I have got the ceramic capacitor in which it is printed as 330 AEC. Now I got confused whether it is a 330pf or 33pf. Can anyone help me in this.

Regards
Sanath

the last digit indicates the number of Zeros that have to be suffixed to the first two values

for eg: 330 -----> 3 3 ( zero indicates no 0's present) -----> 33pf
104 -----> 1 0 ( 4 zeros) ----> 1 0 0000 pf ---> 100nf --> 0.1uF
103 -----> 1 0 ( 3 zeros) -----> 1 0 000 pf ----> 10nf --> 0.01uF
474 -----> 4 7 ( 4 zeros) -----> 4 7 0000 pf ----> 470nf --> 0.47uF

further single letters will be also be printed to indicate tolerances :

like: J = +/- 5 %
K = +/- 10 %
G = +/- 20 %


hope this info cleared your doubts

the AEC is the company name - so don't get confused

First digit: first significant (I am calling it F)
Second digit: second significant (calling it S)
third digit: multiplier (calling it M)
fourth digit/letter: tolerance (calling it T)

As it is ceramic so capacitance will be in picoFarad
so your capacitance will become = F S x 10^M +/- T

if you have capacitor written 104 so capacitance is
1 0 x 10^4 +/- T(whatever letter mentioned) pF = 10x10000 pF = 100nF]]> contact@nospam.com (Ajay Bhargav) Tue, 06 May 2008 15:24:01 -0700 http://www.8051projects.net/forum-t9301.html http://www.8051projects.net/forum-t9301.html contact@nospam.com (Ajay Bhargav) Wed, 07 May 2008 00:40:20 -0700 http://www.8051projects.net/forum-t9301.html
