2. Working principle of chip fixed resistors
The working principle of chip fixed resistors is based on Ohm's law, that is, the relationship between voltage (V), current (I) and resistance (R) is V=I×R. This resistor is a two-terminal passive component used to implement resistance like a circuit element. The current flowing through the resistor is proportional to the voltage across the resistor. Therefore, this relationship can be simply expressed using Ohm's law. For example, if a 100-ohm resistor is connected across a potential difference of 10 volts, a current of 0.1 amperes flows through the resistor.
Chip fixed resistors, commonly known as chip resistors, are one type of metal glass uranium resistors. It is a resistor made by mixing metal powder and glass uranium powder and printing it on a substrate using screen printing. This resistor is resistant to moisture and high temperature and has a small temperature coefficient. Its manufacturing process includes mixing metal powder and glass uranium powder, and then printing these mixtures on a substrate by screen printing to form the desired resistance value. This design enables chip fixed resistors to work stably in various environments, including humid and high temperature conditions, while maintaining a small temperature coefficient to ensure the stability of the resistance value. -
3. Resistor tolerance accuracy representation method
The tolerance accuracy of chip resistors refers to the allowable deviation range between the actual value of the resistor and the nominal value. In the digital identification, the tolerance accuracy is usually indicated by the last one or two digits. These numbers correspond to different accuracy levels, for example, 1% accuracy is usually indicated by the number "1", while 0.1% accuracy is indicated by the number "01".

4. 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%.
