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 course of normal operation and cannot be part of the application voltage.
Surge voltage capability is demonstrated by application of 1,000 cycles at operating temperature. 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.
