Suntan Ceramic Disc Capacitor - TS15

Posted May 15,2013 * 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, 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 Presents the Last Five Plastic Film Capacitors

Posted May 13,2013 * Comments(0)

Suntan Technology Company Limited
---All Kinds of Capacitors

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

Capacitor type

Dielectric used

Features/applications

Disadvantages

Polypropylene Plastic Film Capacitors

Polypropylene

Has become the most popular capacitor dielectric[citation needed]. Extremely low dissipation factor, higher dielectric strength than polycarbonate and polyester films, low moisture absorption, and high insulation resistance. May use plates of foil, metalized film, or a combination. Film is compatible with self-healing technology to improve reliability. Usable in high frequency applications due to very low dielectric losses. Larger value and higher voltage types from 1 to 100μF at up to 440V AC are used as run capacitors in some types of single phase electric motors.

More susceptible to damage from transient over-voltages or voltage reversals than oil-impregnated Kraft paper for pulsed power energy discharge applications.

Polysulphone Plastic Film Capacitors

Polysulfone

Similar to polycarbonate. Can withstand full voltage at comparatively higher temperatures. Moisture pick-up is typically 0.2%, limiting its stability.

Very limited availability and higher cost

PTFE Fluorocarbon (TEFLON) Film Capacitors

Polytetra- fluoroethylene

Lowest loss solid dielectric. Operating temperatures up to250°C, extremely high insulation resistance, and good stability. Used in stringent,

Large size (due to low dielectric constant), and higher cost than other film capacitors.

Polyamide Plastic Film Capacitors

Polyamide

Operating temperatures of up to 200°C. High insulation resistance, good stability and low dissipation factor.

Large size and high cost.

Metalized Plastic Film Capacitors

Polyester or Polycarbonate

Reliable and significantly smaller in size. Thin metalization can be used to advantage by making capacitors "self healing".

Thin plates limit maximum current carrying capability.

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

Posted May 8,2013 * Comments(0)

Suntan Technology Company Limited
---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 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,.. :
