Surge Voltage
Surge voltage is the maximum voltage (peak value) which may be applied to the capacitor.
The surge voltage must not be applied for periodic charging and discharging in the course of normal operation and cannot
be part of the application voltage.
Surge voltage capability is demonstrated by application of 1,000cycles at relevant voltage at 105ºC and 125ºC.
The parts are charged through a 33 Ohm resistor for 30 seconds and then discharged though a 33 Ohm resistor for each
cycle.

Reverse Voltage
Polymer electrolytic capacitors are polar devices and may be permanently damaged or destroyed if connected in the wrong
polarity. These devices will withstand a small degree of transient voltage reversal for short periods as shown in the below
table.
