◆ RTED RIPPLE CURRENT MUIERS

The ripple frequency and standard list of the specified value is not at the same time, please use the value is less than the following

● Frequency Multipliers

Frequency(HZ) 50 120 300 1K 3K
coefficient 0.8 1.0 1.1 1.3 1.4

Note : The endurance of capacitors is shorted with internal heating produced by ripple current at the rate of halving the lifetime with every 5 to 10℃ rise. When long life performance is required in actual use, the rms ripple current has to be reduced. Also, for the LB series capacitors, using them at operating voltage less than their rated voltage can extend their lifetime. For the details, please contact representative of capsun
