It is necessary to respect the thermal limits of the dielectric 85°C

see “Hot spot temperature calculation”

Insulation resistance

Ri x C ≥ 30,000 s

Impulse current

I2.t max. given in the tables

Spikes or peak currents in the capacitors may cause a deterioration of the

bonding between the metallization and the connections. These bonds are

capable of withstanding only a limited amount of energy for each spike. The

table shows the maximum energy permitted in the form (I2.t), where I is in

Ampere, and t is in seconds.

Note: The formula (I2.t) replaces dV/dt which is less easy to use as it is not an expression of energy (I = C.dV/dt).

This type of capacitor has been designed to withstand high (I2.t) values.
