Film capacitor

Film/foil capacitors or metal foil capacitors are made with two plastic films as the dielectric. Each is layered with a thin metal foil, usually aluminum, as the electrodes. Advantages of this construction type are easy electrical connection to the metal foil electrodes, and its ability to handle high current surges.

They''re ideal for resonant circuit applications, like timing circuits where stability is key.

Lithium-ion capacitor

Nominal cell voltage. 1.5–4.5 V [1] A lithium-ion capacitor ( LIC or LiC) is a hybrid type of capacitor classified as a type of supercapacitor. It is called a hybrid because the anode is the same as those used in lithium-ion batteries and the cathode is the same as those used in supercapacitors. Activated carbon is typically used as the cathode.

Variable capacitor

Rotary variable capacitor Rotary variable capacitor: several rotor positions. A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning …

Aluminum electrolytic capacitor

Aluminum electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of aluminum oxide by anodization that acts as the dielectric of the capacitor. A non-solid electrolyte covers the rough surface of the ...

Frequency compensation

Explanation Figure 1: Step response of a two-pole amplifier for various degrees of compensation. Parameter ζ is set by a compensation capacitor: smaller ζ results in faster response, but more ringing and overshoot. Most amplifiers use negative feedback to trade gain for other desirable properties, such as decreased distortion, improved noise …

Niobium capacitor

A niobium electrolytic capacitor (historically also Columbium capacitor [1] [2]) is an electrolytic capacitor whose anode (+) is made of passivated niobium metal or niobium monoxide, on which an insulating niobium pentoxide layer acts as a dielectric. A solid electrolyte on the surface of the oxide layer serves as the capacitor''s cathode (−).

Capacitor

Capacitor. A capacitor (also called condenser, which is the older term) is an electronic device that stores electric energy. It is similar to a battery, but can be smaller, lightweight and a capacitor charges or discharges much quicker. Capacitors are used in many electronic devices today, and can be made out of many different types of material.

Decoupling capacitor

The decoupling capacitor works as the device''s local energy storage. The capacitor is placed between the power line and the ground to the circuit the current is to be provided. According to the capacitor current–voltage relation. a voltage drop between a power line and the ground results in a current drawn out from the capacitor to the circuit.

8.2: Capacitors and Capacitance

V = Ed = σd ϵ0 = Qd ϵ0A. Therefore Equation 8.2.1 gives the capacitance of a parallel-plate capacitor as. C = Q V = Q Qd / ϵ0A = ϵ0A d. Notice from this equation that capacitance is a function only of the geometry and what material fills the space between the plates (in this case, vacuum) of this capacitor.
