Two adjacent conductors are sandwiched by a layer of non-conductive insulating medium to form a capacitor. When a voltage is applied between two plates of a capacitor, the capacitor stores charge. The capacitance of a capacitor is numerically equal to the ratio of the amount of charge on one conductive electrode plate to the voltage between two electrode plates. The basic unit of capacitance of a capacitor is farad (F). The capacitor element is usually represented by the letter C in the circuit diagram.
Capacitors play an important role in circuits such as tuning, bypassing, coupling, and filtering. It is used in the tuning circuit of the transistor radio, and it is also used in the coupling circuit and bypass circuit of the color TV.
With the rapid development of electronic information technology, the upgrading of digital electronic products is becoming faster and faster. The production and sales of consumer electronics products, including flat-panel TVs (LCD and PDP), notebook computers, and digital cameras, continue to increase, driving Capacitor industry grows.

ABB Capacitor Model

In a DC circuit, a capacitor is equivalent to an open circuit. A capacitor is a component that can store charge and is one of the most commonly used electronic components.
This has to start from the structure of the capacitor. The simplest capacitor is made up of pole plates at both ends and an insulating dielectric (including air) in the middle. After the current is applied, the plates are charged and a voltage (potential difference) is formed, but the entire capacitor is non-conductive due to the insulating material in the middle. However, this situation is under the premise that the critical voltage (breakdown voltage) of the capacitor is not exceeded. We know that any substance is relatively insulating. When the voltage across the substance increases to a certain extent, the substance can conduct electricity. We call this voltage the breakdown voltage. Capacitors are no exception. After a capacitor is broken down, it is no longer an insulator. However, at the middle school level, such voltages are not seen in the circuit, so they all work below the breakdown voltage and can be viewed as insulators.

However, in AC circuits, the direction of the current changes as a function of time. The capacitor charging and discharging process has time. At this time, a changing electric field is formed between the plates, and this electric field is also a function of changing with time. In fact, current is passed between capacitors in the form of an electric field.

The role of the capacitor:
● Coupling: The capacitor used in the coupling circuit is called coupling capacitor. It is widely used in resistance-capacitance coupling amplifiers and other capacitive coupling circuits to block DC and AC.
● Filter: The capacitor used in the filter circuit is called filter capacitor. This capacitor circuit is used in power supply filter and various filter circuits. The filter capacitor removes the signal in a certain frequency band from the total signal
Decoupling: The capacitor used in the decoupling circuit is called decoupling capacitor. This capacitor circuit is used in the DC voltage supply circuit of the multi-stage amplifier. The decoupling capacitor eliminates harmful low-frequency cross-links between each stage of the amplifier.
● High frequency vibration damping: The capacitor used in high frequency vibration damping circuit is called high frequency vibration damping capacitor. In the audio negative feedback amplifier, in order to suppress the high frequency self-excitation that may occur, this capacitor circuit is used to eliminate High frequency howling may occur in the amplifier.
● Resonance: The capacitor used in the LC resonance circuit is called resonance capacitance. This type of capacitor circuit is required in both LC parallel and series resonance circuits.

ABB Capacitor Model

● Bypass: The capacitor used in the bypass circuit is called the bypass capacitor. If a certain frequency band signal needs to be removed from the signal in the circuit, a bypass capacitor circuit can be used. Depending on the frequency of the removed signal, there is a full frequency domain (All AC signals) Bypass capacitor circuit and high-frequency bypass capacitor circuit.
● Neutralization: The capacitor used in the neutralization circuit is called neutralization capacitor. In radio high-frequency and intermediate-frequency amplifiers and television high-frequency amplifiers, such a neutralizing capacitor circuit is used to eliminate self-excitation.
● Timing: The capacitor used in the timing circuit is called timing capacitance. The timing capacitor circuit is used in the circuit that needs time control through capacitor charging and discharging. The capacitor plays a role in controlling the size of the time constant.
● Integration: The capacitor used in the integration circuit is called integration capacitance. In the synchronous separation circuit of potential field scanning, using this integrating capacitor circuit, the field synchronization signal can be taken out from the field composite synchronization signal.
● Differential: The capacitor used in the differential circuit is called differential capacitance. In order to get the sharp trigger signal in the trigger circuit, this differential capacitor circuit is used to get the sharp pulse trigger signal from various types of signals (mainly rectangular pulses).
● Compensation: The capacitor used in the compensation circuit is called compensation capacitor. In the bass compensation circuit of the deck, this low-frequency compensation capacitor circuit is used to enhance the low-frequency signal in the playback signal. In addition, there are high-frequency compensation capacitor Circuit.

● Boost: The capacitor used in the bootstrap circuit is called the bootstrap capacitor. The commonly used OTL power amplifier output stage circuit uses this bootstrap capacitor circuit to increase the positive half-cycle amplitude of the signal by a small amount through positive feedback.
● Frequency division: The capacitor in the frequency division circuit is called frequency division capacitor. In the speaker frequency division circuit of the speaker, the frequency division capacitor circuit is used to make the high frequency speaker work in the high frequency band, the intermediate frequency speaker works in the middle frequency band, and the low frequency The speakers work in the low frequency band.
● Load capacitance: It means the effective external capacitance that determines the resonance frequency of the load together with the quartz crystal resonator. Load capacitors commonly have standard values of 16pF, 20pF, 30pF, 50pF, and 100pF. The load capacitance can be adjusted appropriately according to the specific situation. Generally, the operating frequency of the resonator can be adjusted to the nominal value by adjusting.

Capacitors are widely used in various high and low frequency circuits and power circuits. They are decoupling (referring to the method of eliminating or mitigating the mutual influence between two or more circuits in some way), coupling (connecting two or more circuits Methods of making them interact with each other) filtering (removing interference signals, clutter, etc.), bypassing (parallel with a component or a circuit, one of which is grounded), resonance (referring to parallel or series connection with an inductor, The oscillation frequency is the same as the input frequency. For example, the tuning selects the radio frequency), step-down, and timing.

The capacitor has the characteristics of “passing AC and blocking DC”. The polarity and voltage of the direct current are fixed and cannot pass through the capacitor. The polarity of the alternating current and the magnitude of the voltage are constantly changing, which can continuously charge and discharge the capacitor to form a charge and discharge current.
