Suntan Introduces Four Kinds of Plastic Film Capacitors

Posted May 10,2013 * Comments(0)

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.

Capacitor type Dielectric used Features/applications Disadvantages
PET film Capacitor Polyester film Smaller in size when compared to paper or polypropylene capacitors of comparable specifications. May use plates of foil, metalized film, or a combination. PET film capacitors have almost completely replaced paper capacitors for most DC electronic applications. Operating voltages up to 60,000VDC and operating temperatures up to 125°C. Low moisture absorption. Temperature stability is poorer than paper capacitors. Usable at low (AC power) frequencies, but inappropriate for RF applications due to excessive dielectric heating.
Kapton Capacitor Kapton polyimide film Similar to PET film, but significantly higher operating temperature (up to 250°C). Higher cost than PET. Temperature stability is poorer than paper capacitors. Usable at low (AC power) frequencies, but inappropriate for RF applications due to excessive dielectric heating.
Polystyrene Capacitor Polystyrene Excellent general purpose plastic film capacitor. Excellent stability, low moisture pick-up and a slightly negative temperature coefficient that can be used to match the positive temperature co-efficient of other components. Ideal for low power RF and precision analog applications Maximum operating temperature is limited to about +85°C. Comparatively bigger in size.
Polycarbonate Plastic Film Capacitor Polycarbonate Superior insulation resistance, dissipation factor, and dielectric absorption versus polystyrene capacitors. Moisture pick-up is less, with about +/- 80 ppm temperature co-efficient. Can use full operating voltage across entire temperature range (-55°C to 125°C) Maximum operating temperature limited to about 125°C.

Suntan Introduces Capacitor's Current , Voltage and Energy

---All Kinds of Capacitors

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 ic(t) is equal to the capacitance of the capacitor,
times the derivative of the momentary capacitor's voltage vc(t):

i_c(t)=C\frac{dv_c(t)}{dt}
 

Capacitor's voltage 

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

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

v_c(t)=v_c(0)+\frac{1}{C}\int_{0}^{t}i_c(\tau)d\tau
 

Energy of capacitor

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

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

EC = C × VC 2 / 2

 

Suntan Show the Schematic Diagram of Series Capacitor and Shunt Capacitor

Suntan Technology Company Limited
---All Kinds of Capacitors 

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 series

 

  

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

\frac{1}{C_{Total}}=\frac{1}{C_{1}}+\frac{1}{C_{2}}+\frac{1}{C_{3}}+...
 

Capacitors in parallel

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

CTotal = C1+C2+C3+...

Suntan Provides Some Common Capacitor Symbols for Customer Reference

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 symbol Capacitor
polarized capacitor symbol Polarized Capacitor Electrolytic capacitor
polarized capacitor symbol Polarized Capacitor Electrolytic capacitor
variable capacitor symbol Variable Capacitor Adjustable capacitance

Suntan Tell Our Customers What is Capacitors?

Since 1978, Suntan Technology Company Limited started in selling all kinds of capacitors from our headquarters in Hong Kong. Capacitors may not be strange to our custometrs, but how does it work? Presumably not many people know it, so here we will tell you.

Capacitor is an electronic component that stores electric charge. The capacitor is made of 2 close conductors (usually plates) that are separated by a dielectric material. The plates accumulate electric charge when connected to power source. One plate accumulates positive charge and the other plate accumulates negative charge. The capacitance is the amount of electric charge that is stored in the capacitor at voltage of 1 Volt. The capacitance is measured in units of Farad (F). The capacitor disconnects current in direct current (DC) circuits and short circuit in alternating current (AC) circuits.
