  1. power - How Much Current Can a Supercapacitor Reliably Supply …

    Feb 13, 2025 · Rather than using supercapacitors, it sounds to me like a good quality power management circuit can provide the motors with high current for short periods of time and then …

  2. Why is my super-capacitor self-discharging so fast?

    May 14, 2024 · Is this discharge normal? Is it possible that the capacitor is low-quality with high leakage? Do I understand this topic correctly? Did I miss any important info about super …

  3. supercapacitor - How to make a super capacitor jump starter that …

    I have been watching videos on super capacitor jump starters for cars. I figured out about 90% of how they work, but there is one last thing I don't understand. The jump starters use a boost …

  4. supercapacitor - Super capacitors derating - Electrical Engineering ...

    May 13, 2024 · I want to use supercaps in a system for minimal power interruption backup (1-2 seconds). My systems works at - 40 to 85°C. I have seen that supercaps are usually rated for …

  5. supercapacitor - Super Capacitor Charge and Discharge Circuit ...

    Nov 11, 2014 · I am working on adding a super-capacitor to one of my 5V lines. Foolishly I tried adding the super-capacitor directly to the 5V line, but it over stresses my regulator to charge it …

  6. supercapacitor - How to replace a lithium-ion battery with a super ...

    Nov 12, 2023 · Why the super-capacitor if you want to modify the electronics to ignore the absence of a battery to begin with?

  7. Supercapacitor minimum voltage - Electrical Engineering Stack …

    Mar 10, 2024 · The question doesn't contain a link to a specific datasheet for a Lithium Ion supercapacitor, but looking at the example for the CAP-XX LY13R8 RADIAL LEAD LITHIUM …

  8. supercapacitor - How to calculate how long a supercap can …

    What's the formula to calculate how many seconds a supercapacitor can provide power when employing a buck/boost converter? Also, how different would that calculation be when using a …

  9. RTC backup by super capacitor estimation issue

    Jul 1, 2020 · This is based on a 0.33 F supercapacitor. If someone got an idea for why my RTC sink 50µA instead of 300nA It's most probably the DFLS130L-7 schottky diode. Take a look at …

  10. supercapacitor - Calculating capacitor leakage current - Electrical ...

    Oct 4, 2021 · I'm trying to calculate the approximate leakage current for some capacitors I have. They are 5F 2.7v supercapacitors. I charged them up to 2.69v using a precision bench supply …
