Suntan Technology Company Limited
---All Kinds of Capacitors

Since 1978, Suntan Technology Company Limited started in selling all kinds of capacitors from our headquarters in Hong Kong, which of course include the ceramic disc capacitor. But what is ceramic disc capacitor? Many people don't really know, Suntan would like to introduce it now.  

A ceramic disc capacitor is a capacitor constructed with a ceramic disc as the dielectric. You'll recall that the basic definition of a capacitor is two conductors separated by an insulator (dielectric) of some kind. As a charge is driven onto one plate of a capacitor, the extra charge there builds up an electric field. Each charge arriving on one plate forces a charge off the other plate. Charge (and, therefore, voltage) builds. 

After reading the introduction of ceramic disc capacitor, in order to help clients enhance understanding, here take a Suntan products for example . This product is Suntan ceramic disc capacitor - TS15. Suntan ceramic chip capacitor is not only including TS15, of course, also including the TS16, TS17 ,etc.

Suntan Technology Company Limited
---All Kinds of Capacitors

In the last blog, we describesd four types of plastic film capacitaors of medium, application and disadvantage. Suntan presents the last five plastic film capacitors for our customers today.

Suntan Technology Company Limited
---All Kinds of Capacitors

Since 1978, Suntan Technology Company Limited started in selling all kinds of capacitors from our headquarters in Hong Kong. And the capacitor can be divided into nine types of PET film capacitor, Kapton Capacitor, Polystyrene Capacitor, Polycarbonate Plastic Film Capacitor. But very few people know their respective media, features and shortcoming. So Suntan introduces four kinds of different plastic film capacitor to our customers.

Dear customers, if you have been concerned about our blog, you will find that in the recent days, Suntan's blog described a series of  knowledge about capacitor. By doing this, not only in order to better serve our customers and to enhance custmoer understanding of capacitor, but also we are a company with decades of  producing capacitors, which have the ability and obligation to help our clients to know more about capacitor. Today, Suntan introduces the knowledge point about capacitor --- capacitor's current and voltage, as well as the energy of capacitor.

Capacitor's current

The capacitor's momentary current i_c(t) is equal to the capacitance of the capacitor,

times the derivative of the momentary capacitor's voltage v_c(t):

Capacitor's voltage

The capacitor's momentary voltage v_c(t) is equal to the initial voltage of the capacitor,

plus 1/C times the integral of the momentary capacitor's current i_c(t) over time t:

Energy of capacitor

The capacitor's stored energy E_C in joules (J) is equal to the capacitance C in farad (F)

times the square capacitor's voltage V_C in volts (V) divided by 2:

E_C = C × V_C ² / 2

As we all know, Suntan is a Hong Kong based manufacturer of Trimming Potentiometers, Capacitors, Varistors, the capacitor is its main product. The capacitor by category, can be divided into plastic film capacitors, aluminum capacitors, gold Capacitors, tantalum capacitors, etc. If according to the circuit diagram to points, can be divided into series capacitor and shunt capacitor. Therfore, Suntan shows these to our customers visa blow the schematic diagram.

Capacitors in parallel

The total capacitance of capacitors in parallel, C1,C2,C3,.. :

In our previous blog, Suntan tell our customers the working principle of capacitor. I believe you have a certain understanding after reading it. But when the manual comes with a number of capacitor symbols, you will feel these strange ,don't know what it means? Suntan lists some capacitor symbols visa blow table:

Capacitor Symbols
	Capacitor	Capacitor is used to store electric charge. It acts as short circuit with AC and open circuit with DC.
	Capacitor
	Polarized Capacitor	Electrolytic capacitor
	Polarized Capacitor	Electrolytic capacitor
	Variable Capacitor	Adjustable capacitance
