Transistors and diodes: These components are often contained in a small plastic package. The connections are made via leads which emanate from the package and are bent so that they touch the board. Three leads are always used for these packages. In this way it is easy to identify which way round the device must go.

Passive SMDs:   There is quite a variety of different packages used for passive SMDs. However the majority of passive SMDs are either resistors or capacitors for which the package sizes are reasonably standardized. Other components including coils, crystals and others tend to have more individual requirements and hence their own packages.

Resistor and capacitor packages have a variety of packages. These have designations that include: 1812, 1206, 0805, 0603, 0402, and 0201. The figures refer to the dimensions in hundreds of an inch. In other words the 1206 measures 12 hundreds by 6 hundreds of an inch. The larger sizes such as 1812 and 1206 were some of the first that were used. They are not in widespread use now as much smaller components are generally required. However they may find use in applications where larger powers are needed or where other considerations require the larger size.

The connections to the printed circuit board are made through metallised areas at either end of the package.http://www.jbcapacitors.com/

SMDs, i.e. SMT components, by their nature are very different to the traditional leaded components. They can be split into a number of categories:

• Passive SMDs
• Transistors
• Integrated circuits

A capacitor is a passive electronic component that stores energy in the form of an electrostatic field.  In its simplest form, a capacitor consists of two conducting plates separated by an insulating material called the dielectric. Capacitance is directly proportional to the surface areas of the plates, and is inversely proportional to the plates' separation.

Capacitance also depends on the dielectric constant of the dielectric material separating the plates.

The standard units of Capacitance,

farad: F
microfarad: µF (1 µF = 10-6 F)
nanofarad: nF (1 nF = 10-9 F)
picofarad: pF (1 pF = 10-12 F)

For any good capacitors, welcome to find us.jb can help you in this regards.

Capacitors naturally wear out after extended periods of use. Most capacitors are designed to operate for several thousand hours. Here is the projected lifespan for a typical capacitor, rated for 4,000 hours of operation at an average core temperature of 167 degrees Fahrenheit (75℃).

Capacitors on a motherboard are used to absorb spikes in electrical current and to smooth the flow of power on the motherboard, protecting all of the computer’s components.
