2. What is the number of chip resistors?
Chip resistors are one of the commonly used components in electronic circuits, and their digital identification is an important basis for identifying resistance values and accuracy. The digital identification is usually printed on the surface of the resistor and consists of several digits. These digits not only indicate the specific resistance value of the resistor, but also imply the tolerance accuracy information of the resistor.

3. Resistor digital identification interpretation example
To better understand the interpretation method of chip resistor digital identification, let's look at an example. Assuming that the digital identification on a chip resistor is "1001", what is the resistance value of this resistor? What is the accuracy?
First, we interpret the first three digits "100", indicating that the resistance value is 100 ohms. Next, we look at the last digit "1", which indicates that the tolerance accuracy of the resistor is 1%. Therefore, the resistance of this chip resistor is 100 ohms and the tolerance accuracy is ±1%. -
