SMD Capacitor

The types of capacitor which is commonly used in small space circuit like the cellphone uses the Tantalum type of capacitor, 
Tantalum capacitors are used in smaller electronic devices including portable telephones, pagers, personal computers, and automotive electronics.
It also offer smaller size and lower leakage than standard. .
There are two types of Capacitors used in Mobile Phones Circuits,
The Polarized and Non-Polarized Capacitors.
This are the Capacitors may look like  that are being used in mobile phones circuit.

The Polarized Capacitor 
Tantalum Capacitors which is polarized, and may be used in DC circuits. Typical values range form 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. 

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

Decimal multiplier prefixes are in common use to simplify and shorten the notations of quantities such as component values.
Capacitance, for example, is measured in Farads, but the Farad is far too large a unit to be of practical use in most cases. For convenience, we use sub-multiples to save a lot of figures. For example, instead of writing 0.000000000001 Farads, we write 1pF (1 picofarad).
The more common prefixes and the relationships to one another are as follows.

Abbrev.	Prefix	Multiply by	or
p	pico	0.000000000001	10-12
n	nano	0.000000001	10-9
µ	micro	0.000001	10-6
m	milli	0.001	10-3
-	UNIT	1	100
k	kilo	1000	103
M	mega	1000000	106

Units
1000 pico units	=	1 nano unit
1000 nano units	=	1 micro unit
1000 micro units	=	1 milli unit
1000 milli units	=	1 unit
1000 units	=	1 kilo unit
1000 kilo units	=	1 mega unit
Tolerance All components differ from their marked value by some amount. Tolerance specifies the maximum allowed deviation from the specified value. Tolerances are normally expressed as a percentage of the nominal value. For example, a component with a marked value of 100 and a tolerance of 5% could actually be any value between 5% below the marked value (95) and 5% above the marked value (105).

How to Identify Capacitors Symbols and Layout

There are two types of capacitors, the Polarized and the Non-polarized. The Polarized is indicated with  ''+'' positive and ''-'' negative, meaning this cannot be change into its mounting position from a certain connection of a circuit polarity, The ''+'' positive is for the voltage supply line B+ only and the '' - '' negative is for the grounding lines. The capacitor will blown up if putting it into a non desired polarity position.
Non-polarized capacitor is a non-polar or without polarity meaning its position can be change without damaging it.
In Schematic Diagram it is stated as letter ''C'' stands for Capacitance then a mounting code and Capacitance value.

The Polarized indicated with desired maximum voltage value. like for example
C7597 1000mF_14V ,
the ''14V'' is the desired maximum voltage for that said capacitor.
While the Non-polarized labeled without desired voltage.
example: C2567 22pF

LG KP500 IMEI Change Without Any Box

1st if you want unlock:
step by step to unlock KP500

1- instal lg drivers, i think that this one is enough:

http://rapidshare.com

then connect mob with usb cable without battery,sim or any memory(mmc) it will find new hardware, let it install drivers auto

after install drivers remove phone from usb port

2- donwload this:

http://rapidshare.com

extract and put the file "KP500.flb" in c:\

3- open the software KP500-Utils-EN.exe

Press O ( Backup STATIC_EEP...)

then ENTER

then write: \\.\USB1 and press ENTER

then write: C:\KP500.flb and press ENTER

then write static_eep and press ENTER

then connect phone to usb and wait, it should create 2 files in Lg-utils folder, one with name STATIC_EEP with 80kb and other STATIC_EEP.big

delete the STATIC_EEP.big file

and copy STATIC_EEP file to c:\

4- then open again KP500-Utils-EN.exe software if you close it

write P (Unlock) then ENTER

then write c:\STATIC_EEP and ENTER

unlock code will appear

now turn on the phone, type 2945#*71001#

enter in UNLOCK SIM then NETWORK LOCK then it will ask you for code, type the code you got then phone unlocked


(to create KPXXX.flb files you should read this thread till step 3)
(after step 3 you dont need to read more, you have one or two .flb files then all you need to do is pick the bigger .flb file and copy to c:\ and

rename it to KPxxx.flb then unlock the same way as KP500 instructions
