電容類型要根據介質的種類來分，可分為無機介質電容器、有機介質電容器和電解電容器三大類。不同介質的電容，在結構、成本、特性、用途方面都大不相同。接下來，電解電容廠家為大家介紹電容的9大主要用途：

　　The types of capacitors can be divided into three categories: inorganic dielectric capacitors, organic dielectric capacitors and electrolytic capacitors. The capacitance of different dielectric is very different in structure, cost, characteristic and application. Next, the manufacturers of electrolytic capacitors will introduce the 9 main uses of capacitors

　　1.隔直流：

　　1. DC isolation:

　　作用是阻止直流通過而讓交流通過。

　　The function is to prevent the direct current from passing through and let the alternating current pass through.

　　2.旁路（去耦）：

　　2. Bypass (decoupling)

　　為交流電路中某些并聯的元件提供低阻抗通路。

　　It provides a low impedance path for some parallel components in an AC circuit.

　　3.耦合：

　　3. Coupling:

　　作為兩個電路之間的連接，允許交流信號通過并傳輸到下一級電路

　　As a connection between two circuits, it allows the AC signal to pass through and transmit to the next level circuit

　　4.濾波：

　　4. Filtering:

　　這個對DIY而言很重要，顯卡上的電容基本都是這個作用。

　　This is very important for DIY, the capacitance on the graphics card is basically this function.

　　5.溫度補償：

　　5. Temperature compensation:

　　針對其它元件對溫度的適應性不夠帶來的影響，而進行補償，改善電路的穩定性。

　　In order to improve the stability of the circuit, compensation is made to improve the stability of the circuit.

　　6.計時：

　　6. Timing:

　　電容器與電阻器配合使用，確定電路的時間常數。

　　The capacitor and resistor are used together to determine the time constant of the circuit.

　　7.調諧：

　　7. Tuning:

　　對與頻率相關的電路進行系統調諧，比如手機、收音機、電視機。

　　System tuning of frequency related circuits, such as mobile phones, radios, and TVs.

　　8.整流：

　　8. Rectification:

　　在預定的時間開或者關半閉導體開關元件。

　　Turn on or off the semi closed conductor switching element at a predetermined time.

　　9.儲能：

　　9. Energy storage:

　　儲存電能，用于必須要的時候釋放。例如相機閃光燈，加熱設備等等。如今某些電容的儲能水平已經接近鋰電池的水準，一個電容儲存的電能可以供一個手機使用一天。

　　Store electrical energy for release when necessary. For example, camera flash, heating equipment and so on. Today, the energy storage level of some capacitors is close to that of lithium batteries, and the energy stored in one capacitor can be used for a mobile phone for a day.
