TDK Electric double-layer capacitors (EDLC) developed as power supplies for LED flashes and used on mobile phones with cameras. Resistance is low so high current can flow into the LED to obtain the same light intensity as that from a xenon lamp. Also, the capacitors are compact, thin, and lightweight, making them ideal for use in mobile phones. 350 millifarad at 5.5 volts max. Usable in applications that need a high capacitance in a thin package. The part is 0.8mm in thickness, less than the thickness of a penny. Recommended uses are smartphones, energy harvesting, camera applications, and tablet computers. The electric double layer capacitor (EDLC) employs a double layer of charged particles formed on activated carbon electrodes in an electrolyte. High capacitance is achieved due to the large electrode surface area.
