When using accelerometers with long cables, you must be careful that the cables do not attenuate the signals at high frequencies. Engineers at PCB Piezotronics point out that such attenuation may ...

At audio frequencies capacitance is not a factor at all for the cables your describe. These values are miniscule and are totally swamped by the input impedance of the audio amplifier.

High-quality, low-capacitance data cables have impedances specific for RS-232/422 and RS-485 communication applications. High-quality, low-capacitance data cables have impedances specific for ...

Note: This article was originally published September 23rd, 2005 but we felt it was time for a little update based on some of the new products that surfaced to allegedly fix a non-existant problem.

In some applications it is necessary to transmit square waves across a long cable. However, long cables typically have high capacitance, which can significantly affect the signal’s wave shape. As such ...

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.
