AC, Pulse Voltage (Peak + Reversal range), with different voltage profile and frequency combination, the capacitor will have a very different current requirement.
 Capacitance
 The Capacitor Current :
i. RMS Current Irms
ii. Pulse / Peak / Peak + Reversal discharge Current
iii. dv/dt  Both Reversal Current and Voltage have to take into account.
 Capacitor Ambient Temperature, Capacitor Connection, Capacitor Installation and Capacitor size.
