Capacitor
SMD capacitors are used in vast quantities within
the manufacture of all forms of electronic equipment. After SMD resistors they
are the most widely used type of component. There are many different types of
SMD capacitor ranging from ceramic types, through
tantalum varieties to electrolytic and more.
The working and functionality are as similar to the
conventional type of capacitor. Storing and destroying process of a capacitor
are same for all type of capacitor.
Ø This type of
capacitor which is commonly used in small space circuit like the cell phone, uses
the Tantalum type of capacitor,
Ø Tantalum capacitors are used in
smaller electronic devices including portable telephones, pagers, personal
computers, and automotive electronics.
Ø It also offer
smaller size and lower leakage than standard.
There are two types of Capacitors used in Mobile Phones
Circuits,
Ø The Polarized and Non-Polarized Capacitors.
The Polarized
Capacitor
Tantalum Capacitors which is polarized, and may be used in DC circuits.
Typical values range from 0.1uF to 470uF.
Standard Tantalum values change in multiples of 10, 22, 33,
and 47. Normal Temperature Coefficient [TC] for Tantalum Capacitors is +5%.
Polarized capacitors are typically used in large voltage situations, such as DC line filtering to reduce noise related to uneven voltage levels after rectification from an AC source. Mainly measured in microfarads. Polarity is critical to these devices. They are marked with the voltage rating (usually double the circuit voltage used) as well as the farad marking.

Non-Polarized Capacitor
Non-polarized are similar to polarized except the plates are similar metal.

Non-polarized caps are typically used in low
voltage situations, both AC and DC. Polarity is not critical. Measured in pico
