Hy-Cap Supercapacitor - Vinatech

These EDLC supercap have one-tenth of energy, but delivers over 10 times of power due to ultra low ESR. In Comparison with a Battery. A Lifetime of over 500,000 cycles.

Hy-Cap EDLC Single cell - Vinatech

Hy-Cap is an energy storage device that stores instantly a  large volume of electric energy and supplies instantly or  continuously higher current, by the mechanism of  absorbing and de-absorbing electric charge.

Hy-Cap Supercapacitor - Vinatech

Hy-Cap EDLC single cell models use activated carbon on the anode  and cathode electrodes. These models come in lead terminal,snap-in terminal and axial terminal variants.

Vinatech - LED Lighting, RF Solution, SoC, Discrete Devices for RF. Tantalum and EDLC capacitors.

EverCAP - Double Layer Capacitors - Nichicon

Some things to note for a design engineer. The EDLC or Electric Double Layer Capacitors ...
  • Note Specified Endurance and end of life.
  • Excess Vibration can alter Specs, Damage.
  • Caution - Never Exceed Maximum temperature.
  • Specs are very dependent on Temperature.
  • Maintain Low ripple current on Charge/Discharge.
  • It is Polarized like a Electrolytic cap.
  • No Heating Parts or Heatsink near the Cap.
