Double-layer capacitor caps

Individual capacitor capsules for low voltages

Double-layer capacitors are available for voltages up to 3 V and with capacities of up to 3,400 V. If higher voltages are needed, capacitors are connected in series. In doing so, it must observed that the overall capacity in the circuit is reduced by the number of capacitors connected in series – 2 capacitors in series = double the dielectric strength, half the capacity; 3 capacitors in series = triple the dielectric strength, capacity reduced three fold. Any voltage and capacity levels can be achieved by connecting several series circuits in parallel. If capacitors are connected in series, it must be ensured that all capacitors carry the same current. In the simplest case, this is achieved with balanced resistors; power loss-optimized solutions require somewhat complex circuits. Anyone who wishes to forgo the risk, effort, time and costs required for own development can acquire customized and ready-made modules from LSMtron.
