Inductors and capacitors are common passive components in circuits. They play an important role in high-frequency circuits. Understanding their high-frequency characteristics is very important for designing and analyzing high-frequency circuits. This article will introduce the high-frequency characteristics of inductors and capacitors, including impedance Harmonious vibration. Inductor in high frequency circuit impedance It is mainly composed of its inductive reactance and resistance. Inductive reactance is that the inductor impedance , which is proportional to the frequency. The calculation formula of inductance is: Xl=2 π fL, where Xl is inductance, f is frequency, and L is inductance. The inductance of the inductor increases with the increase of frequency, which means that at high frequencies, the inductor has a stronger resistance to the current. This is because at high frequencies, the current

Resistance impedance And features impedance They are three concepts commonly used in circuits. They are used to describe the resistance of circuits to current and voltage, but they are different in specific applications and definitions. 1. Resistance: The resistance IRFP460APBF is a physical quantity that blocks the current flow in the circuit, expressed by the symbol R, and the unit is ohm (Ω). Resistance is an inherent property of conductor materials. Its resistance to current is mainly realized by the collision between electrons and atoms in the conductor. The size of the resistance depends on the length of the conductor, the cross-sectional area and the resistivity of the material. In the DC circuit, the role of resistance is to produce a voltage drop. According to Ohm's law, resistance and electricity

impedance Matching refers to the load required during energy transmission impedance Characteristics of the transmission line impedance Equally, the transmission at this time will not produce reflection, which indicates that all energy is absorbed by the load. Otherwise, there is energy loss in transmission. In high-speed PCB design, impedance The quality of the signal is related to whether it matches or not. When PCB wiring needs to be done impedance Match? It is not mainly about frequency, but the key is about the steepness of the edge of the signal, that is, the rise/fall time of the signal. It is generally believed that if the rise/fall time of the signal (calculated as 10%~90%) is less than 6 times the wire delay, it is a high-speed signal, which must be noted impedance Matching problem. The wire delay is generally 150ps

At present, there are many kinds of ESD protection devices on the market, but the most commonly used ones can be divided into three categories: polymer, varistor/suppressor and diode. The biggest difficulty in selecting the appropriate ESD protection device is how to determine which device can provide the maximum protection most easily. The system supplier generally compares the ESD protection device with the ESD rating (or nominal value) in the data manual. In fact, from these ratings, it can not be seen how strong the device protection system is. The key depends on other diode parameters. In addition to the ESD nominal value of the protection device, the voltage value (clamping voltage) and the current (residual current) at the ASIC terminal are also key factors
