The Art of Rebuilding Tube Amplifiers
The audio coupling capacitor is everything in a tube amplifier. ... The old style often had damping material inside to hold the plate windings in place too, which helps to absorb the delayed resonances from the winding core. Of course, where possible, use inductors and film capacitors instead, that sounds enormously better than any old or new ...

What is a Capacitor? Definition, Uses & Formulas | Arrow
Capacitance is the ability of an object to store an electrical charge. While these devices'' physical constructions vary, capacitors involve a pair of conductive plates separated by a dielectric material. This material allows each plate to hold an equal and opposite charge. This stored charge can then release as needed into an electrical circuit.

As you likely know, capacitors are used in electronic circuits to provide local energy storage and stabilize power supply voltage. Decoupling capacitors are a specific type of capacitor used to isolate or …
Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.
Capacitive coupling
OverviewUse in analog circuitsUse in digital circuitsGimmick loopParasitic capacitive couplingSee alsoExternal links
In analog circuits, a coupling capacitor is used to connect two circuits such that only the AC signal from the first circuit can pass through to the next while DC is blocked. This technique helps to isolate the DC bias settings of the two coupled circuits. Capacitive coupling is also known as AC coupling and the capacitor used for the purpose is also known as a DC-blocking capacitor. A coupling capacitor''s ability to prevent a DC load from interfering with an AC source is particul…

Choosing the correct coupling capacitor | GroupDIY Audio Forum
The higher the capacitor value, the more material in the signal path. The more material in the signal path, well, you know where this is going... the less transparent the signal becomes. When it comes to output coupling caps, less is more, as long as you''ve achieved a reasonable -3db point.
Addressing Coupling Capacitance in Designs
To examine how the input coupling capacitance will affect signal behavior and possibly lead to distortion, the value of the capacitor is defined as a global parameter CAP2. This is defined by opening the component properties dialog and setting the component value to {CAP2}.

Figure 1. ADP2441 switching regulator with the bypass capacitor C BYP at the input.. Because the input capacitor in a buck converter is part of the critical paths (hot loops) for this topology, C BYP has to be connected with as little parasitic inductance as possible. Thus, the placement of this component is important.
Why Do Capacitors Explode?
Heat causes the dielectric material inside the capacitor to degrade, leading to a decrease in capacitance and overall performance. Additionally, the expansion and contraction of materials due to temperature variations can cause mechanical stress, leading to the development of cracks or leaks in the capacitor''s structure.
