For the cautious, a good piece of advice is to always wait to buy a new product until after the first model year, whether its cars or consumer electronics or any other major purchase. This gives the ...

Among the abundance of components making up electronic circuits, very few are as important as capacitors. These components, taking the form of conductive plates separated by an insulating material ...

Taiyo Yuden to offer ‘lithium ion capacitors’ – devices that combine super-capacitor and lithium ion storage to create a component with twice the storage capacity of its own super-caps, a 3.8V ...

The circuit was designed to create a spare and reserve power source with the use of batteries during the absence of power from the mains. BD139 – NPN power transistor used for driver stages in hi-fi ...

Individual pieces of graphene have some pretty amazing properties, but finding a way to produce bulk materials that make good use of those properties has been rather challenging. Now, researchers have ...

The bulky batteries that power mobile devices could one day be extinct. Oki Printed Circuits has showcased technology that embeds a 170?m-thick thin-film all-solid-state lithium-ion (Li-ion) ...

ExtremeCircuits presents a small electronic switch that connects a battery to the equipment for a certain amount of time when a push-button is momentarily pressed. And we have also taken the ambient ...
