jb Capacitors in Series with Mains & in Parallel

For capacitors in parallel

Capacitors in a parallel configuration each have the same applied voltage. Their capacitances add up. Charge is apportioned among them by size. Using the schematic diagram to visualize parallel plates, it is apparent that each capacitor contributes to the total surface area.

Several capacitors in parallel.

For capacitors in series

Connected in series, the schematic diagram reveals that the separation distance, not the plate area, adds up. The capacitors each store instantaneous charge build-up equal to that of every other capacitor in the series. The total voltage difference from end to end is apportioned to each capacitor according to the inverse of its capacitance.

Several capacitors in series.

The entire series acts as a capacitorsmaller than any of its components.

Capacitors are combined in series to achieve a higher working voltage, for example for smoothing a high voltage power supply. The voltage ratings, which are based on plate separation, add up. In such an application, several series connections may in turn be connected in parallel, forming a matrix. The goal is to maximize the energy storage utility of each capacitor without overloading it.

jb E3 & E6 Series Values

1.)Capacitors Breakdown voltage

Main article: Breakdown voltage

The breakdown voltage of the dielectric limits the power density of capacitors. For a particular dielectric, the breakdown voltage is proportional to the thickness of the dielectric.

If a manufacturer makes a new capacitor with the same dielectric as some old capacitor, but with half the thickness of the dielectric, the new capacitor has half the breakdown voltage of the old capacitor.

Because the plates are closer together, the manufacturer can put twice the parallel-plate area inside the new capacitor and still fit it in the same volume (capacitor size) as the old capacitor. Since the capacitance of a parallel-plate capacitor is given by: 

this new capacitor has 4 times the capacitance as the old capacitor.

Since the energy stored in a capacitor is given by: 

This new capacitor has the same maximum energy density as the old capacitor.

The energy density depends only on the dielectric. Making a few thick layers of dielectric (which can support a high voltage, but results in a low capacitance), or making many very thin layers of dielectric (which results in a low breakdown voltage, but a higher capacitance) has no effect on the energy density.

2.) Standard values

Before 1960 electronic components values were not standardised. The more common, but not the only, values for capacitors were 1.0, 1.5, 2.0, 3.0, 5.0, 6.0, and 8.0 as base numbers multiplied by some negative or positive power of ten. Values of 0.001 µF and above were stated in microfarads (µF, or often mF); lower values were stated in micro-microfarads (µµF, now called picofarads, pF).

In the late 1960s a standardized set of geometrically increasing preferred values was introduced. According to the number of values per decade, these were called the E3, E6, E12, etc. series

In many applications capacitors need not be specified to tight tolerance (they often need only to exceed a certain value); this is particularly true for electrolytic capacitors, which are often used for filtering and bypassing. Consequently capacitors, particularly electrolytics, often have a tolerance range of ±20% and need to be available only within E6 (or E3) series values.

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.
