0402 chip capacitors are a type of small electronic components that are widely used in various electronic products, such as mobile phones, computers, televisions, etc., due to their small size.
This type of SMD capacitor not only has a compact appearance, but also has considerable withstand voltage, capable of withstanding voltages up to 50 volts, suitable for various applications.
The thickness of this capacitor is also very thin, usually around 0.2 millimeters, which can achieve high-density circuit design on PCB boards.
0402 chip capacitors can be used in various circuits, including DC circuits, AC circuits, and filters. In DC circuits, this type of capacitor can be used to distribute voltage and also achieve signal isolation and protection of the circuit.
In AC circuits, this type of capacitor can be used to achieve functions such as phase shift circuits and power factor correction circuits. In filters, this type of capacitor can be used to achieve functions such as low-pass filtering, high-pass filtering, and bandpass filtering.
