Detailed explanation of the application of various components in EMC

Starting from this section, we will focus on analyzing the applications of various components in EMC, typically including inductors, capacitors, magnetic beads, resistors, and magnetic rings. The first is the capacitor. 1. In EMC design, the characteristics of the aforementioned components are related to an important factor, such as frequency. Talking about capacitors, inductors, and magnetic beads without discussing frequency is meaningless. Capacitance can be understood as the series connection of parasitic inductance and capacitance. When the frequency exceeds the resonant frequency, the capacitive reactance is smaller than the inductive reactance, and the circuit gradually exhibits inductance characteristics. The resonant frequency can be calculated using the following formula. f =1/（2π√C […]
