  1. I would have liked to see the capacitors discharged before they were charged. If they discharge at different rates, do they charge at the same rates?

  2. In order to have the same voltage rating as the 25000uF cap, you’d need to place 8 of the super caps in series. This would divide the capacitance down to 125000uF, which is still an extremely good energy density. However, you’d also need to consider ESR and ripple current ratings etc. It’s a game of tradeoffs, but supercaps are a phenomenal product. Regular bulky electrolytics still have their place though.

  3. Onde o senhor encontra esses super capacitores
    ????
    O.menor ficou 17 segundos ligado
    Ja o maior ficou apenas 000,2 milesemos de segundo.

    Isso aconteceu. Por que o voce pos o maior na bateria apenas 2 segundos e ja o menor pos 5 segundo. Por isso o menor ficou 17 segundo,

  4. A 1000mF 40v super capacitor should be 8 times larger than the 1000mF 5v super capacitor and could be smaller or the same size as the common 25mF 40v capacitor shown.

    Many people say in the comments that size doesn’t matter… But it does matter if you have to respect the voltage needs of the circuit and still evaluate the possibility of spikes considering 100% of the safety factor. I always put capacitors with twice the circuit voltage.

  5. Такие банки на трехфазных движках у китайцев стоят, не новых естественно.

  6. Большой конденсатор рассчитан на 25000 пикофарад, что около в 40 раз меньше чем у маленького конденсатора рассчитанного на целый фарад. Но в тоже время большой конденсатор может работать под напряжением до 40 вольт, ну а в свою очередь маленький всего до 5 вольт. Вот такая физика

  7. Elektrolyt Kondensator 0,025 Farad, Spanungsfestigkeit 40 Volt.
    Superkondensator 1 Farad, Spanungsfestigkeit 5 Volt.
    40 Volt/5 Volt = 8
    1 Farad/0,025 Farad = 40
    Duracell-Batterie 4,5 Volt
