A capacitor constructed by stacking, or forming into a roll, alternate layers of foil and a dielectric which consists of a plastic, such as polystyrene or Mylar, either alone or as a laminate with paper.Plastic film capacitors help suppress interference and simultaneously decouple semiconductors or are used as DC link capacitors.

Suntan have 4 types of Axial Film Capacitors, they are differ with different material and different body style.

Suntan have Metallized Polyester Film Capacitor with Cycloidal & Oval body style and Metallized Polypropylene Film Capacitor with Cycloidal & Oval body style also.

The temperature can up to 105'C at most.

They are mainly used in different instruments, DC & AC circuit of the household equipment and the fractional frequency circuit of acoustics system.

The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having highly perfect basal cleavage. All are monoclinic with a tendency towards pseudo-hexagonal crystals and are similar in chemical composition. The highly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.

The word "mica" is thought to be derived from the Latin word micare, meaning "to glitter", in reference to the brilliant appearance of this mineral (especially when in small scales).

Based on Mica’s characteristic and other function .Suntan is supplying Silver mica capacitors which are high precision high stability high reliability capacitors. They are available in small values, and are mostly used at high frequencies.

Suntan The Capacitance of Aluminum Electrolytic Capacitors

July 22, 2011 Views
Comments 0

The capacitance value of any capacitor is a measure of the amount of electric charge stored per unit of potential difference between the plates. The basic unit of capacitance is a farad; however, this unit has been too large for general use until the invention of the double-layer capacitor, so microfarad (μF, or less correctly uF), nanofarad (nF) and picofarad (pF) are more commonly used.

The capacitance of aluminum electrolytic capacitors tends to change over time, and they usually have a tolerance range of 20%. Some have asymmetric tolerances, typically −20% but with much larger positive tolerance as many circuits merely require a capacitance to be not less than a given value.Tantalum electrolytics can be produced to tighter tolerances and are more stable.

Suntan is a Hong Kong based manufacturer of Aluminum Electrolytic Capacitors, Including Snap-in type Electrolytic Capacitor, Screw type and LUG type Aluminum Electrolytic Capacitor, Axial & Radial Electrolytic Capacitor and SMD Aluminum Electrolytic Capacitor etc.

Capacitors may retain a charge long after power is removed from a circuit; this charge can cause dangerous or even potentially fatal shocks or damage connected equipment. Service procedures for electronic devices usually include instructions to discharge large or high-voltage capacitors. Capacitors may also have built-in discharge resistors to dissipate stored energy to a safe level within a few seconds after power is removed.

Our Suntan has produce a Safety Standard Recognized Capacitor ,It’s specifications is descriped its function detailedly as follows.

Suntan High-Frequency of Ceramic capacitors

July 18, 2011 Views
Comments 0

Ceramic capacitors are suitable for moderately high-frequency work (into the high hundreds of megahertz range, or, with great care, into the low gigahertz range), as modern ceramic caps are fairly non-inductive compared to the other major classes of capacitors (film and electrolytic). Capacitor technologies with higher self-resonant frequencies tend to be expensive and esoteric (typically, mica or glass capacitors).

Suntan For Mica Capacitor and Mica

July 15, 2011 Views

Mica capacitors are high precision high stability high reliability capacitors. They are available in small values, and are mostly used at high frequencies.

Mica has a high dielectric strength and excellent chemical stability, making it a favoured material for manufacturing capacitors for radio frequency applications. It has also been used as an insulator in high voltage electrical equipment, and between the bars of commutators in direct current motors and generators. Mica is used because it can be split into very thin slices, and this keeps its thermal resistance low while retaining sufficient dielectric strength to prevent current from flowing across it at moderate voltages. The insulation is usually necessary when the heat sink is earthed (grounded) while the electronic component's metal surfaces will be connected to a power supply or signal line. If they were in direct contact this could form a short circuit. Heat sink insulation can also be necessary to prevent the heat sink from acting like an antenna if the component is connected to a rapidly varying signal.

Suntan Varistor

July 13, 2011 Views
Comments 0

A varistor is an electronic component with a "diode-like" nonlinear current–voltage characteristic. The name is a portmanteau of variable resistor. Varistors are often used to protect circuits against excessive transient voltages by incorporating them into the circuit in such a way that, when triggered, they will shunt the current created by the high voltage away from the sensitive components. A varistor is also known as Voltage Dependent Resistor or VDR. A varistor’s function is to conduct significantly increased current when voltage is excessive.

Our Suntan is engaged dipped varistor .if our Varstor will meet your requirements , I hope you can visit our website for the detailed information. Varistor are very popular all over the world, so we are. Believe us ,you won't be disappointed!

Suntan Technology Company Limited
----All Kinds of Capacitors

The tantalum capacitor is a highly reliable type of solid capacitor or electrolytic capacitor. Surface mount tantalum capacitors are increasingly being used in circuit designs because of their volumetric efficiency, basic reliability and process compatibility.

Tantalum capacitors are manufactured from a powder of relatively pure tantalum metal. The typical particle size is between 2 and 10 μm. Surface area is expressed in capacitance (C) in microfarads (µF) times voltage (V) in volts (V) per gram of powder (CV/g) Note the very great difference in particle size between the powders.

Our Suntan Technology Company has many types of tantalum capacitors ,such as Dipped Tantalum Capacitor-TS19,Please see the detailed information on our for your reference ,and welcome your enquiry about our all kinds of capacitors.
