Generally, the size of the patch components is very small. For example, for the 0201 patch, their length and width are less than 1 mm. For the length, it is only 0.6 mm and the width is only 0.3 mm. This is commonly used on mobile phone motherboards; In addition, a 0402 packaged SMD component is commonly used on computer motherboards, which is 1 mm long and 0.5 mm wide.

For the components in this package, from the color of the appearance, the black ones are chip resistors, and the beige ones are chip capacitors. The capacitance of this chip capacitor is very small, generally pF and nanofarads. (nF) level, such as chip capacitors marked with 103, its capacity is 10nF, 104 is 100nF, and so on.

So what is the role of chip resistors and chip capacitors in integrated circuit boards?

For the chip resistors and chip capacitors on these circuit boards, they actually play the same role in the circuit as the shaft-shaped resistors and column-shaped capacitors with pins. For example, chip resistors can also play the role of voltage divider, current limiter, and pull-up resistor and pull-down resistor in the circuit. This depends on the specific situation.

The same is true for SMD capacitors. Most of the "little points" of ordinary capacitors can be used. For example, they can be used for coupling, bypassing, filtering, etc. in the circuit.
