jb Summary of Capacitor Types

The table below gives and overview of the main characteristics of the various types of capacitor.

Capacitor types Capacitance range Accuracy Temperature stability Leakage Comments
Electrolytic 0.1 µF - ~1 F V poor V poor Poor Polarised capacitor - widely used in power supplies for smoothing, and bypass where accuracy, etc is not required.
Ceramic 10 pF - 1 µF Variable Variable Average Exact performanceof capacitor depends to a large extent on the ceramic used.
Tantalum 0.1 µF - 500 µF Poor Poor Poor Polarised capacitor - very high capacitance density.
Silver mica 1 pF - 3000 pF Good Good Good Rather expensive and large - not widely used these days except when small value accurate capacitors are needed.
Polyester (Mylar) 0.001 µF - 50 µF Good Poor Good Inexpensive, and popular for non-demanding applications.
Polystyrene 10 pF - 1 µF V good Good V good High quality, often used in filters and the like where accuracy is needed.
Polycarbonate 100 pF - 20 µF V good V good Good Used in many high tolerance and hash environmental conditions. Supply now restricted.
Polypropylene 100pF - 50 µF V good Good V good High performance and low dielectric absorption.
Teflon 100 pF - 1 µF V good V v good V v good High performance - lowest dielectric absorption.
Glass 10 pF - 1000 pF Good Good V good Excellent for very harsh environments while offering good stability. Very expensive.
Porcelain 100 pF - 0.1 µF Good Good Good Good long term stability
Vacuum and air 1 pF - 10 000 pF       Often used as variable capacitors in transmitters as a result of their very high voltage capability.

jb Feature Film Capacitor

薄膜电容器(MKT,MKP,CL11,CL21,Interference Suppression Film Capacitor)具有很多优良的特性,是一种性能优秀的电容器, 它的主要等性如下:

无极性,绝缘阻抗很高,频率特性优异(频率响应宽广),而且介质损失很小。基于以上的优点, 所以薄膜电容器(MKT,MKP,CL11,CL21,Interference Suppression Film Capacitor)被大量使用在模拟电路上。尤其是在信号交连的部份,必须使用频率特性良好,介质损失极低的电容器,方能确保信号在传送时,不致有太大的失真情形发生。

在所有的塑料薄膜电容(MKT,MKP,CL11,CL21,Interference Suppression Film Capacitor)当中,又以聚丙烯电容(MKP,Interference Suppression Film Capacitor)和聚苯乙烯电容(Polystyrene Capacitor)的特性
最为显著。通常的薄膜电容器(MKT,MKP,CL11,CL21,Interference Suppression Film Capacitor)其制法是将铝等金属箔当成电极和塑料薄膜重迭后卷绕在一起制成。但是薄膜电容器(MKT,MKP,CL11,CL21,Interference Suppression Film Capacitor)又有一种制造法,叫做金属化薄膜(Metallized Film),其制法是在塑料薄膜(Plastic Film)上以真空蒸镀上一层很薄的金属以做为电极。

如此可以省去电极箔的厚度,缩小电容器单位容量的体积,所以薄膜电容器(MKT,MKP,CL11,CL21,Interference Suppression Film Capacitor)较容易做成小型,容量大的电容器.

jb Capacitors Company Definition

Capacitor is an electromechanical device capable of storing electrical energy (electrons). It differs from a battery, as a battery produces electrical energy as a by-product of chemical activity. A capacitor can function in a circuit like a battery. Or a resistor, or an inductor, for that matter. It can also absorb energy, turning some into heat.

A farad of capacitance is a lot of capacitance. In high voltage, we generally deal in microfarads (mfd.) or picofarads (pf) which are one millionth of a farad and one millionth of 1 millionth of a farad, respectively. Infrequently used, a nanofarad is one thousandth of a microfarad.
