電解電容和瓷片電容的定義如下：

　　The definitions of electrolytic capacitor and ceramic chip capacitor are as follows:

　　瓷片電容(如圖一)是一種用陶瓷材料為介質，在陶瓷表面涂覆一層金屬薄膜，再經高溫燒結后作為電極而成的電容器。通常用于高穩(wěn)定振蕩回路中，作為回路、旁路電容器及墊整電容器。

　　Porcelain chip capacitor (as shown in Figure 1) is a capacitor made of ceramic materials as the medium, coated with a layer of metal film on the ceramic surface, and then sintered at high temperature as the electrode. It is usually used in high stability oscillation circuit as circuit, bypass capacitor and padding capacitor.

　　電解電容(如圖二)是電容的一種，金屬箔為正極(鋁或鉭)，與正極緊貼金屬的氧化膜(氧化鋁或五氧化二鉭)是電介質，陰極由導電材料、電解質(電解質可以是液體或固體)和其他材料共同組成，因電解質是陰極的主要部分，電解電容因此而得名。同時電解電容正負不可接錯。

　　Electrolytic capacitor (as shown in Figure 2) is a kind of capacitor. The metal foil is the positive pole (aluminum or tantalum). The oxide film (aluminum oxide or tantalum pentoxide) that is close to the metal with the positive pole is the dielectric. The cathode is composed of conductive materials, electrolyte (electrolyte can be liquid or solid) and other materials. Since the electrolyte is the main part of the cathode, the electrolytic capacitor gets its name. At the same time, the positive and negative of the electrolytic capacitor must not be connected incorrectly.

　　電解電容與瓷片電容的構造和特性有很大的不同!前者是有極大容量低頻特性!后者是無極小容量高頻特性!

　　The structure and characteristics of electrolytic capacitor and ceramic chip capacitor are very different! The former has great capacity and low frequency characteristics! The latter is high frequency characteristic without minimum capacity!

　　電解電容多用在藕合,濾波,退藕,等音頻及低通電路!容量多為幾微微法到0.1微法!

　　Electrolytic capacitors are mostly used in coupling, filtering, decoupling, audio and low-pass circuits! The capacity ranges from a few microf to 0.1 microf!

　　瓷片電容用在振蕩,選頻,藕合,反饋等高頻和特高頻電路!瓷片電容的高頻特性很好!穩(wěn)定性也很好!是高頻電路里的最常用電容!容量多為0.5微法到幾千至上萬微法!

　　Ceramic capacitors are used in high-frequency and ultra-high frequency circuits such as oscillation, frequency selection, coupling, feedback, etc! High frequency characteristics of ceramic chip capacitor are very good! Very stable! It is the most commonly used capacitor in high-frequency circuit! The capacity ranges from 0.5 microf to thousands to tens of thousands of microf!

　　電解電容與瓷片電容兩者差異：

　　Difference between electrolytic capacitor and ceramic chip capacitor:

　　電解電容容量大，有極性，等效串聯電感大；瓷片電容容量小，無極性，等效串聯電感小。

　　The electrolytic capacitor has large capacity, polarity and large equivalent series inductance; Ceramic chip has small capacitance, no polarity and small equivalent series inductance.

　　電解電容低頻特性好，多用于低頻電路；瓷片電容高頻特性好，多用于高頻電路。

　　Electrolytic capacitors have good low-frequency characteristics and are mostly used in low-frequency circuits; Porcelain chip capacitors have good high-frequency characteristics and are mostly used in high-frequency circuits.

　　電解電容能濾除低頻紋波，故可用作低通濾波；瓷片電容可濾除高頻紋波，故可用作高通濾波。

　　Electrolytic capacitor can filter low-frequency ripple, so it can be used as low-pass filter; Ceramic chip capacitor can filter high-frequency ripple, so it can be used as high pass filter.

　　電解電容不能用于純交流電源電路；瓷片電容可用于純交流電路。

　　Electrolytic capacitors cannot be used in pure AC power circuits; Ceramic chip capacitors can be used in pure AC circuits.
