Experimental electrical double-layer capacitances of porous carbon electrodes fall below ideal values, thus limiting the practical energy densities of carbon-based electrical double-layer capacitors.

In today's world of increasing electrical noise, higher-speed logic, and more-sensitive circuits, the need for high-frequency noise filtering is especially critical. Noise can enter a circuit through ...

The gradient of this graph is equal to the capacitance of the capacitor. \(C= \frac{Q}{V}\) And the area under the graph is the energy stored by the capacitor.

DLI’s V Series, single layer ceramic capacitor series has been designed to provide higher capacitance in a smaller footprint at high frequency compared with multi-layer (MLCC) types. They are ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

If a larger value of resistance were used with the same value of capacitance in the above circuit, then a smaller current would flow, therefore it would take longer for the capacitor to charge up and ...

Announced by Syfer Technology is a range of high Q low ESR capacitors designed specifically for high frequency applications. The ceramic capacitors are available in two device sizes: 0505 and 1111, in ...

Bypass capacitors are everywhere in power distribution networks. If you think in the time domain, you may say that bypass capacitors store and supply charge on demand to the loads. If you think ...

If you’ve seen a big air-variable capacitor, you may have noticed that some of the plates may have slots cut into them. Why? [Mr Carlson] has the answer in the video below. The short answer: ...
