Nominal DC voltage in clear In the case where the series diodes are screwed to the RMS current in clear capacitor, cooling of the diodes must be taken in account. Date of manufacture (IEC coding) Do not use the capacitor as a heat sink.

These bonds are capable of withstanding only a limited amount of energy for each spike. The 2 table shows the maximum energy permitted in the form (I .t), where I is in Ampere, and t is in seconds. 2 Note: The formula (I .t) replaces dV/dt which is less easy to use as it is not an expression of energy (I = C.dV/dt). 2 This type of capacitor has been designed to withstand high (I .t) values.
