电子元器件是指电子元件和电小型的机器、仪器的组成部分，其本身常由若干零件构成，可以在同类产品中通用,常见的电子元器件包括电阻、电容、二极管、 三极管、电感等器件。一般电路中， 常用的代号标识如下:

1.电阻电阻在电路中用"R”加数字表示，例如'R7' 就表示编号为7的电阻，电阻在电路中的主要作用为分流、限流、分压、偏置、滤波(与电容器组合使用)和阻抗匹配等。电阻的识别主要有 两种方法:数标法: 主要用于贴片等小体积的电路色标法:通常用于色环电阻器2.电容电容在电路中一般用“C"加数字表示，电容是由两片金属膜紧靠,中间用绝缘材料隔开而组成的元件。电容的特性主要是隔直流通交流。电容的是识别也是两种方法，即色标法和数标法。

Electronic components refer to the components of electronic components and small machines and instruments, which are often composed of several parts and can be used in similar products. Common electronic components include resistors, capacitors, diodes, transistors, inductors, and other devices. In general circuits, the commonly used code identification is as follows:

1. Resistance is represented by "R" and a number in a circuit, for example, "R7" represents a resistor numbered 7. The main functions of resistance in a circuit are shunt, current limiting, voltage sharing, bias, filtering (combined with capacitors), and impedance matching. There are two main methods for identifying resistance: number labeling method: mainly used for small volume circuits such as chips. Color labeling method: usually used for color ring resistors. 2. Capacitors and capacitors are generally used in circuits with "C" By adding numbers, a capacitor is a component composed of two metal films adjacent to each other, separated by insulating materials in the middle. The main characteristic of a capacitor is its direct current isolation. There are also two methods for identifying capacitors, namely color coding and number coding.
