2. The difference between inductance, bead and 0 ohm resistorInductance: inductor is a energy storage element, many for the Power filter circuit, LC oscillation circuit, low frequency filter circuit, etc., its application frequency is rarely more than 50MHz. For inductance, the inductance value is proportional to the frequency. XL = 2ΠFL to illustrate, wherein the XL is inductance, the unit is Ω, for example an ideal 10mH inductor, at 10KHz, inductanc

1 : no function is provided in the circuit. It is only for convenience of debugging or Compatibility Design on the PCB. 2 : Jumper can be used. If a line is not used, do not paste the resistor directly (without affecting the appearance) 3 : when the matching circuit parameters are uncertain, use 0 ohm instead. during actual debugging, determine the parameters, then, it is replaced by a component of a specific value. 4. when you want to test the

In the Excel European symbol how to play, I believe for a lot of skilled with Excel friends, is very simple, but for some beginners, is a rookie, it is a little hazy feeling, after all, just contact with the things have not been used. But, it doesn't matter today I will help beginners to solve this problem, help beginners quickly understand Excel, in Excel How to quickly enter the ohm symbol. This method is many, wait for the author one by one: The e

impedance of the noise signal on the signal reflux path. In addition, we often use a digital-analog hybrid circuit below 10 MHz instead of separating digits from analog ones with 0-euro resistance, instead, we choose to apply 0 euro resistance or iron magnet to the power source ground, because at this time, only the power supply can be regarded as "clean ", both the analog and digital locations are noisy. The following figure shows a total of five locations, namely, signal, analog, digital, pow

, which is often seen in the ordinary board, in order to allow automatic Mounter and automatic plug-in machine to work properly, with 0 resistors instead of cross-line.The effect of the 0 ohm resistor is as follows:1, in the circuit does not have any function, just on the PCB for debugging convenience or compatible design and other reasons.2, can do jumper, if a segment of the line is not used, directly subsidize the resistor can (not affect the appea

series of inductance and resistance. It is an energy storage component and is often used in a medium and low frequency filter circuit that does not exceed 50 MHz. The main parameters of Inductance are DC resistance (DCR, defined as the DC resistance of components without AC signal), rated current and low Q value. When used as a filter, the Wide Bandwidth feature is desired, so the high Q feature of the inductor is not required. The low DC resistance (DCR) can ensure the minimum voltage drop. 0

There must be a process of my mother before entering the human fa-local stage. The human body is the body of the day after tomorrow formed by the refined blood of the parents. The human body obtains the genetic information from the parents who are born with the innate truth and inherit the recessive physiological tissue structure of the parents, after the birth of her mother in October, she came to the world. Breastfeeding completes the process There must be a process of my mother before enterin

"MBA China Network " in the management, there are always some effective laws and secrets worthy of us to continue to explore. Here are a few simple but easy-to-ignore rules of management that may help you understand the business.The law of Rotten applesIn any organization, there are a few hard-to-manage characters, like rotten apples in an apple case, and if you don't deal with it, it will quickly infect and rot the other apples in the fruit box. The

"The natural graphs commonly found in the Real-world have, highly skewed Power-law degree distributios ..." is the beginning of the paper, it says. The solution is probably, and then the investigation was known. Power-law degree Distributios is originally a description of the distribution of nodes in the network map, Chinese can be called "Power law degree distri

The basic economic law of Socialism is the law of economic benefitOver the years, there are many different viewpoints about the basic economic law of socialism, but I think it is basically a dispute about how to explain and understand the argument of the Soviet Socialist economic problem. This year, the third issue of the "Economic Research" published the Wang Ju

To understand the performance of a system, we usually refer to some metric values (metric). We will discuss how to calculate these metric values. Little Law (queuing theory: liter law) and Utilization Law are common rules of Performance Engineering (part of system engineering). They are both mathematical theories and can be used as the theoretical basis of perfor

Dear daughter-in-law! On the eve of your upcoming new family with my son, I hope we can exchange some ideas on relevant issues for the sake of family stability and unity in the next few years. I. Economic problems: the so-called economic foundation determines the upper-layer architecture. Let's talk about this issue first. 1. My son graduated from a prestigious school. Now, even if I change my job, I don't have to worry about the economy. He has an an

Crocodile rule (Alligator Principle)One of the technical rules of economic trading, also known as the "crocodile effect", is that if a crocodile bites your foot, if you try to break out of your foot with your hand, the crocodile will bite your feet and hands at the same time, and the more you struggle, the more you will be bitten. Natural weakness of human nature, will affect our operation, a big loss, enough to lose 99 of the previous profit, so strict adherence to the

Network War law: Recently, the New York Times reported that the United States may use nuclear weapons to counter the destructive cyber attacks of hostile countries. In November 2017, a video entitled "Slaughterbots" was widely spread on social media and alleged that "artificial intelligence (AI) the controlled drone fleet can launch precise attacks against thousands of u

classes are consistent and legal. Although programmers make reasonable assumptions about the base class, the method they write will still lead to model design failure. 10. solutions cannot be viewed in isolation. They must be viewed based on the reasonable assumptions made by the design user. 11. A square in a mathematical sense may be a quadrilateral, but a square object is not a rectangle object, because the behavior of a square object is inconsistent with that of a rectangle object! 12. I
