2 Installation Precautions(1) Do Not Use The Capacitor That Has Been Energized On The Device. Except For Capacitors That Are Removed For Periodic Inspection During Electrical Inspection, They Cannot Be Used Again.(2) Even If The Capacitor Is Discharged, A Voltage (Re-Flash Voltage) May Be Generated Between The Terminals. In This Case, Discharge Through A 1kΩ Resistor.(3) The Leakage Current Of Capacitors Stored For More Than Half A Year May Increase. In This Case, Perform Voltage Processing With A 1kΩ Resistor.(4) After Confirming The Rated Value (Electrostatic Capacity And Voltage) Of The Capacitor, Install It.(5) After Confirming The Polarity Of The Capacitor, Install It.(6) Do Not Drop The Capacitor To The Ground. Do Not Use A Capacitor That Has Fallen Behind.(7) Do Not Deform The Capac...

THE GIST- A new super capacitor inspired by the onion has been developed by scientists.- Super capacitors are currently used to power small devices such as toys.- The new tech could provide enough energy to power a cell phone for weeks or a laptop battery for days.  Drawing on the layered design of tear-inducing onions, scientists have created a new super capacitor that is powerful enough -- and cheap enough -- to replace the larger, heavier capacitors used in consumer electronics such as computers and cells phones.  If commercialized, the new super capacitor could be fully charged i...

Oct. 21, 2015, was the day that Doc Brown and Marty McFly landed in the future in their DeLorean, with time travel made possible by a "flux capacitor."  While the flux capacitor still conjures sci-fi images, capacitors are now key components of portable electronics, computing systems, and electric vehicles.  In contrast to batteries, which offer high storage capacity but slow delivery of energy, capacitors provide fast delivery but poor storage capacity.  A great deal of effort has been devoted to improving this feature -- known as energy density -- of dielectric capac...

Electrolytic capacitors are also very common and are found in the quintessential “can” body. These capacitors are constructed from a piece of paper soaked in electrolyte sandwiched between two pieces of aluminum foil. One piece of foil, the anode, has a coating of aluminum oxide. This coating acts as the dielectric between the two electrodes. The electrolytic paper is electrically conductive, but has chemical properties that allows it to heal the oxide layer should it become damaged. The combination of aluminum oxide dielectric and electrolytes allow for very high capacitance values in a small...

Super capacitor breakthrough to boost power of electric cars  Researchers at the Queensland University of Technology have developed lightweight supercapacitors that can dramatically boost the power of electric cars.The supercapacitors, which are a sandwich of electrolyte between two all-carbon electrodes, were made into a thin and extremely strong film with a high power capacity. This film could be embedded in a course body panels, roof, doors, bonnet and floor, giving it enough area to store energy that can turbocharge an electric cars battery just a few minutes.According to the research...

WHYALUMINUM POLYMER CAPACITORS ROCK?For many decades the standard aluminum capacitorelement consisted of an anode and cathode foil with interleaved paper; analuminum oxide layer, formed on the anode, acted as the dielectric. Thiselement was wound and then impregnated with a "wet" liquid or gelelectrolyte, the purpose of which was the extend the achievable capacitanceranges.While this basic construction technique still remainsthe most popular today, it possesses several limitations; the wet electrolyteof a conventional aluminum electrolytic capacitor exhibits high (and, inapplica...

In capacitor research, much effort has beenfocused on development of high energy density devices. It’s easy to see why.The need for efficient, high-performance materials for electrical energystorage has been growing in parallel with the ever-increasing demand forelectrical energy in mobile applications. Along the way dielectric capacitors,which comprise an insulating material sandwiched between two conducting metalplates, have become key components of portable electronics, computing systemsand electric vehicles. One hurdle preventing even faster growth is that incontrast to batteries, which of...

More And more consumers these days seem to have some sort of home theater set up in which they incorporate a computer. Many people use a PC in their living room to watch slideshows of their photos, browse the web on their large HDTV displays, or use their pc as a fully functional Home Theater PC for movies, games, music, And etc. Along with this growing trend, the concept of using a HTPC style case for your living room computer is becoming more popular. People don't want some big ugly tower sitting in the middle of their living room, but would rather have a stylish looking case that can ma...
