1. 电阻(电路板元件)

我们在大多数PCB项目中经常使用电阻，我们大多数人都熟悉它们的功能;电阻器是电路板上最常用的元件之一，它们非常受欢迎，而且相当容易使用。因此，电阻器有助于以热的形式消散电能。电阻器有几种类型，分类方法也不同，制作电阻器所用的材料也往往不同，因为我们针对不同的目的使用不同的材料。

电阻的另一种不同方式是导线引出的方式，在这方面，最常见的类型是轴向电阻。电子发烧友、初学者和业余爱好者通常喜欢使用轴向电阻，因为它们很容易集成到任何电路中。每个电阻器周围都有环，这些环是一个颜色代码，表示特定电阻器的电阻值，这些环还告诉我们电阻器的可能公差。

2. 电容器(电路板组件)

在电阻器之后，电容大概是电路板上最常见的元件了，电容也是PCB爱好者的首选。然而，我们使用的电容器比电阻少。电容器的基本功能是在其中储存电荷，电容器由两个金属板组成，两个金属板之间有一个电介质，两个金属板存储相反的电荷，电介质有助于将它们分开。这样，电流就开始流过电路。

电容器的分类方法多种多样。然而，我们主要根据介质材料对电容器进行分类。这是因为电介质材料负责赋予电容器关键特性;介质材料越致密，电容器能在其极板上储存的电荷就越多;这就是为什么我们倾向于使用高质量的材料来制造电容器，以获得更高的电容…一个典型的电容器有两根金属板伸出来…我们用这些线将电容器集成到电路中。

3. 电感器(电路板元件)

电感是电路板无源线性元件的三个成员之一，另外两个是电容和电阻器，电感也主要用来在其中储存能量，但它们是通过产生磁场来储存能量，而电容是通过利用静电获得能量来储存能量。有许多类型的电感器，其中一些非常简单，而另一些则非常复杂。然而，金属线圈是你会遇到的最常见和容易理解的电感器。线圈可能产生的磁场取决于线圈的匝数，因此匝数越大，电感越大。

我们经常看到电感器缠绕在一些磁芯上，这些磁芯有不同的形状和大小，其主要目的是在电流通过导体时增强磁场，使磁芯允许我们完全过滤。阻断特定信号。这对我们来说非常有用，因为我们可以在许多应用中使用它，包括减少对通信设备的干扰和延长电池寿命。

4. 电位器(电路板元件)

电位器基本上是简单电阻器的高级形式。但是，电位器的电阻值可以根据需要改变。电位器有很多种类型，但最常见的是线性和旋转型，您可以通过拖动线性滑块来改变线性电位器的电阻。在旋转电位器上，你可以转动旋钮来改变电阻。当滑块在半圆形基础阻力上移动时，阻力会发生变化。

我们经常在日常应用中使用旋转电位器，最常见的应用之一是在音乐播放器和类似音频设备的圆形音量控制器中使用它们，它们通过控制传递到放大器的电流量来工作。在设计复杂的设备时，需要通过微调来改变其性能。

1. Resistance (components of the circuit board)

We use resistors regularly in most PCB projects, and most of us are familiar with their functions; Resistors are one of the most commonly used components on a circuit board, they are very popular and fairly easy to use. The flow of electricity… Thus, resistors help dissipate electrical energy in the form of heat. There are several types of resistors, the classification methods are also different, and the materials used for making resistors are often different, because we use different materials for different purposes.

Another different way of resistors is the way the wire is led out, and in this regard, the most common type is the axial resistor. Electronics enthusiasts, beginners, and hobbyists often like to use axial resistors because they are easy to integrate into any circuit. Each resistor has rings around it, these rings are a color code indicating the resistance value of that particular resistor, and these rings also tell us about the possible tolerances of the resistor.

2. Capacitors (components of the circuit board)

After resistors, capacitors are probably the most common component on a circuit board, and capacitors are also the first choice for PCB enthusiasts. However, we use fewer capacitors than resistors. The basic function of a capacitor is to store charge in it, a capacitor consists of two metal plates with a dielectric between the two metal plates, the two plates store opposite charges, and the dielectric helps to separate them. In this way, current begins to flow through the circuit.

Capacitors are classified in a variety of ways. However, we mainly classify capacitors according to their dielectric material. This is because the dielectric material is responsible for giving the capacitor key characteristics; The denser the dielectric material, the more charge the capacitor can store on its plate; This is why we tend to use high-quality materials to make capacitors in order to obtain higher capacitance… A typical capacitor has two wires sticking out of a metal plate… We use these lines to integrate the capacitor into the circuit.

3. Inductors (circuit board components)

Inductors are one of three members of the passive linear component of the circuit board, the other two are capacitors and resistors, inductors are also mainly used to store energy in them, but they store energy by generating magnetic fields, while capacitors are used to store energy by using static electricity to obtain energy. There are many types of inductors out there, some of which are very simple while others are very complex. However, metal coils are the most common and easily understood inductors you will encounter. The magnetic field that the coil may produce depends on the number of turns of the coil, so the greater the number of turns, the greater the inductance.

We often see inductors wrapped around some magnetic core, which has different shapes and sizes, the main purpose of which is to enhance the magnetic field as the current passes through the conductor, so that the magnetic core allows us to filter completely. Block specific signals. This is very useful for us because we can use it for many applications, including reducing interference to communication devices and extending battery life.

4. Potentiometer (circuit board components)

Potentiometers are basically advanced forms of simple resistors. Simple resistance with fixed resistance value… However, the resistance value of the potentiometer can be changed as needed. There are many types of potentiometers, but the most common are the linear and rotary types, and you can change the resistance of the linear potentiometer by dragging the linear slider. On a rotary potentiometer, you can turn the knob to change the resistance. The resistance changes as the slider moves over the semi-circular base resistance.

We often use rotary potentiometers in everyday applications, and one of the most common applications is to use them in circular volume controllers in music players and similar audio devices, where they work by controlling the amount of electrical flow passed to the amplifier. Potentiometers When designing complex equipment, its performance needs to be changed by fine tuning.
