Also referred to as a condenser, a capacitor is a passive electrical component widely used to store electricity as an electrical charge. 
There are many types of capacitors available on the market. You can find very small ones available as capacitor beads utilized in resonance circuits. 
Large power factor correction capacitors are also available from very small to huge capacitors and everything in between, you would find a wide range of capacitors. However, they all serve one function and that is to store electrical charge.
 
The simplest type of capacitor available consists of 2 parallel conductive plates. These plates are separated via dielectric, an insulating material. 
This insulating layer interrupts the flow of DC current via the capacitor. Instead of DC current, a voltage across the plates is present in the form of an electrical charge.
Conductive plates are available in various shapes such as circular, cylindrical and rectangular. The insulating layer is either in the form of waxed paper, Air, Plastic or even in certain type of liquid gel. 
 
Electrical charge can be of two types namely positive and negative. Positive charge is present in the form of protons and negative charge in the form of electrons. The positive charge collects on a plate as soon as a voltage is placed across a capacitor. This is followed by a corresponding negative charge accumulation on the other plate. For each particle of positive charge a mining at one plate, a charge from similar will depart from- ve plate. The plates charge neutral. This is a potential different obtained from charge existing between two plates. The amount of charge that was deposited on the plates and the amount of capacitance the capacitor posses.
Capacitance is defined as the electrical property of a capacitor. It is the measure of the ability of capacitors for storing an electrical charge on two plates. In case, a voltage of (V) volts is connected across 2 plates capacitors, a positive electrical charge (2) will be present on one plate in coulombs and a negative charge on the other.This indicates that the capacitor will possess a capacitance valve equivalent to the amount of charge divided by voltage running across. This will proved the capacitance equation of (C=QV).

A good capacitor will have high dielectric resistance as well as zero plate resistance. This results in the charge flowing across the plates remaining constant for an indefinite period of time as soon as the source voltage was removed.

To read a potentiometer, you need a multimeter. Put in on the proper ohmmeter setting, which should be higher than that of the resistance rating of the potentiometer as noted on the package or the device. If you don't know the resistance rating, use the lowest setting of the multimeter and increase it until you get a reading.

When reading the potentiometer, one multimeter lead must always be on the wiper or middle part, and the other one can be on either of the remaining terminals. For example, place one multimeter lead on the wiper, and the other on the left terminal of the potentiometer. If you place one lead on the left terminal and the other on the right, you will read the entire value of the pot, and the resistance will not vary when you turn the knob.

Note that Inexpensive ones may approximate only fifty percent of their rated value when they are measured.

We can offer all kinds of trimming potentiometers accept very small quantity with very competetive price, the delivery time is 2 weeks around. With our good support, our sales is keep increasing each month.Any questions ,please contact us at once.

Trimming Potentiometers come in different types.
Rotary and trimming potentiometers are wire wound, and are single or multi-turn, depending on the number of times the knob may be turned. The resistance is lowered or increased by turning the knob clock or counterclockwise, where the knob direction is dependent on the end that is used with the wiper.Faders or sliders as they are also known, have a rectangular shape, and the wiper moves back and forth in a linear fashion.
 
Potentiometers work by having a resistive element inside. Both end terminals are attached to it, and do not move. The wiper travels along the strip when the knob is turned. The closer the wiper is to the end terminal it is wired in conjunction with, the less the resistance, because the path of the current will be shorter. The further away it moves from the terminal, the greater the resistance will be.

The symbol for a potentiometer is the same one as a resistor, save for an arrow in the middle. In a circuit where they are used strictly as variable resistors or rheostats, only two terminals are wired to the other components. All three terminals are wired separately when they function as voltage dividers. Light dimmers in houses and volume controls on electronics are two common applications. Others include switches and position sensors.
 
Suntan Trimming Potentiometers selling keep increasing
Suntan can offer all kinds of Trimming Potentiometers, as below:TSR-3006 - Rectangular Trimming Potentiometers TSR-3323 - 7 Terminal Square Trimming Potentiometers TSR-3296 - 5 Terminal Square Trimming Potentiometers TSR-3362 - 9 Terminal Square Trimming Potentiometers TSR-3386 - 8 Terminal Square Trimming Potentiometers.
 

Suntan Trimming  potentiometer is an electrical component with a variable resistance.

In electrical engineering parlance, the term "potentiometer" is used in either one of two ways. It may refer to an instrument that measures an unknown emf or voltage by comparing it to a standard emf. In this capacity, it is functioning as a null instrument; it permits precision measurement by adjusting a value of a circuit element until a meter reads zero. Alternatively, "potentiometer" may refer to an electronic component that is used to vary resistance in a circuit.

A potentiometer is also referred to as a variable resistor or pot. They have three terminals, where the one in the middle is known as the wiper, and the other two are known as ends. The wiper is a movable contact where resistance is measured with respect to it and either one of the end terminals.

They are useful for circuits where the resistance needs to be dynamically changed to control the current. They are also popular as voltage dividers .

Suntan is a Hong Kong based manufacturer of Trimming Potentiometers of different types. Including SMD Trimming Potentiometers, Rectangular Trimming Potentiometers, Wirewould Trimming Potentiomers, Phenolic Trimming Potentiometers . Please refer to below product image  of Trimming Potentiometers.

Suntan Silver mica (SM) capacitors are high precision, stability and reliability capacitors. They are available in small values, and are mostly used at high frequencies.

Generally known as silver mica capacitors, these rendered clamped mica capacitors obsolete. Instead of being clamped with foils these are assembled from sheets of mica coated on both sides with deposited metal. The assembly is dipped in epoxy. The advantages are:

1.greater stability, since there are no capacitive airgaps that can change dimension

2.airtight enclosure removes the risk of oxidation or corrosion of plates or connections

3.greater capacitance per volume, since

4.there are no airgaps between plates and mica,

5.the conducting surfaces can be thinner.

6.no clamping mechanism is needed

Suntan is a manufacturer of Mica Capacitors. Please refer to below product image of Mica Capacitors.For more details,please feel free to contact us.

Suntan aluminum Electrolytic capacitors store charge in a chemical paste called an electrolyte. They have large capacitance values, and are inexpensive and durable. Electronic designers typically use electrolytic capacitors to remove electrical noise from circuits. Since these capacitors are polarized, you must pay attention to the positive and negative leads or risk an explosion. When you use electrolytic aluminum capacitor, note that it has its capacitance and voltage values clearly printed on the body of the part. 

Electrolytic capacitors have capacitance ratings in the range of 10 to 200,000 microfarads. The voltage rating is the maximum voltage to which the capacitor should be subject. Maximum voltages for electrolytic generally range from 20 to 600 volts.

Suntan manufacture a wide range 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.
