Hello forum
Are there any standards for size and color (of body) SMD capacitors?
If there are then where can i find documents about those?

For example i deassemble a capacitor with size about 4.6*2*1.7 (L*W*H) from a board but i can not find its package code.

 

SMD capacitors vary body and size depending on the type of capacitor. For example, see below some standards

 

Hello,

4.5 X 2 mm is an 4520 (metric code) or 1808 (inch code) :

A picture would help. The dimensions don't have units; I assume they're mm.

Small (e.g. 0603, 0805, ...) SMT ceramic caps don't have part numbers on them.
