These bonds are capable of withstandingonly a limited amount of energy for each spike. The table shows the maximumenergy permitted in the form (I 2 .t), where I is in Ampere, and t is in seconds.Note: The formula (I 2 .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 (I 2 .t) values.Variation of capacitance with temperature ΔC ≤ ±2% between -40 and 85°CCClimatic category 40/085/56 (IEC 60068)Test voltage between terminals @ 25°C V s during 10sTest voltage between terminalsand case @ 25°C (Type test)@ 4 kVrms @ 50 Hz during 1 min.DielectricPolypropylenePROTECTIONAPPLICATION NOTESG.T.O.
