Solid State Drives/High Energy Applications

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 1,000 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.
