How to look at the size of the chip capacitor? Inch units and millimeter units
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).

Common resistor classification and derating usage rules
Resistance can be divided into three categories: fixed linear resistance, fixed nonlinear resistance, variable resistance, the reliability of the resistance mainly depends on the temperature of the resistance, and the temperature is the effect of the superposition of the ambient temperature and the heat generated by its own power loss.

Characteristics and uses of alloy resistance
Alloy resistance using alloy as the current medium resistance, alloy resistance is often called: metal alloy resistance, copper alloy resistance, sampling resistance, current detection resistance, low resistance value resistance, sensing resistance and so on.
