Surface Mount Capacitor
Surface mount capacitor are usually of brownish or yellowish colour, from the colour one can identify whether given component is capacitor to some extent.
But Most SM capacitors values are not identified in any way by visualising ,most of them think that they are identified according to there size but SIZE OF THE COMPONENTS DOES NOT INDICATE THE CAPACITANCE as each capacitor has a different number of layers according to there manufacturer.
The only way to "read" the value of these SM capacitor is via a capacitance meter.
But some of the SM capacitor has number on there surface as that of SM resistor (A three digit number or alphabets).
Similarly as SM resistor there values are indicated, i.e if the number is 107 then first two digit are the answer and the third digit is the number of zero's.
107 = 10 (two numbers) 0000000 (seven zero's)
These value of capacitor is given in pf, hence the value is 100000000pf = 100uf (100 microfarad).

Thank you for sharing this great tutorial on reading these capacitors!
ReplyDeletehey what it mean to have a 1A5 in a surface mount ceramic capacitor? 1A5 or IA5
ReplyDeleteNO PROPER WORD PLS READ CAREFULLY
Deletehahahhaaha
Deleteas per resister deatile as,
ReplyDelete01A=100ohms
01b=1kohms
01c=10kohms
to be continued
hi
ReplyDeleteI have a shorted SMD capacitor without code how can I find the code of the capacitor.
Pls help
You cannot find the code of capacitor, but if the capacitor is working you can measure the capacitance using capacitance meter.
DeleteOr else manufacturer can help you......
ok, assume the SMD capacitor is fualty and there is no hence on the board nor on the capacitor. like mobile phone circuit board. I couldnt even get the schematic.
ReplyDeletePlease my question how can I read the smd ceramic because they have deffarent color ie brown,gray and some light brown do they have code ?
ReplyDeleteI will appreciate your response.
