Hey guys!
I'm working on a little side-project and basically i need a compact source of a burst of electricity, so naturally the high-school physics in my head said "capacitor." Now i just don't know what kind to get! I need the maximum amount of energy to store (joules) and a quick discharge (low ESR right?). So I'm thinking Supercapacitor but there are so many capacitors and calculating .5(F)(V^2) for all of them to figure out which best suits me is daunting, so does anyone have any experience with these sorts of things and have any recommendations? Like i said, i just need it to give one high-powered burst of electricity. Also, how do you boost capacitors power? Series or Paralell? I think it's in series but I'm not 100%. Currently the two best ones i can find are the Illinois supercapacitor w/ Capacitance of 400F and Voltage of 2.7 (does this also mean discharge voltage?) w/ ESR of .003.
Size, mass and shape are of a great concern, otherwise this would be easy! I'm trying to keep size and mass on the small side and shape=cylindrical. The Illinois one is 35mm in diameter which is on the big side but it puts out energy! I also saw a Cooper Bussmann Aerogel Supercapacitor B-Series w/ C=50F, V=2.5volts, ESR=.025 and diameter of 18mm. Its not as strong as the other one but it's about half the size and almost a fourth of the mass.
Thanks for any advice you can give!
Edit:
I may have misspoken when i threw around terms like power and energy, i need a capacitor that gives off the Most Current in the shortest amount of time.
Thanks again!
