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.

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。

Arcotronics Kemet, Epcos,Pilkor, EVOX RIFA, Panasonic lead time is very very long, one customer told me this morning Arcotronics Kemet R46 X2 need 371days, that is 53 weeks, over 1 year....

But JB X2 lead time is only 5-7 weeks, for common value like 0.1uF even can meet 4-5 weeks.

Jb Capacitors produce MKT, MKP, X2 film capacitors and electrolytic capacitors. We have cross for above mentioned brands, we produce and sell under jb capacitors brand.

Currently for X2, below is most popular items we sell, widely used for Power supply, lighting products, and power meters, how about you ?

X2--0.022uF 275VAC P:15mm
X2--0.1uF 275VAC P:10mm
X2--0.1uF 275VAC P:15mm
X2--0.33uF 275VAC P:15mm

jb Capacitors Company Definition

0 comments 2010-7-2 11:24:6 views

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.
