Supercapacitors with very high capacitance values and low voltages are the bridge between the capacitors and the batteries. They are mainly used as back-up devices for the power shut-down of microcomputers and RAMs, smart meters, POE network devices, alarm systems, etc.
In this webinar, KEMET’s Roya Nikjoo (Field Application Engineer, Europe Nordic)...
Calculating the operational life of capacitors seems like an easy task, but care must be taken when calculating their lifetime. How life is calculated depends on the operating conditions and the device type.
In this live webinar, Jekaterina Stael von Holstein, Field Application Engineer at KEMET, presents the methodologies for calculating life...
Supercapacitors usually operate at low voltages of around 2.7 V. In order to reach higher operating voltages, it is necessary to build a cascade of serial connected SC cells. Due to production or ageing-related variations in capacitance and insulation resistance, the voltage drop over individual capacitors may exceed the rated...
