How to look at the size of the chip capacitor? We can look at the model and specification of the chip capacitor, then what does the string of numbers in the model mean? I'm going to share it with you today.

There are two kinds of size representation of the chip capacitor, one is expressed in inches, and the other is expressed in millimeters. The series models of the chip capacitor are 0402, 0603, 0805, 1206, 1210, 1808, 1812, 2010, 2225, 2512, which is inch representation. 04 indicates that the length is 0.04 inches, 02 indicates that the width is 0.02 inches, and other similar model sizes (mm).
